Цель работы +Разработать гибкую программу для загрузки лабиринта из файла, поиска пути от старта до выхода с возможностью выбора алгоритма, визуализации процесса и экспериментального сравнения алгоритмов. В работе использованы паттерны проектирования, чтобы отделить логику представления лабиринта, его загрузки, поиска пути и вывода результатов. + +## 2. Описание задачи +Лабиринт задаётся в текстовом файле символами: +- `#` — стена; +- пробел — проход; +- `S` — старт; +- `E` — выход. + +Программа должна: +- загружать лабиринт; +- строить его внутреннюю модель; +- искать путь разными алгоритмами; +- собирать статистику поиска; +- визуализировать результат в консоли; +- сравнивать стратегии на разных типах лабиринтов. + +## 3. Выбранные паттерны проектирования + +### 3.1 Builder +Паттерн Builder используется для загрузки лабиринта из файла. Он скрывает детали парсинга и валидации, а клиент получает готовый объект `Maze`. + +Преимущества: +- легко добавить новый формат загрузки; +- клиентский код не зависит от формата файла; +- создание лабиринта можно расширять без переписывания остальной программы. + +### 3.2 Strategy +Паттерн Strategy используется для выбора алгоритма поиска пути. В программе реализованы `BFS`, `DFS`, `A*`, а при необходимости можно добавить Дейкстру или любую другую стратегию. + +Преимущества: +- алгоритм можно менять во время выполнения; +- код оркестратора не зависит от конкретного метода поиска; +- новые алгоритмы добавляются без изменения существующего кода. + +### 3.3 Observer +Паттерн Observer используется для обновления консольного интерфейса при изменении состояния программы: загрузка лабиринта, поиск пути, движение игрока. + +Преимущества: +- вывод отделён от логики; +- можно заменить консольный интерфейс на графический без изменения поискового кода; +- упрощается расширение визуализации. + +### 3.4 Command +Паттерн Command используется для пошагового перемещения игрока и отмены последнего хода. + +Преимущества: +- каждое действие оформляется как отдельный объект; +- легко реализовать undo; +- история ходов хранится отдельно от логики перемещения. + +## 4.

Позволяет быстро проверять, является ли клетка проходимой. + +### Maze +Содержит двумерную карту клеток, размер лабиринта, а также ссылки на старт и выход. Даёт доступ к соседним клеткам по четырём направлениям. + +### TextFileMazeBuilder +Читает текстовый файл, создаёт объекты `Cell`, определяет старт и выход, затем возвращает готовый `Maze`. + +### BFSStrategy +Ищет кратчайший путь по числу шагов. Подходит для случая, когда все переходы одинаковой стоимости. + +### DFSStrategy +Быстро исследует пространство, но не гарантирует кратчайший путь. Полезен как сравнительный алгоритм. + +### AStarStrategy +Использует эвристику Манхэттенского расстояния. Обычно посещает меньше клеток, чем BFS, если эвристика удачно направляет поиск к цели. + +### MazeSolver +Оркестратор, который хранит лабиринт и текущую стратегию. Вызывает поиск, измеряет время и собирает статистику. + +### SearchStats +Содержит итог поиска: время выполнения, количество посещённых клеток и длину пути. + +### ConsoleView +Реализует наблюдателя и умеет выводить лабиринт и найденный путь в консоль. + +### MoveCommand +Оформляет ход игрока как объект-команду. Поддерживает отмену последнего перемещения. + +## 6. Экспериментальная часть + +### 6.1 Подготовка тестовых лабиринтов +Для сравнения стратегий использовались следующие типы лабиринтов: +- маленький 10×10 с простым путём; +- средний 50×50 с тупиками; +- большой 100×100 со сложной структурой; +- пустой лабиринт без стен; +- лабиринт без выхода. + +### 6.2 Методика измерений +Для каждой стратегии и каждого лабиринта поиск запускался несколько раз, после чего вычислялись средние значения: +- время поиска в миллисекундах; +- количество посещённых клеток; +- длина найденного пути. + +Результаты сохранялись в CSV-файл в двух вариантах: +- сырой набор измерений; +- усреднённая таблица. + +## 7. Анализ эффективности + +### BFS +BFS гарантирует кратчайший путь по числу шагов, если все переходы имеют одинаковую стоимость. На простых и пустых лабиринтах работает стабильно и предсказуемо. Минус — может посещать много клеток, особенно на больших лабиринтах. + +### DFS +DFS может быстро найти какой-то путь, но он не обязательно будет кратчайшим. На сложных лабиринтах иногда работает быстро, но на других может уйти далеко от цели и пройти лишние области. + +### A* +A* использует эвристику и обычно показывает хороший баланс между скоростью и качеством пути. На больших и запутанных лабиринтах часто посещает меньше клеток, чем BFS, потому что поиск направлен в сторону выхода. + +### Лабиринт без пути +Если пути нет, все алгоритмы вынуждены исследовать доступную область. В этом случае длина пути равна 0, а различия между алгоритмами проявляются в количестве просмотренных клеток и времени выполнения. + +### Вывод по выбору алгоритма +- BFS стоит выбирать, когда нужен гарантированно кратчайший путь и веса переходов одинаковы. +- DFS полезен как простой и быстрый по реализации вариант, но без гарантии оптимальности. +- A* подходит для практических задач, где нужно ускорить поиск и сократить число посещённых клеток. +- При взвешенных переходах лучше использовать Дейкстру или взвешенный A*. + +## 8. Роль ООП и паттернов +ООП и паттерны сделали код более гибким и расширяемым. Благодаря этому: +- можно заменить алгоритм поиска без переписывания логики программы; +- можно добавить новый формат загрузки лабиринта; +- можно поменять способ визуализации; +- можно расширить управление игроком и добавить отмену действий. + +Без паттернов пришлось бы связывать загрузку, поиск, отображение и управление в один большой блок кода. Это усложнило бы отладку и дальнейшие изменения. + +## 9. Вывод +В ходе работы была создана расширяемая программа для поиска пути в лабиринте. Использование паттернов Builder, Strategy, Observer и Command позволило разделить обязанности между классами, упростить поддержку кода и сделать архитектуру удобной для дальнейшего развития. Эксперименты показали, что выбор алгоритма сильно зависит от типа лабиринта: BFS даёт кратчайший путь, DFS иногда быстрее в реализации, а A* чаще всего наиболее практичен на больших картах. + +## 10. Приложения +- Листинги ключевых классов. +- CSV-файлы с результатами экспериментов. +- Графики сравнений. +- Файлы с тестовыми лабиринтами. diff --git a/BolonkinNM/experiment.py

Анализ полученных данных + +### 3.1. Поведение BST при разных порядках ввода + +Двоичное дерево поиска сильно зависит от порядка поступления ключей. При случайном порядке средняя высота близка к логарифмической, что даёт отличную производительность: + +- вставка – **0.0277 с**, +- поиск – **0.00029 с** (самый быстрый среди всех структур в этом режиме). + +Однако при вставке отсортированных данных дерево вырождается в линейный список (каждый новый узел добавляется только в правое поддерево). Последствия: + +- время вставки возрастает **в 367 раз** (с 0.0277 до 10.16 с), +- поиск замедляется **в 305 раз**, +- удаление – **в 339 раз**. + +Вырожденное BST на отсортированных данных работает **медленнее даже связного списка** (вставка 10.16 с против 4.44 с, поиск 0.088 с против 0.027 с), что объясняется накладными расходами на рекурсивные вызовы и проверки. + +### 3.2. Хеш-таблица – устойчивость к порядку + +Хеш-таблица использует функцию `hash(name) % size`, которая равномерно рассеивает имена независимо от их лексикографического порядка. Поэтому результаты в двух режимах практически идентичны: + +- вставка: 0.668 с (случайный) против 0.646 с (отсортированный) – разница менее 4%, +- поиск: 0.0051 с против 0.0040 с, +- удаление: 0.0019 с против 0.0021 с. + +Небольшие расхождения находятся в пределах случайной вариации (зависит от коллизий, которые немного различаются при разном порядке вставки). Средняя сложность операций остаётся **O(1)**. + +### 3.3. Связный список – ожидаемо медленный + +Линейный список не обеспечивает прямого доступа, поэтому все операции (кроме удаления после нахождения) требуют обхода в среднем половины списка. Даже при сравнительно небольшом объёме данных (10 000 записей) времена велики: + +- вставка ≈ **4.6 с** (на два порядка хуже, чем у хеш-таблицы и BST на случайных данных), +- поиск ≈ **0.03 с** (в 6–10 раз медленнее, чем у других структур). + +Интересно, что на отсортированных данных список показывает немного лучшее время, чем на случайных. Причина: при вставке в конец отсортированного списка (имена идут в алфавитном порядке) новые узлы добавляются без поиска дубликатов? Но алгоритм `ll_insert` сначала проверяет наличие имени, проходя весь список. Поскольку все имена уникальны и не обновляются, каждый проход идёт до конца. Однако в отсортированном режиме имена добавляются в порядке возрастания, и при проверке дубликата мы проходим по уже существующим элементам, которые все меньше нового? Да, в отсортированном режиме каждое новое имя больше всех предыдущих, поэтому при поиске дубликата мы обходим весь существующий список. В случайном режиме новые имена могут встречаться раньше, и поиск останавливается раньше? Но в любом случае разница небольшая (около 6%), и в целом список остаётся медленным. + +### 3.4. Сравнение удаления + +Удаление в списке требует сначала найти элемент (O(n)), затем перелинковку. В хеш-таблице удаление сводится к удалению в коротком списке корзины (почти O(1)). В BST на случайных данных удаление очень быстрое (0.00016 с), на отсортированных – катастрофически замедляется (0.054 с). Для хеш-таблицы удаление немного быстрее, чем вставка, что естественно: при удалении не нужно создавать новый узел. + +## 4. Выводы и практические рекомендации + +Проведённое исследование наглядно демонстрирует сильные и слабые стороны каждой структуры. + +1. **Хеш-таблица** – лучший выбор для задач, где приоритетом является скорость всех операций (вставка, поиск, удаление), а порядок вывода данных не важен или может быть получен отдельной сортировкой. Стабильно высокая производительность вне зависимости от характера входных данных. В реальных проектах именно хеш-таблицы лежат в основе словарей (Python `dict`, Java `HashMap`). + +2. **Двоичное дерево поиска** – эффективно только при случайном или близком к случайному порядке поступления ключей. Даёт логарифмическую сложность и при этом позволяет получать данные в отсортированном виде за O(n) без дополнительной сортировки. Однако на реальных данных (например, заведомо отсортированных) производительность падает до O(n), что делает его непригодным без механизмов балансировки. На практике применяются сбалансированные варианты (AVL, красно-чёрные деревья). + +3. **Связный список** – не подходит для коллекций объёмом более нескольких сотен элементов из-за линейной сложности основных операций. Может использоваться только в очень специфических сценариях: очень редкий поиск, постоянные вставки/удаления в начало (но не в конец), или как строительный блок для других структур (например, для цепочек в хеш-таблице, что и было сделано в данной работе). + +### Итоговая таблица применимости + +| Критерий | Рекомендуемая структура | +|---------------------------------|---------------------------------------| +| Максимальная скорость всех операций | Хеш-таблица | +| Нужны данные в отсортированном порядке + данные поступают случайно | BST (но лучше сбалансированное) | +| Данные поступают уже отсортированными | Хеш-таблица (или балансируемое дерево) | +| Очень маленький объём (< 100 записей) | Любая, но проще список | + +В реальной разработке для телефонного справочника с большим числом записей и частыми запросами поиска оптимальным решением будет **хеш-таблица**. Если же дополнительно требуется частый вывод всего справочника по алфавиту, стоит рассмотреть сбалансированное дерево (например, встроенный в Python модуль `bisect` не даёт структуры данных, а `sortedcontainers` – сторонний). \ No newline at end of file diff --git a/BoriskovaDV/docs/report2.md b/BoriskovaDV/docs/report2.md new file mode 100644 index 00000000..b18c8291 --- /dev/null +++ b/BoriskovaDV/docs/report2.md @@ -0,0 +1,92 @@ +# Отчёт по лабораторной работе: Алгоритмы поиска пути в лабиринте + +## 1. Цель работы + +Разработка программы для загрузки лабиринта из текстового файла, реализации трёх алгоритмов поиска пути (BFS, DFS, A\*) и проведения экспериментального сравнения их эффективности на лабиринтах различной сложности. + +## 2. Структура программы + +Программа написана на Python 3 и состоит из следующих основных классов: + +- `GridPoint` – представление клетки лабиринта (координаты, проходимость, флаги старта/выхода); +- `Labyrinth` – модель лабиринта (сетка клеток, методы получения соседей); +- `TextMazeLoader` – загрузка лабиринта из файла с символами `#` (стена), `S` (старт), `E` (выход); +- `SearchAlgorithm` (и наследники `BreadthFirst`, `DepthFirst`, `AStar`) – реализация алгоритмов поиска; +- `LabyrinthSolver` – класс-оркестратор, позволяющий сменить стратегию и измеряющий время выполнения; +- `Player`, `Command`, `MoveCommand`, `InteractiveView` – для интерактивного режима с отменой ходов; +- функции `run_experiment` и `generate_plots` – для многократных запусков и построения графиков. + +## 3.

Анализ результатов + +### 6.1. Нахождение кратчайшего пути +- **BFS** и **A*** нашли оптимальные пути во всех лабиринтах, где выход существовал (длина пути совпадает для них в каждом случае). +- **DFS** в лабиринтах Medium, Large и Empty дал существенно более длинные пути (30 против 16, 68 против 36, 89 против 17), что характерно для глубинного обхода без эвристики. + +### 6.2. Время выполнения +- На малых лабиринтах все алгоритмы работают сопоставимо (0.035–0.099 мс). +- На лабиринте Large 20×20 BFS выполнился за 0.099 мс, A* – 0.165 мс (медленнее из-за сложности поддержки очереди с приоритетом), DFS – быстрее всех (0.070 мс). +- В пустом лабиринте BFS и A* обошли почти все клетки (133 и 65 посещённых соответственно), но A* за счёт эвристики посетил вдвое меньше клеток, хотя время оказалось чуть выше, чем у BFS (0.154 против 0.133 мс). Это объясняется накладными расходами на вычисление эвристики и управление кучей. + +### 6.3. Количество посещённых клеток +- **A*** показал лучшую эффективность в пустом лабиринте (65 посещённых против 133 у BFS и 161 у DFS). В лабиринтах со стенами разница не столь заметна, но A* почти всегда посещал меньше клеток, чем BFS. +- **DFS** в среднем посещает меньше клеток, чем BFS, но при этом путь часто неоптимален. +- **BFS** вынужден обходить всю область равных расстояний, поэтому посещённых клеток обычно больше. + +### 6.4. Поведение при отсутствии выхода +Все алгоритмы корректно завершились, вернув пустой путь (длина 0). В лабиринте без выхода BFS, DFS и A* посетили 25 клеток – это все доступные клетки. + +## 7. Выводы + +1. **BFS** надёжен для поиска кратчайшего пути, но может быть медленнее на больших открытых пространствах из-за широкого обхода. +2. **DFS** – самый быстрый по времени и экономный по памяти, но не гарантирует оптимальность пути. Его применение оправдано, когда любой путь подходит. +3. **A*** демонстрирует лучший баланс: находит кратчайший путь и при этом посещает меньше клеток, чем BFS. Небольшое замедление на сложных лабиринтах компенсируется меньшим числом обработанных клеток. +4. Программа успешно справляется с лабиринтами разного размера и конфигурации, включая отсутствие выхода. +5. Интерактивный режим с отменой ходов (паттерн Command) и выбором алгоритма (паттерн Strategy) реализован и работает корректно. diff --git a/BorisovMI/429.md b/BorisovMI/429.md new file mode 100644

"Структуры данных" + +## 1. Введение +В рамках работы были реализованы три структуры данных для хранения телефонного справочника: связный список, хеш-таблица и двоичное дерево поиска. Проведено экспериментальное сравнение производительности операций вставки, поиска и удаления на наборе из **10 000 записей**. Для каждой структуры тестирование выполнялось на двух вариантах входных данных: случайный порядок и отсортированный по имени. Каждый эксперимент повторялся 5 раз, результаты усреднены. + +## 2.

Анализ результатов + +### 3.1. Влияние порядка данных на BST +При вставке элементов в отсортированном порядке двоичное дерево поиска вырождается в линейный список – все новые узлы добавляются только в правое поддерево. Высота дерева становится равной количеству элементов, и сложность всех операций возрастает до **O(n)**. Эксперимент подтверждает это: +- Вставка в BST на отсортированных данных заняла **0.303 с**, что в **57 раз** больше, чем на случайных (0.00532 с). +- Время вставки на отсортированных данных даже превышает показатели связного списка (0.112 с), что объясняется дополнительными накладными расходами на рекурсивные вызовы. +- Поиск и удаление также замедлились примерно в 60 раз по сравнению со случайным режимом. + +### 3.2. Устойчивость хеш-таблицы к порядку +Хеш-таблица использует хеш-функцию, которая равномерно распределяет ключи по корзинам независимо от порядка поступления. Поэтому производительность операций практически не зависит от того, в каком порядке приходят данные: +- В случайном и отсортированном режимах времена вставки (0.0131 и 0.0156 с) и поиска (около 0.0011 с) близки. +- Небольшие колебания могут быть вызваны случайным распределением коллизий. +- Это соответствует ожидаемой средней сложности **O(1)**. + +### 3.3. Медлительность связного списка при поиске +Связный список не обеспечивает прямого доступа к элементам – для поиска необходимо просматривать узлы последовательно, что даёт сложность **O(n)**. В эксперименте: +- Время поиска в списке (~0.007 с) на порядок больше, чем в хеш-таблице (0.0011 с) и BST на случайных данных (0.00037 с). +- При увеличении объёма данных эта разница будет только расти. +- Вставка в список также относительно медленна (0.11 с), так как требует прохода до конца (хотя обновление существующего имени выполняется быстрее, но в тесте все имена уникальны, поэтому каждая вставка проходит весь список). + +### 3.4. Сравнение удаления +- **Связный список**: удаление требует сначала найти элемент (O(n)), затем переставить ссылки (O(1)). Время удаления (0.00065 с) близко ко времени поиска, что логично. +- **Хеш-таблица**: удаление выполняется за O(1) в среднем – сначала определяется корзина, затем из короткого списка удаляется элемент. Время удаления (0.000085–0.00014 с) значительно меньше, чем в списке. +- **BST**: на случайных данных удаление очень быстрое (0.000053 с) благодаря логарифмической высоте. На отсортированных данных время возрастает до 0.00268 с (в 50 раз), что отражает деградацию до O(n). + +## 4. Выводы и рекомендации по выбору структуры + +На основе полученных результатов можно сформулировать следующие рекомендации: + +- **Хеш-таблица** – оптимальный выбор, если требуется максимальная скорость поиска, вставки и удаления, а порядок хранения не важен. Примеры: реализация словарей, кэшей, индексов по ключу. В эксперименте хеш-таблица показала стабильно высокую производительность во всех режимах. + +- **Двоичное дерево поиска** – следует применять, когда необходимо получать данные в отсортированном порядке (например, вывод телефонного справочника по алфавиту). Однако важно учитывать, что при поступлении отсортированных данных дерево вырождается, и производительность резко падает. В таких случаях лучше использовать сбалансированные деревья (AVL, красно-чёрные). В эксперименте BST на случайных данных показал отличные результаты, близкие к хеш-таблице, а на отсортированных – стал самым медленным. + +- **Связный список** – практически непригоден для больших объёмов данных из-за линейной сложности основных операций. Может использоваться лишь для очень маленьких коллекций, при частых вставках в начало списка (здесь не рассматривалось) или в учебных целях. + +Таким образом, для реальных задач чаще всего выбирают хеш-таблицы или сбалансированные деревья в зависимости от требований к упорядоченности данных. + + +I use arch BTW diff --git a/BudakovIS/docs/report_2-nd-exersize.md b/BudakovIS/docs/report_2-nd-exersize.md new file mode 100644 index 00000000..7977a5c7 --- /dev/null +++ b/BudakovIS/docs/report_2-nd-exersize.md @@ -0,0 +1,158 @@ +# Отчет по лабораторной работе: Поиск выхода из лабиринта + +## 1.

BFS гарантирует нахождение кратчайшего пути, но требует больше памяти и времени на больших лабиринтах. В экспериментах BFS показал стабильные результаты, находя оптимальные пути длиной 14, 12, 5 и 15 шагов соответственно. + +2. DFS является самым быстрым по времени (0.018-0.069 мс) и самым экономичным по памяти, но не гарантирует кратчайший путь. В пустом лабиринте DFS нашел путь длиной 43 шага, в то время как оптимальный путь составляет 15 шагов. + +3. A* показывает наилучший баланс: находит кратчайший путь (как BFS) и при этом быстрее по времени на больших лабиринтах. A* посетил меньше всего клеток (9-63) по сравнению с конкурентами. + +4. В лабиринте 20x20 все алгоритмы сработали очень быстро (0.019-0.023 мс), так как путь оказался коротким (всего 5 шагов). + +5. При отсутствии пути (лабиринт maze_no_exit.txt) все алгоритмы корректно обрабатывают ситуацию и возвращают пустой список. + +### Рекомендации по выбору алгоритма + +- Для небольших лабиринтов (до 20x20) подходит любой алгоритм +- Для больших лабиринтов, где важна оптимальность пути, выбирайте A* +- Для максимальной скорости, когда путь не важен, используйте DFS +- Для лабиринтов с гарантией кратчайшего пути используйте BFS + +## 6. Заключение + +### Преимущества использованных паттернов + +Builder позволил легко реализовать загрузку лабиринтов из текстовых файлов и оставил возможность для добавления других форматов без изменения основного кода. + +Strategy сделал алгоритмы поиска взаимозаменяемыми. Добавление нового алгоритма (например, Дейкстры) потребовало бы только создания нового класса. + +Observer отделил логику отображения от логики приложения, что упростило добавление новых видов визуализации. + +Command позволил реализовать пошаговое управление игроком с возможностью отмены действий без усложнения класса Player. + +### Итог + +Разработанная программа демонстрирует преимущества объектно-ориентированного подхода и использования паттернов проектирования. Код является гибким, расширяемым и легко поддерживаемым. Эксперименты показали, что A* является наиболее сбалансированным алгоритмом для поиска пути в лабиринте, обеспечивая оптимальный путь при приемлемой скорости работы. diff --git a/DerbenevRY/428.md

Анализ результатов + +### 3.1. Влияние порядка данных на BST + +Двоичное дерево поиска при вставке отсортированных данных вырождается в линейный список – каждый новый узел становится правым потомком предыдущего. Высота дерева достигает \( N \), и сложность всех операций падает с \( O(\log N) \) до \( O(N) \). Эксперимент ярко это подтверждает: + +- **Вставка** на отсортированных данных заняла **8.889 с** – это в **370 раз** медленнее, чем на случайных (0.024 с). +- **Поиск** замедлился в **360 раз** (0.0807 с против 0.000222 с). +- **Удаление** замедлилось в **400 раз** (0.0489 с против 0.000122 с). + +Такой эффект делает обычное двоичное дерево непригодным для данных, поступающих в упорядоченном виде, если не применять балансировку. + +### 3.2. Стабильность хеш-таблицы + +Хеш-таблица использует хеш-функцию, которая равномерно распределяет имена по корзинам независимо от их исходного порядка. Поэтому производительность почти не меняется: + +- Вставка: ~0.055 с (случайный) и ~0.053 с (отсортированный) – разница менее 5%. +- Поиск: 0.00068 с против 0.00041 с – небольшие колебания связаны со случайными коллизиями. +- Удаление: также стабильно. + +Это соответствует теоретической сложности \( O(1) \) в среднем для всех операций. + +### 3.3. Связный список – ожидаемо медленный + +Линейный поиск и вставка в конец дают сложность \( O(N) \) для всех операций: + +- Вставка на случайных данных: **4.55 с** – почти в 200 раз медленнее, чем у хеш-таблицы. +- Поиск: **0.0316 с** – на два порядка медленнее, чем у BST на случайных данных. +- Отсортированный порядок даёт небольшой выигрыш во вставке (3.7 с), потому что при вставке в конец не нужно сравнивать имена для поиска дубликатов? На самом деле в текущей реализации при вставке всё равно выполняется проход по всем элементам для проверки существования имени, поэтому разница не принципиальна. + +Связный список абсолютно не подходит для больших объёмов данных, если нужен частый поиск. + +### 3.4. Сравнение удаления + +- **Связный список** – удаление требует линейного поиска, время ~0.018 с (сопоставимо с поиском). +- **Хеш-таблица** – удаление за \( O(1) \) в среднем: ~0.0002 с. +- **BST** на случайных данных – очень быстрое удаление (~0.00012 с), но на отсортированных падает до 0.049 с (из-за вырождения). + +--- + +## 4. Выводы и практические рекомендации + +На основе полученных результатов можно сформулировать следующие правила выбора структуры данных: + +| Если важно... | Рекомендуемая структура | +|------------------------------------------------|---------------------------------------------| +| Максимальная скорость поиска, вставки, удаления и порядок данных заранее неизвестен | **Хеш-таблица** (с хорошей хеш-функцией) | +| Нужно часто выводить данные в отсортированном виде, и данные поступают в случайном порядке | **Сбалансированное дерево** (AVL, красно-чёрное) | +| Данные поступают в отсортированном виде, но нужен отсортированный вывод | **Плохое обычное BST** использовать нельзя – только после перемешивания или с балансировкой | +| Объём данных очень мал (< 100 записей) и простота реализации важнее скорости | **Связный список** | + +**Конкретные выводы по эксперименту:** + +1. **Хеш-таблица** показала стабильно высокую производительность во всех режимах. Это лучший выбор для телефонного справочника, если не требуется выдача записей в алфавитном порядке (в задании `list_all()` сортирует отдельно, что приемлемо). +2. **Двоичное дерево поиска** на случайных данных работает почти так же быстро, как хеш-таблица, но полностью деградирует на отсортированных. Это демонстрирует необходимость использования самобалансирующихся деревьев в реальных приложениях (например, `dict` в Python внутри реализован как хеш-таблица, а `SortedDict` – как дерево). +3. **Связный список** непригоден для практического использования при \( N > 1000 \) из-за линейной сложности основных операций. + +**Итог:** для телефонного справочника с типичной нагрузкой (много поисков, частые вставки) оптимальной структурой является **хеш-таблица**. Если же требуется постоянно поддерживать данные в отсортированном виде (например, для автодополнения), то следует применять **сбалансированное дерево поиска**. + +--- + +*Дата выполнения эксперимента:* 22 мая 2026 г. +*Файлы результатов:* `experiment_results.csv`, `performance_comparison.png` diff --git a/KuznetsovYuM/docs/report-2-nd.md b/KuznetsovYuM/docs/report-2-nd.md new file mode 100644 index 00000000..ec0ad8b5 --- /dev/null +++ b/KuznetsovYuM/docs/report-2-nd.md @@ -0,0 +1,79 @@ +# Лабораторная работа: Поиск выхода из лабиринта + +## 1.

Анализ результатов + +### 4.1. Лабиринты без достижимого выхода + +Для лабиринтов `Small 10×6`, `Medium 10×10` и `No exit 10×10` все алгоритмы вернули длину пути 0. Это означает, что в данных экземплярах лабиринта **нет пути от старта до выхода** (либо старт или выход заблокированы стенами, либо лабиринт не содержит корректного маршрута). При этом количество посещённых клеток (19, 31 и 27 соответственно) совпадает для всех трёх алгоритмов, что говорит о том, что каждый алгоритм обошёл все достижимые клетки, прежде чем убедиться в отсутствии пути. + +### 4.2. Лабиринт `Large 20×20` (большой запутанный) + +- **BFS** и **A*** нашли кратчайший путь длиной **33** шага. +- **DFS** нашёл более длинный путь – **39** шагов (что ожидаемо, так как DFS не гарантирует оптимальность). +- По времени BFS и DFS показали близкие значения (~0.15 мс), A* был несколько медленнее (0.269 мс) из-за накладных расходов на приоритетную очередь и вычисление эвристики. +- По количеству посещённых клеток A* значительно эффективнее: **73** против **152** (BFS) и **155** (DFS). Это подтверждает, что эвристика A* направляет поиск к цели, резко сокращая перебор. + +### 4.3. Лабиринт `Empty 15×15` (пустое поле без стен) + +- Оптимальный путь (только вправо и вниз, без диагоналей) составляет `(15-1)+(15-1) = 28` шагов. BFS и A* нашли путь длиной **29** (возможно, небольшая неоптимальность из-за порядка обхода соседей или старт/выход не в углах? Но в данных длина 29 – принимаем как факт). DFS дал очень длинный маршрут – **113** шагов. +- По времени DFS оказался самым быстрым (0.127 мс), BFS – 0.245 мс, A* – 0.532 мс. Замедление A* объясняется большим количеством клеток (225) и постоянными операциями с кучей. +- Количество посещённых клеток: BFS и A* посетили все 225 клеток (поскольку поле пустое, нужно обойти весь лабиринт, чтобы доказать оптимальность или найти путь). DFS посетил 211 клеток – он остановился, найдя (неоптимальный) путь раньше. + +### 4.4. Общие наблюдения + +- **BFS** стабильно находит кратчайший путь (там, где путь существует), но требует много памяти и посещает много клеток. +- **DFS** самый быстрый по времени на малых и средних лабиринтах, но его путь может быть далёк от оптимального (в пустом лабиринте – в 4 раза длиннее оптимального). +- **A*** является лучшим компромиссом: находит оптимальный путь (как BFS) и при этом посещает значительно меньше клеток, но платит за это несколько большим временем на сложных картах (из-за работы с приоритетной очередью). +- В лабиринтах без выхода все алгоритмы честно обходят все достижимые клетки и возвращают пустой путь. Различий в количестве посещённых клеток нет, так как достижимая область одинакова. + +## 5. Выводы + +1. **Для небольших лабиринтов** (до 10×10) разница между алгоритмами несущественна. Если путь существует, любой алгоритм справится быстро. +2. **Для больших лабиринтов с длинными коридорами** A* демонстрирует лучшую эффективность по числу посещённых клеток, что критично для ресурсоёмких приложений. +3. **Если требуется гарантированно кратчайший путь**, следует выбирать BFS или A*. BFS проще в реализации, A* быстрее находит цель. +4. **DFS** полезен только тогда, когда скорость важнее оптимальности (например, в играх с простыми противниками) или когда лабиринт заведомо не содержит длинных тупиков. +5. Разработанная программа корректно обрабатывает ситуацию отсутствия пути, что подтверждается нулевой длиной маршрута в соответствующих тестах. + +## 6. Итог + +Приложение реализует полный цикл работы с лабиринтами: загрузку, визуализацию, поиск пути тремя различными алгоритмами, сбор статистики и построение графиков. Эксперименты подтвердили теоретические свойства алгоритмов: BFS и A* находят кратчайший путь, DFS – быстр, но неоптимален, а A* существенно сокращает количество просматриваемых клеток. Полученные результаты согласуются с классическими оценками сложности алгоритмов поиска на графах. diff --git a/LarikovaAA/428b.md b/LarikovaAA/428b.md new file mode 100644 index 00000000..e69de29b diff --git a/LukovnikovDE/428.md b/LukovnikovDE/428.md new file mode 100644 index 00000000..e69de29b diff --git a/MalkinMV/428b.md b/MalkinMV/428b.md new file mode 100644 index 00000000..225a97e5 --- /dev/null +++ b/MalkinMV/428b.md @@ -0,0 +1 @@ +428b diff --git a/MarkinAM/1/delete_chart.svg b/MarkinAM/1/delete_chart.svg new file mode 100644 index 00000000..f7deca6d --- /dev/null +++ b/MarkinAM/1/delete_chart.svg @@ -0,0 +1,1291 @@ + + + + + + + + 2026-05-23T09:42:52.742816 + image/svg+xml + + + Matplotlib v3.10.0, https://matplotlib.org/ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + diff --git a/MarkinAM/1/docs/report.md b/MarkinAM/1/docs/report.md new file mode 100644 index 00000000..76c40e80 --- /dev/null +++ b/MarkinAM/1/docs/report.md @@ -0,0 +1,74 @@ + +# Отчёт по лабораторной работе + +## Цель работы + +Реализовать три структуры данных «с нуля» (связный список, хеш-таблица, двоичное дерево поиска), применить их для хранения записей телефонного справочника и экспериментально сравнить производительность основных операций. + +**Структуры данных:** +- Связный список (LinkedList) +- Хеш-таблица (HashTable) +- Двоичное дерево поиска (BST) + + +## Параметры эксперимента + +- Количество записей: 10000 +- Количество повторов каждого теста: 5 +- Размер хеш-таблицы: 1000 корзин + +### 1.

Несмотря на чуть большую константа в асимптотике по сравнению с хеш-таблицей, оно позволяет эффективно получать отсортированные данные, находить минимальный/максимальный элемент или элементы в заданном диапазоне. +#### Связный список в чистом виде для решения подобных задач сегодня практически не применяется из-за низкой эффективности поиска. diff --git a/MarkinAM/1/find_chart.svg

При случайных уникальных именах вставка идёт в начало O(1), но **поиск** всегда линейный. + +**Вывод:** связный список плох для частых поисков в большой коллекции, но хорош как строительный блок (используется в бакетах хеш-таблицы). + +### 2.

Высота дерева становится O(n) вместо O(log n). Поиск и удаление тоже деградируют до O(n). + +### 4. Сравнение операции delete + +При случайных данных BST удаляет за **~0.0001 с** (log n).

BFS — оптимальный путь, высокое покрытие + +BFS всегда находит **кратчайший путь** (15 шагов на small, 95 на medium).

DFS — быстрый по времени, длинный путь + +DFS посещает меньше клеток в среднем, но путь получается значительно длиннее: 185 шагов против 95 у BFS на том же лабиринте. На открытом лабиринте без стен DFS нашёл путь в **1129 шагов** вместо 95 у BFS — наглядная демонстрация того, что DFS не гарантирует оптимальности. + +### 3. A* — меньше всего посещённых клеток + +На medium_50x50 A* посетил всего **588 клеток** против 1639 у BFS — в 2.8 раза меньше. При этом путь тот же оптимальный (95 шагов). Манхэттенская эвристика направляет поиск к выходу и отсекает лишние направления. + +На открытом лабиринте без стен A* тратит больше времени (5.566 мс против 3.296 мс у BFS) — эвристика считается для каждого узла, а без препятствий нет выигрыша в отсечении. + +### 4. Большой лабиринт (100×100) — путь не найден + +Все три алгоритма исчерпали все 6564 доступные клетки и не нашли пути. При плотности стен 30% на данном лабиринте выход оказался недостижим.

Задача разработки телефонного справочника является классическим примером, требующим баланса между скоростью вставки новых записей, поиском по ключу и эффективным удалением. + + В рамках данной работы исследуются три фундаментальные структуры данных, реализованные «с нуля» в процедурной парадигме программирования на языке Python: + \begin{itemize} + \item \textbf{Связный список (Linked List)} --- динамическая структура, позволяющая оценить базовые механизмы управления указателями и демонстрирующая линейную сложность операций $O(n)$. + \item \textbf{Хеш-таблица (Hash Table)} --- ассоциативный массив, использующий хеширование для обеспечения прямого доступа к данным. Реализация позволяет изучить методы разрешения коллизий и преимущества константной сложности $O(1)$. + \item \textbf{Двоичное дерево поиска (BST)} --- иерархическая структура, обеспечивающая логарифмическую скорость доступа $O(\log n)$ и поддерживающая упорядоченность данных «из коробки». + \end{itemize} + + \textbf{Цель работы:} Изучить внутренние алгоритмы работы перечисленных структур, реализовать их без использования встроенных высокоуровневых контейнеров и экспериментально подтвердить теоретические оценки временной сложности на случайных и отсортированных наборах данных. + + \section{Реализация структур данных} + \subsection{Связный список} + % Здесь опишите логику ll_insert, ll_find и ll_delete + \subsection{Хеш-таблица} + % Опишите хеш-функцию и метод цепочек + \subsection{Двоичное дерево поиска} + % Опишите рекурсивные алгоритмы и проблему деградации + + \section{Методика эксперимента} + Замеры производились для наборов данных объемом $N=500, 1000, 2000, 5000, 10000$ элементов. Использовались два сценария: перемешанные (\textit{shuffled}) и отсортированные по алфавиту (\textit{sorted}) записи. Каждая операция выполнялась 5 раз с последующим вычислением среднего арифметического значения с помощью функции \texttt{time.perf\_counter()}. + + \section{Результаты и анализ} + Было проведено серию опытов для $N$ от 500 до 10000. + \subsection*{1.

Рост времени в 100 раз при увеличении объема данных в 10 раз четко указывает на квадратичную сложность $O(n^2)$ для процесса заполнения всей структуры. Дерево выродилось в линейный список, и поиск места вставки стал занимать $O(n)$ вместо ожидаемого $O(\log n)$. + \item \textbf{Эффективность на перемешанных данных:} На \texttt{shuffled} данных вставка 10000 элементов заняла всего \textbf{0.031с}. Это подтверждает логарифмическую сложность $O(\log n)$ для операций в дереве при случайном распределении ключей. + \end{itemize} + + \subsection*{2. Хеш-таблица: Стабильность и скорость} + + \begin{figure}[H] + \centering + \includegraphics[scale=0.7]{plots/Thasht1.eps} + \end{figure} + + \begin{figure}[H] + \centering + \includegraphics[scale=0.7]{plots/Thasht2.eps} + \end{figure} + + \begin{itemize} + \item \textbf{Чувствительность к порядку:} Хеш-таблица показала идентичные результаты как на \texttt{shuffled}, так и на \texttt{sorted} данных (около \textbf{0.165с} -- \textbf{0.167с} для 10000 вставок). Это объясняется тем, что хеш-функция распределяет ключи по бакетам независимо от их исходного порядка, предотвращая деградацию структуры. + \item \textbf{Превосходство:} На больших объемах хеш-таблица оказалась самой быстрой структурой для поиска и удаления ($\approx 0.001$с при $N=10000$), что подтверждает теоретическую среднюю сложность $O(1)$. + \item \textbf{Замечание:} Так как реализация использует списки для разрешения коллизий со вставкой в конец, при заполнении таблицы наблюдается рост времени вставки, стремящийся к квадратичному, однако абсолютные значения остаются на порядки ниже, чем у выродившегося BST. + \end{itemize} + \subsection*{3. Связный список: Линейная зависимость} + \begin{figure}[H] + \centering + \includegraphics[scale=0.7]{plots/Tlinklist1.eps} + \end{figure} + + \begin{figure}[H] + \centering + \includegraphics[scale=0.7]{plots/Tlinklist2.eps} + \end{figure} + + \begin{itemize} + \item \textbf{Поиск и удаление:} Связный список показал худшие результаты среди всех структур на случайных данных. Время поиска при 10000 элементах (\textbf{0.029с}) значительно медленнее, чем у BST на перемешанных данных (\textbf{0.0002с}). Это подтверждает линейную сложность $O(n)$. + \item \textbf{Вставка:} Вставка (вероятно, в конец или с сохранением порядка) дает $O(n^2)$ при заполнении (\textbf{2.83с} -- \textbf{3.00с} на 10000 эл.). Характер роста времени при переходе от $N=5000$ (\textbf{0.71с}) к $N=10000$ подтверждает квадратичную зависимость. + \end{itemize} + + \subsection*{Вывод: выбор структуры данных} + \begin{enumerate} + \item \textbf{Хеш-таблица} — наиболее универсальный выбор. Она обеспечивает стабильное $O(1)$ для поиска и не зависит от порядка входящих данных. + \item \textbf{BST} — крайне эффективен ($O(\log n)$) при случайном распределении данных, но без механизмов самобалансировки критически уязвим к отсортированным входным последовательностям, замедляясь до уровня списка. + \item \textbf{Связный список} — продемонстрировал самую низкую производительность на операциях поиска и массовой вставки. Его использование оправдано только в специфических сценариях (например, реализация стека), где работа ведется исключительно с головой списка за $O(1)$. + \end{enumerate} + + + \subsection*{Сводная

В ходе работы необходимо применить минимум 3 паттерна проектирования из списка GoF, обосновать их выбор и продемонстрировать преимущества такой архитектуры. + + + \section{Описание задачи и выбранных паттернов} + + + Используемые Паттерны: + \begin{itemize} + + \item Strategy (Стратегия) \textemdash \ это поведенческий паттерн проектирования, который определяет семейство схожих алгоритмов и помещает каждый из них в собственный класс, после чего алгоритмы можно взаимозаменять прямо во время исполнения программы. Выбран, так как в данной лабораторной работе используются несколько алгоритмов, выполняющих одно и то же действие \ \textemdash \ обход графа. + + \item Builder (строитель) \textemdash \ абстрактный класс/интерфейс, который определяет все этапы, необходимые для производства сложного объекта-продукта. Позволяет отделить построение сложного объекта от его представления, создает сложные объекты, используя простые объекты и поэтапный подход. Выбран для изоляции сложного процесса парсинга текстовоо файла. + + \item Observer (Наблюдатель) \ \textemdash \ это поведенческий паттерн проектирования, который создаёт механизм подписки, позволяющий одним объектам следить и реагировать на события, происходящие в других объектах. Выбран для отделения логики приложения от вывода на экран (принцип MVC). Класс ConsoleView подписывается на события GameController и перерисовывает карту только тогда, когда игрок перемещается или путь найден. + + \end{itemize} + + + + \section{Диаграмма классов} + + \begin{figure}[H] + \centering + \includegraphics[scale=0.06]{plan.png} + \end{figure} + + + \section{Листиги Классов} + \subsection{Maze Solver} + + \begin{lstlisting} + import time + from Maze import Maze + from strategy import PathFindingStrategy + + class MazeSolver: + def __init__(self, maze: Maze, strategy: PathFindingStrategy): + self._maze = maze + self._strategy = strategy + self._observers = [] + + def addObserver(self, observer): + """Регистрация нового наблюдателя (например, ConsoleView)""" + self._observers.append(observer) + + def notify(self, event): + """Уведомление всех подписчиков о событии""" + for observer in self._observers: + observer.update(event) + + def setStrategy(self, strategy): + self._strategy = strategy + + def solve(self): + + if not self._maze or not self._strategy: + raise ValueError("Не задан лабиринт или стратегия поиска!") + + start_time = time.perf_counter() + + path, visited_count = self._strategy.findPath( + self._maze, self._maze.start, self._maze.exit) + + end_time = time.perf_counter() + + execution_time_ms = (end_time -

Также Дейкстра несколько медленнее из за дополнительных расчетов на сортировку стоимостей. + + Самым лучшим по скорости стал алгоритм А*. Он в среднем 3-4 раза быстрее поиска в ширину, так как на каждом шаге он выбирает самого оптимального соседа для каждого узла, а поиск в ширину проверяет всех соседей. + + В разработанной рекурсивной стратегии DFS метрика посещенных клеток совпадает с длиной пути, так как алгоритм фиксирует состояние успешно развернутого стека вызовов в момент достижения целевой точки. Все тупиковые ветви, из которых рекурсия вышла до момента нахождения exit, отсекаются архитектурой возврата флага True, что демонстрирует специфику работы рекурсивного бэктрекинга в Python + + + \section{Выводы по ООП} + + В ходе выполнения лабораторной работы была спроектирована и реализована объектно-ориентированная система поиска пути в лабиринтах. Применение принципов ООП и паттернов проектирования GoF позволило полностью разделить зоны ответственности классов (принцип Single Responsibility) и обеспечить высокий уровень гибкости и расширяемости приложения. + + 1. Как паттерны помогли сделать код гибким и расширяемым + \begin{itemize} + \item Разделение логики построения и представления (Паттерн Builder): + Процесс создания лабиринта инкапсулирован внутри класса TextFileMazeBuilder. Сам лабиринт (Maze) и алгоритмы поиска никак не завязаны на формат хранения данных. Если в будущем потребуется сменить текстовый формат .txt на структуру .json достаточно будет создать нового строителя, реализующего интерфейс MazeBuilder. + + \item Изоляция и динамическая смена алгоритмов (Паттерн Strategy): + Каждый алгоритм обхода графа вынесен в отдельный класс-стратегию с единым интерфейсом PathfindingStrategy. Класс-оркестратор MazeSolver работает исключительно с абстракцией. + + \item Использование Observer позволило отделить вычислительную составляющую от графической. Maze SOlver никак не учитывает где и как будут отображаться данные, он только отдает сигнал о событиях. Это позволяет если нужно изменить графический инт6ерфейс. + \end{itemize} + + + + +\end{document} \ No newline at end of file diff --git a/ProninVV/task-2-oop/report/plan.png b/ProninVV/task-2-oop/report/plan.png new file mode 100644 index 00000000..09a03f7c Binary files /dev/null and b/ProninVV/task-2-oop/report/plan.png differ diff --git a/ProninVV/task-2-oop/report/preambule.tex b/ProninVV/task-2-oop/report/preambule.tex new file mode 100644 index 00000000..f193c693 --- /dev/null +++ b/ProninVV/task-2-oop/report/preambule.tex @@ -0,0 +1,83 @@ +%\documentclass[a4paper, 12pt]{article} +\documentclass[a4paper, 14pt]{extarticle} + +\usepackage[english, russian]{babel} +\usepackage[T2A]{fontenc} +\usepackage[utf8]{inputenc} +\usepackage{comment} + + +\usepackage{fontspec} +\setmainfont{Times New Roman} + +\usepackage{amsmath} +\usepackage{amssymb} + +\usepackage{geometry} +\usepackage{titleps} +\usepackage{graphicx} +\DeclareGraphicsExtensions{.pdf, .jpg} +\usepackage{wrapfig} + + +\usepackage{indentfirst} + + +\geometry{top=20mm} +\geometry{bottom=25mm} +\geometry{left=30mm} +\geometry{right=10mm} + +\usepackage{float} +\usepackage{wrapfig} + +\newpagestyle{main}{ + \setheadrule{0.4pt} + \sethead{ННГУ им Н.И.

Вставка замедлилась до **10.15 секунды** – это в 406 раз медленнее, чем на случайных данных, и даже медленнее, чем у связного списка (в 2.3 раза). Поиск вырос до **0.091 секунды** (в 380 раз медленнее), удаление – до **0.057 секунды** (в 335 раз медленнее). Это классический пример деградации BST при упорядоченных входных данных. + +## Анализ результатов + +### Как порядок входных данных влияет на скорость вставки в BST + +Эксперимент наглядно демонстрирует проблему наивной реализации двоичного дерева поиска. На случайных данных дерево остаётся достаточно сбалансированным, и операции выполняются за логарифмическое время (O(log n)). Однако на отсортированных данных каждый новый элемент становится самым большим и добавляется только в правую ветку. В результате дерево превращается в односвязный список высотой 10 000 узлов, а сложность всех операций деградирует до линейной O(n). Это подтверждается цифрами: время вставки выросло с 0.025 до 10.15 секунд – разница в 406 раз. + +### Почему хеш‑таблица почти не чувствительна к порядку + +Хеш‑функция распределяет ключи по корзинам независимо от того, в каком порядке они поступают. «User_00001» и «User_10000» с равной вероятностью могут попасть в любую из 10 корзин. Поэтому порядок ввода не влияет на длину цепочек в каждой корзине. Результаты подтверждают это: в случайном и отсортированном режимах время выполнения операций отличается незначительно (менее 10%). + +### Почему связный список всегда медленен при поиске + +Связный список не имеет индексов или другой структуры для ускорения доступа. Чтобы найти элемент, нужно в худшем случае пройти все 10 000 узлов. Поэтому поиск занимает ~0.027 секунды независимо от того, как расположены данные. Вставка тоже требует прохода до конца списка, что даёт ~4.4 секунды на 10 000 элементов. + +### Как удаление работает в каждой структуре + +Удаление тесно связано с поиском, потому что сначала нужно найти удаляемый элемент. Поэтому время удаления коррелирует со временем поиска: + +- В связном списке удаление занимает ~0.012 секунды – примерно половину времени поиска (0.027 с), так как операция перелинковки дёшева. +- В хеш‑таблице удаление (~0.0016 с) близко ко времени поиска (~0.004 с), опять же с поправкой на перелинковку в списке корзины. +- В BST на случайных данных удаление (~0.00017 с) даже быстрее поиска (~0.00024 с) из-за особенностей рекурсивной реализации. +- В BST на отсортированных данных удаление (~0.057 с) занимает примерно половину времени поиска (~0.091 с) – та же закономерность, что и у списка, потому что вырожденное дерево ведёт себя как список. + +## Выводы + +**Какую структуру и для каких задач стоит выбирать в реальной жизни?** + +1. **Хеш‑таблица** – оптимальный выбор для подавляющего большинства сценариев, где нужен быстрый доступ по ключу (словари, кэши, индексы в базах данных). Она стабильна, предсказуема и не зависит от порядка данных. В моём эксперименте она уступила BST на случайных данных, но выиграла у BST на отсортированных и оказалась намного быстрее связного списка. Главный минус – отсутствие естественного порядка при обходе. + +2. **Сбалансированное дерево** (AVL или красно-чёрное) – выбор, когда нужны оба свойства: быстрый доступ (O(log n)) и возможность получать данные в отсортированном порядке без дополнительной сортировки. Обычный BST (как в моей реализации) **использовать не стоит**, если нельзя гарантировать случайный порядок входных данных. Деградация на упорядоченных данных делает его непригодным для реальных систем. + +3. **Связный список** – практически бесполезен для хранения больших объёмов данных. Единственное оправданное применение – очень маленькие коллекции (до сотни элементов), реализация очередей/стеков или учебные цели. + +**Рекомендация**: если нужен только быстрый доступ по ключу – берите хеш-таблицу. Если нужен отсортированный вывод и вы готовы пожертвовать небольшой долей производительности – используйте сбалансированное дерево. От наивного BST и связного списка в реальных проектах лучше отказаться. + +**Ключевой вывод эксперимента**: порядок поступления данных критически важен для производительности BST (разница в 400 раз между случайными и отсортированными данными), но почти не влияет на хеш-таблицу и связный список (хотя последний всегда медленный). diff --git a/SavelevMI/docs/report-2.md b/SavelevMI/docs/report-2.md new file mode 100644 index 00000000..577fe18c --- /dev/null +++ b/SavelevMI/docs/report-2.md @@ -0,0 +1,66 @@ +# Отчёт по лабораторной работе №2 «Поиск выхода из лабиринта» + +## Цель работы + +Разработать программу для поиска выхода из лабиринта с возможностью выбора алгоритма (BFS, DFS, A*), визуализацией и экспериментальным сравнением.

работы было установлено, что производительность каждой из трёх реализованных структур данных существенно зависит от их внутреннего устройства, а также от характера и порядка входных данных. + +Двоичное дерево поиска (BST) демонстрирует высокую скорость обработки при случайном порядке поступления записей. Однако при подаче данных в отсортированном виде дерево вырождается в линейную структуру, что приводит к значительному увеличению времени выполнения операций вставки и удаления – фактически до уровня связного списка. + +Хеш-таблица практически не чувствительна к порядку входных данных, поскольку доступ к элементам осуществляется через хеш-функцию, равномерно распределяющую ключи по бакетам. Благодаря этому она показала наилучшие результаты при выполнении операций поиска и вставки. +Связный список ожидаемо оказался самой медленной структурой для поиска, так как данная операция требует последовательного перебора элементов. + +Операция удаления также имеет свои особенности. В связном списке и BST удалению всегда предшествует поиск удаляемого элемента. В хеш-таблице же удаление выполняется быстрее за счёт прямого доступа к соответствующему бакету через хеш-функцию. + + + +Исходя из полученных результатов, можно сформулировать следующие рекомендации по выбору структуры данных: + +**Хеш-таблица** оптимальна для задач с частыми операциями поиска и вставки данных. Наиболее подходит для реализации телефонного справочника, словарей и кэшей. +**Двоичное дерево поиска** целесообразно использовать в тех случаях, когда требуется хранить данные в отсортированном виде, а также когда порядок поступления записей близок к случайному (либо применяются механизмы балансировки). +**Связный список** сохраняет свою актуальность в более простых задачах, где структура данных часто изменяется, а требования к скорости поиска не являются критическими. + +## Количественные результаты + +Параметры эксперимента: N = 3000 записей. + +| Операция | LinkedList | HashTable | BST (random) | BST (sorted) | +|----------|------------|-----------|--------------|---------------| +| Вставка | 0.0235 с | 0.0012 с | 0.0057 с | 0.0457 с | +| Поиск | 0.0200 с | 0.0010 с | 0.0023 с | 0.0388 с | +| Удаление | 0.0123 с | 0.0012 с | 0.0035 с | 0.0412 с | + +## Заключение + +Проведённое исследование подтверждает теоретические оценки сложности рассматриваемых структур данных.

Разница в производительности становится заметна только на больших размерах. + +2. **На больших лабиринтах** A* посещает меньше всего клеток благодаря эвристике. Это делает его предпочтительным для задач, где важна экономия памяти и времени. + +3. **Когда нужен кратчайший путь** — выбирайте BFS или A*.

Методика + +* Генерируем `N = 10 000` записей вида `("User_00000", "555-0000000")` и т.д. +* Два режима ввода: **shuffled** (случайный) и **sorted** (отсортированный по имени). +* Каждое испытание повторяется **5 раз**, в CSV сохраняем все 5 значений + и среднее. +* На каждом испытании: + 1. строим структуру заново; + 2. вставляем все N записей - замеряем время; + 3. ищем 100 случайных существующих имён + 10 несуществующих (всего 110 вызовов); + 4. удаляем 50 случайных имён. + +Замер - `time.perf_counter()`.

Анализ + +### 4.1. Почему связный список такой медленный на вставке + +Мой `ll_insert` идёт до конца списка, чтобы потом обновить узел, если он уже +есть. На N‑м элементе он совершает уже N шагов. Суммарно - около N**2/2 +операций. На N = 10 000 это даёт ~50 миллионов проходов по узлам - отсюда +и ~4 секунды. + +Если бы мы вставляли **в начало** (за O(1)), общая вставка стала бы линейной, +но тогда: +* возможны дубликаты (обновление пропускается); +* для совместимости с двумя другими структурами всё равно понадобился бы поиск. + +Поиск и удаление быстрее: 110 поисков ≈ 35 мс, потому что в среднем ищем +N/2 шагов и таких запросов всего 110. Сложность каждой операции - O(N), +но запросов мало. + +### 4.2. Почему хеш-таблица почти не зависит от порядка + +Хеш-функция превращает имя в индекс бакета. Сами имена `User_00001`, +`User_00002`, … равномерно распределяются по 2 048 бакетам, поэтому в каждом +бакете лежит в среднем ≈ 5 элементов. Все три операции работают за ~O(1). + +Порядок входных данных не имеет значения, потому что `hash(name)` от него не +зависит. На графике видно: shuffled и sorted столбцы у HashTable одинаковой +высоты. + +### 4.3. Почему BST деградирует на отсортированном входе + +Когда имена приходят в алфавитном порядке, каждый новый ключ всегда больше +предыдущего, поэтому он идёт в правое поддерево. Дерево превращается +в правый «костыль» - фактически в односвязный список. Сложность вставки - +O(N**2), поиска и удаления - O(N). + +На графике `bst_degradation.png` это видно очень ярко: даже при **в 5 раз +меньшем N (2 000 вместо 10 000)** все операции у sorted BST занимают +в 5–10 раз больше времени, чем у shuffled BST. + +Это известная слабость наивного BST. В реальном коде её решают +**самобалансирующимися деревьями** (AVL, красно-чёрные, B-деревья), +которые гарантируют глубину O(log n) даже на отсортированном входе. + +### 4.4. Удаление + +* В связном списке удаление - это пробежка до нужного узла + переключение + ссылок. На 50 запросах суммарно ~14 мс при N = 10 000. +* В хеш-таблице удаление - это пробежка по бакету (короткий список), почти O(1): + всего 0.038 мс на 50 удалений. +* В BST стандартное удаление: если у узла двое детей, заменяем его на минимум + правого поддерева и рекурсивно удаляем его. На случайном дереве - O(log n) + на удаление; на отсортированном - O(N). + +## 5. Что выбирать в реальной жизни + +| Сценарий | Лучший выбор | Почему | +| --- | --- | --- | +| Частые `insert`/`find`/`delete`, порядок не нужен | **Хеш-таблица** | O(1) на всё | +| Нужно много раз получать **отсортированный** список | **BST** (с балансировкой) | in‑order обход - это и есть сортировка, O(N) | +| Очень мало данных или редкие операции; нужна простота | **Связный список** | минимум кода, O(N) - приемлемо | +| Нужны диапазонные запросы («все имена от 'A' до 'D'») | **BST/сбалансированное** | хеш-таблица их не умеет | +| Гарантированная производительность на любых данных | **Хеш-таблица или AVL/RB-tree**, но **не наивное BST** | наивное BST уязвимо к отсортированному входу | + +Хеш-таблица в стандартной библиотеке Python - это и есть встроенный `dict`, +которым стоит пользоваться по умолчанию для пар «ключ → значение». +Понимать «руками» связный список и BST полезно, чтобы знать, что лежит +под капотом более сложных контейнеров и понимать, +когда их применять (например, `OrderedDict`, `sortedcontainers.SortedDict`, +индексы в БД и т. д.). diff --git a/SobolevNS/docs/report_02.md b/SobolevNS/docs/report_02.md new file mode 100644 index 00000000..9fd4f531 --- /dev/null +++ b/SobolevNS/docs/report_02.md @@ -0,0 +1,364 @@ +# Отчёт по заданию 2.

Паттерны и их обоснование + +### 3.1. Builder - `TextFileMazeBuilder` + +**Что делает.** Принимает имя файла, читает его, проверяет символы, ставит +координаты, создаёт `Cell`-объекты, находит `S` и `E`, валидирует +(ровно один старт и один выход) и возвращает готовый `Maze`. + +**Зачем нужен.** Конструирование лабиринта - это многошаговый процесс: +парсинг + валидация + расстановка флагов + поддержка взвешенных клеток +(`,` песок, `~` болото, `.` асфальт). Если положить всё это в конструктор +`Maze`, класс получится «толстым» и неудобным для расширения. + +**Что даёт.** Чтобы добавить новый формат (например, JSON или бинарный), +достаточно реализовать ещё один класс с тем же интерфейсом +`MazeBuilder.build_from_file`. Остальной код не меняется. + +### 3.2. Strategy - `PathFindingStrategy` + +**Что делает.** Объявляет единый интерфейс `find_path(maze, start, exit_)`. +Имеет четыре реализации: `BFSStrategy`, `DFSStrategy`, `AStarStrategy`, +`DijkstraStrategy`. Возвращают одинаковую структуру: +`{'path': [Cell, ...], 'visited': int}`. + +**Зачем нужен.** Все четыре алгоритма решают одну задачу, но с разными +компромиссами (скорость vs оптимальность vs учёт весов). Strategy позволяет +переключать их в рантайме одной строкой: + +```python +solver.set_strategy(AStarStrategy()) +``` + +без вмешательства в код решателя или модели лабиринта. + +**Что даёт.** Чтобы добавить, скажем, **двунаправленный BFS**, нужно лишь +написать новый класс - ни `MazeSolver`, ни `Maze` ничего не узнают +о нововведении. + +### 3.3. Observer - `MazeSolver` уведомляет `ConsoleView` + +**Что делает.** `MazeSolver` хранит список наблюдателей и шлёт им события: +`maze_loaded`, `search_start`, `search_end`, `path_found`, `no_path`. +`ConsoleView` подписывается и пишет в консоль. + +**Зачем нужен.** Решатель не должен знать, _кто_ и _как_ показывает +лабиринт пользователю. Можно подключить (или отключить) сразу несколько +наблюдателей - например, `ConsoleView` для отладки и `CSVLogger` +для эксперимента - не меняя `MazeSolver`. + +### 3.4. Command - `MoveCommand` с `undo` через `CommandHistory` + +**Что делает.** `MoveCommand` инкапсулирует один шаг игрока: сохраняет +предыдущую позицию, перемещает игрока в новое место. Метод `undo` +возвращает игрока обратно. `CommandHistory` ведёт стек выполненных команд +(общий undo). + +**Зачем нужен.** Ручное прохождение лабиринта = последовательность шагов, +каждый из которых должен быть откатываемым.

Анализ результатов + +### 6.1. На «обычных» перфектных лабиринтах путь единственный + +В лабиринтах, построенных DFS-карвером (`medium_51x51`, `large_101x101`, +`weighted_31x31`), между любыми двумя клетками существует **ровно один путь**. +Поэтому все четыре алгоритма находят его одинаковой длины (353, 1265, 265). +Различаются только время и **число посещённых клеток** - это и есть мера +«работы» алгоритма. + +* **DFS** - самый быстрый и обходит меньше всего клеток. Ему «везёт»: на + перфектном лабиринте он не возвращается, пока не упрётся в тупик. +* **BFS** - обходит чуть больше, потому что развивает фронт во всех направлениях. +* **A\*** и **Dijkstra** дороже по времени из-за `heapq`, но A\* экономит + посещения благодаря эвристике (на large_101x101: 1831 у A\* vs 2143 у BFS). + +### 6.2. На пустом лабиринте - главная разница между BFS/A\*/Dijkstra и DFS + +`empty_30x30` - это комната 28×28 проходимых клеток. Кратчайший путь между +противоположными углами - ровно 55 шагов. + +* BFS, A\*, Dijkstra находят его (длина = 55). +* **DFS находит путь длиной 379** - он петляет по краям комнаты, потому что + «жадно» идёт в первое попавшееся направление и никогда не возвращается, + пока не упрётся. + +Этот результат хорошо иллюстрирует: **DFS быстр, но даёт плохой путь +на открытых пространствах**. Если важна оптимальность - DFS не подходит. + +### 6.3. На взвешенном лабиринте с альтернативами - победа Dijkstra и A\* + +Лабиринт `weighted_choice` (21×13): открытая комната, в центре - болото 5×5 +(вес 3 за каждую клетку). Между стартом слева и выходом справа есть два +маршрута: +* «прямо через болото» - короче в клетках, но каждая болотная клетка стоит 3; +* «вокруг болота» - длиннее в клетках, но каждая стоит 1. + +Результаты: + +* BFS и DFS: путь **19 клеток**, **стоимость 29** (3 болотные × 3 = 9 «лишних» + единиц). +* A\* и Dijkstra: путь **25 клеток**, но **стоимость 25** - на 4 единицы + дешевле, потому что они учитывают вес клетки. + +Это и есть классическое преимущество взвешенных алгоритмов: +если шаги стоят по-разному (болото, песок, бездорожье), Dijkstra/A\* находят +оптимальный путь, а BFS/DFS - нет. + +### 6.4. На лабиринте без выхода + +`nopath_15x15`: все алгоритмы обходят все 165 проходимых клеток и возвращают +пустой путь. Время одинаковое - это, по сути, полный обход. Этот тест +показывает, что **все четыре стратегии корректно обрабатывают случай +отсутствия пути** (важная проверка). + +### 6.5. Время поиска ≠ качество пути + +Иерархия по скорости стабильна: **DFS < BFS < Dijkstra ≲ A\***. Но «быстрее» +не значит «лучше»: на `empty_30x30` DFS быстрее всех в 2 раза, но его путь +в 7 раз длиннее оптимального. На взвешенном лабиринте - BFS быстрее A\*, +но даёт более дорогой путь. + +**Вывод по алгоритмам:** + +| Когда подходит | Что выбрать | +| --- | --- | +| Минимум числа шагов на одинаковых клетках | **BFS** | +| Нужно быстро найти **хоть какой-то** путь | **DFS** | +| Взвешенный граф, есть хорошая эвристика | **A\*** (быстрее Dijkstra) | +| Взвешенный граф, эвристики нет | **Dijkstra** | + +## 7. Чем помогли паттерны + +Без паттернов код бы выглядел как один большой скрипт с `if maze_format == 'txt'` +и `if algorithm == 'bfs'`. Что я получил с паттернами: + +1. **Builder** - добавить новый формат лабиринта (JSON, графический PNG, генератор) + = новый класс, всё остальное не трогаем. +2. **Strategy** - добавить новый алгоритм (двунаправленный BFS, IDA\*) = новый + класс. `MazeSolver` не меняется. +3. **Observer** - `MazeSolver` ничего не знает про вывод. Я могу подключить + `ConsoleView` для интерактива и `CSVLogger` для эксперимента одновременно. + Эксперимент это и делает: подключает «тихого» наблюдателя. +4. **Command** - ручное прохождение и `undo` получаются естественно. + Расширить до `redo` - добавить второй стек. + +Что было бы сложно изменить без паттернов: + +* Сменить алгоритм поиска в рантайме без `if/elif`-простыни. +* Добавить второй вид визуализации (например, GUI) без затрагивания решателя. +* Поддержать сразу два формата лабиринта. + +## 8. Выводы + +* Реализованы четыре алгоритма поиска пути и четыре паттерна проектирования. +* Эксперимент подтвердил классические свойства алгоритмов: DFS быстрый, но + не оптимальный; BFS оптимален по шагам; A\*/Dijkstra оптимальны по + стоимости; A\* быстрее Dijkstra при наличии хорошей эвристики. +* Особенно выпукло разница видна на двух «диагностических» лабиринтах: + `empty_30x30` (DFS даёт «уродский» путь в 7 раз длиннее) и `weighted_choice` + (BFS/DFS режут через болото, Dijkstra/A\* обходят). +* Паттерны Builder/Strategy/Observer/Command превратили проект из «скрипта» + в расширяемое приложение. Новый формат, новый алгоритм или новый вид + визуализации добавляется без правки существующего кода + (принцип Open/Closed). diff --git a/SokolovEN/426 b/SokolovEN/426 new file mode 100644 index 00000000..e69de29b diff --git a/SokolovEN/docs/data/empty.txt b/SokolovEN/docs/data/empty.txt new file mode 100644 index 00000000..6d0a2495 --- /dev/null +++ b/SokolovEN/docs/data/empty.txt @@ -0,0 +1,49 @@ +######################################## +#S #

Влияние порядка данных на BST +При случайном порядке данных BST работает быстро (вставка ~0.005 сек). +При отсортированном порядке дерево вырождается в цепочку, и время вставки +возрастает примерно в 50–60 раз (~0.31 сек). Сложность деградирует с O(log n) до O(n). + +2. Почему хеш-таблица нечувствительна к порядку +Хеш-таблица использует хеш-функцию, которая равномерно распределяет элементы +по бакетам. Поэтому порядок входных данных почти не влияет на скорость +вставки, поиска и удаления (в среднем O(1)). + +3. Почему связный список медленен при поиске +Для поиска в связном списке нужно последовательно пройти все элементы. +Поэтому поиск всегда выполняется за O(n), независимо от порядка данных. +Это делает его самым медленным при операциях поиска и удаления. + +4.

Выводы + +Использование объектно-ориентированного подхода и паттернов проектирования существенно повысило гибкость и расширяемость кода. + +Преимущества: +- Благодаря паттерну **Strategy** добавление нового алгоритма поиска (например, Dijkstra) требует только реализации интерфейса `PathFindingStrategy` без изменения `MazeSolver`. +- Паттерн **Builder** позволяет легко подключать новые способы загрузки лабиринтов. +- Код стал более читаемым и поддерживаемым. + +Что было бы сложно изменить без паттернов: +- Замена алгоритма поиска потребовала бы значительных изменений в классе `MazeSolver` (много условных операторов `if`). +- Добавление нового способа построения лабиринта привело бы к дублированию кода. +- Сравнительный эксперимент было бы гораздо сложнее проводить, так как алгоритмы не были бы унифицированы через общий интерфейс. + +Таким образом, применение паттернов Strategy и Builder сделало систему легко расширяемой и удобной для проведения экспериментов. \ No newline at end of file diff --git a/SolovevDD/docs/data/2-nd_exersize/results/results.csv b/SolovevDD/docs/data/2-nd_exersize/results/results.csv new file mode 100644 index 00000000..8a35a147 --- /dev/null +++ b/SolovevDD/docs/data/2-nd_exersize/results/results.csv @@ -0,0 +1,16 @@ +лабиринт,стратегия,время_мс,посещено_клеток,длина_пути +10x10_simple,BFS,0.0646,82,1 +10x10_simple,DFS,0.0633,82,1 +10x10_simple,AStar,0.0929,82,1 +50x50_with_deadends,BFS,1.3632,1687,0 +50x50_with_deadends,DFS,0.1943,400,205 +50x50_with_deadends,AStar,0.6863,562,101 +100x100_complex,BFS,4.8617,6060,1 +100x100_complex,DFS,4.6471,6060,1 +100x100_complex,AStar,7.4691,6060,1 +empty,BFS,0.6954,900,0 +empty,DFS,0.4106,900,465 +empty,AStar,1.0604,900,59 +no_exit,BFS,0.0017,1,1 +no_exit,DFS,0.0009,1,1 +no_exit,AStar,0.001,1,1 diff --git a/SolovevDD/docs/data/2-nd_exersize/results/time_comparison.png b/SolovevDD/docs/data/2-nd_exersize/results/time_comparison.png new file mode 100644 index 00000000..9d2f13dd Binary files /dev/null and b/SolovevDD/docs/data/2-nd_exersize/results/time_comparison.png differ diff --git a/SolovevDD/docs/data/2-nd_exersize/results/visited_comparison.png b/SolovevDD/docs/data/2-nd_exersize/results/visited_comparison.png new file mode 100644 index 00000000..519d296c Binary files /dev/null and b/SolovevDD/docs/data/2-nd_exersize/results/visited_comparison.png differ diff --git a/SolovevDS/428b.md b/SolovevDS/428b.md new file mode 100644 index 00000000..e69de29b diff --git a/SolovevDS/docs/data/data_for_task1/data_structures.py b/SolovevDS/docs/data/data_for_task1/data_structures.py new file mode 100644 index 00000000..0f5879a4 --- /dev/null +++ b/SolovevDS/docs/data/data_for_task1/data_structures.py @@ -0,0 +1,203 @@ +#--------------------------------------Связный список-------------------------- +def ll_insert(head, name, phone): + # 1. если список пуст → новый элемент становится head + if head is None: + return {'name': name, 'phone': phone,'next': None} + + current = head + # 2. сначала проверим — может имя уже есть → тогда просто обновим + while current is not None: + if current['name'] == name: + current['phone'] = phone + return head + current = current['next'] + # 3. идём до конца списка + current = head + while current['next'] is not None: + current = current['next'] + # 4. добавляем новый узел в конец + current['next'] = {'name': name,'phone': phone,'next': None} + + return head + + +def ll_find(head, name): + current = head + + while current is not None: + if current['name'] == name: + return current['phone'] + + current = current['next'] + + return None + +def ll_delete(head, name): + current = head + previous = None + + while current is not None: + if current['name'] == name: + + # 1. удаляем голову списка + if previous is None: + return current['next'] + + # 2. удаляем середину или конец + previous['next'] = current['next'] + return head + + previous = current + current = current['next'] + + return head # если не нашли + +def ll_list_all(head): + result = [] + current = head + # 1. проходим по списку + while current is not None: + result.append((current['name'], current['phone'])) + current = current['next'] + # 2. сортируем по имени + result.sort(key=lambda x: x[0]) + + return result + + +#----------------------------------HASH-таблица-------------------------------- +def my_hash(s, M): + B = 31 + n = len(s) + h = 0 + for i in range(n): + h += ord(s[i]) * (B ** (n -

Особое внимание уделяется влиянию порядка входных данных (отсортированные vs случайные) на скорость операций вставки, поиска и удаления. + +## 2. Методика эксперимента + +* **Объем выборки:** $N = 10\,000$ записей (имя, телефон). +* **Режимы входных данных:** + * *Случайный (Shuffled)* — имена перемешаны. + * *Отсортированный (Sorted)* — имена идут по алфавиту. +* **Измеряемые метрики:** + * Время полной вставки $N$ элементов. + * Время 110 операций поиска (100 существующих + 10 несуществующих). + * Время 50 операций удаления. +* **Инструментарий:** Замеры выполнены через `time.perf_counter()`, анализ данных — через `pandas`, визуализация — через `matplotlib`. +* **Повторяемость:** Каждый тест запущен 5 раз для усреднения погрешности. + +## 3. Результаты +### 3.1.

Визуализация +![График производительности](data/plot.png) +*(На графике ось Y логарифмическая. Это необходимо, так как диапазон времен составляет от $10^{-4}$ до $30$ секунд).* + +## 4. Анализ результатов +### 4.1. Двоичное дерево поиска (BST) +Наблюдается критическая зависимость от порядка данных. +* **Случайные данные:** Дерево сбалансировано, операции выполняются быстро ($\approx O(\log N)$). Время вставки — 0.05 сек. +* **Отсортированные данные:** Произошла деградация до вырожденного дерева (по сути, связного списка). Каждая вставка проходит до самого глубокого уровня. Время вставки составило **~30 секунд**. +* **Вывод:** Простое BST не подходит для гарантированно упорядоченных данных. Для реальных систем требуется балансировка (AVL, Red-Black Trees). + +### 4.2. Хеш-таблица +Показала **стабильную производительность** вне зависимости от режима данных. +* Время вставки $\approx 0.01$ сек. +* Время поиска $\approx 0.0001$ сек (в 1000 раз быстрее поиска в списке). +* Это подтверждает теоретическую сложность $O(1)$ (в среднем). Хеш-функция равномерно распределила ключи, коллизий практически не было. + +### 4.3. Связный список +Демонстрирует самую низкую производительность среди структур для задач поиска. +* Вставка в случайном порядке занимает больше времени (10.8 сек), чем в отсортированном (6.8 сек), так как при случайном вставке элементы в среднем распределяются по списку равномернее, а при отсортированной вставке мы всегда идем до конца (хвост списка), что оптимизируется кешем процессора лучше, чем хаотичные переходы. +* Поиск занимает $\approx 0.1$ сек ($O(N)$), что значительно медленнее хеш-таблицы. + +## 5. Итоговые выводы + +1. **Для быстрого поиска и вставки (Телефонный справочник):** Идеально подходит **Хеш-таблица**. Она обеспечивает мгновенный доступ к данным ($O(1)$) и не чувствительна к порядку поступления информации. +2. **Для хранения данных в отсортированном виде:** Теоретически подходит **BST**, но только при условии, что данные поступают в случайном порядке. Если данные отсортированы заранее, производительность падает в 600 раз. В реальных проектах следует использовать самобалансирующиеся деревья. +3. **Связный список:** Неэффективен для задач типа "словарь" или "справочник" из-за линейной сложности поиска. Имеет смысл применять только там, где важна структура очереди или стека, либо в условиях жесткой экономии памяти. diff --git a/VasilevIA/lab1/Задание1.py b/VasilevIA/lab1/Задание1.py new file mode 100644 index 00000000..cf145fd9 --- /dev/null +++ b/VasilevIA/lab1/Задание1.py @@ -0,0 +1,252 @@ +import random +import pandas as pd +import time +import sys +import os +import matplotlib.pyplot as plt + +# Увеличиваем лимит рекурсии для BST на отсортированных данных (может достичь глубины N) +sys.setrecursionlimit(20000) + +# ========================================================= +# 1.

Анализ эффективности алгоритмов и применимости паттернов +### Алгоритмы + +**BFS** гарантирует кратчайший путь по числу шагов. Расширяет узлы слой за слоем во всех направлениях, поэтому посещает наибольшее число клеток. На практике это надёжный выбор когда нужен точно кратчайший маршрут. + +**DFS** посещает меньше клеток и выполняется быстрее - на large лабиринте в 1.8 раза быстрее BFS. Однако путь может быть далеко не кратчайшим. На пустом лабиринте DFS нашёл путь длиной 451 шаг, тогда как BFS и A* - 67. Это связано с тем, что DFS уходит в первое попавшееся направление и возвращается только в тупике. + +**A*** использует манхэттенскую эвристику h = |x1-x2| + |y1-y2| и должен в теории посещать меньше клеток чем BFS. На лабиринтах, сгенерированных алгоритмом recursive backtracker, выигрыш небольшой (примерно 5%). Причина: backtracker строит дерево - между любыми двумя клетками ровно один путь, тупиков нет, эвристика не помогает их обходить. На лабиринтах с циклами A* посещает заметно меньше клеток. Накладные расходы на работу с heap и closed-set делают A* медленнее по времени, чем DFS. + +На пустом лабиринте (без стен) A* ведёт себя как BFS. Математически: f(x,y) = g + h = (x-1+y-1) + (W-x+H-y) = const для всех клеток. Все узлы неразличимы по приоритету. + +На лабиринте без выхода все три алгоритма посещают одинаковое число клеток и корректно возвращают пустой путь. + +### Паттерны +**Builder** оказался полезным при добавлении нового типа лабиринта (взвешенного, с символами s и m). Изменения были внесены только в `TextFileMazeBuilder`, клиентский код не менялся. + +**Strategy** позволил в одном цикле запустить все три алгоритма через `solver.set_strategy(strategy)`. Без паттерна пришлось бы либо дублировать код запуска для каждого алгоритма, либо писать условные ветки. + +**Observer** полезен при расширении: чтобы добавить вывод в лог или консоль, достаточно написать новый Observer и подписать его на solver, не меняя `MazeSolver`. + +--- + +## 5. Выводы +ООП и паттерны позволили сделать код гибким в нескольких направлениях. + +Добавление нового алгоритма поиска сводится к написанию одного класса, реализующего `find_path()`. Без Strategy пришлось бы добавлять ветку в `solve()` и во все места, где запускается поиск. + +Добавление нового формата лабиринта - только новый класс Builder. Без паттерна логика парсинга была бы перемешана с логикой работы программы. + +Добавление нового способа отображения (GUI, запись в файл) - только новый Observer. Без него MazeSolver пришлось бы напрямую вызывать функции отображения, что создало бы зависимость от конкретной реализации. + +Без применения паттернов код решал бы задачу, но любое изменение требовало бы правки в нескольких местах сразу. С паттернами каждый класс отвечает за одну задачу и не знает о деталях реализации соседних классов. diff --git a/VasilevIA/lab2/main.py b/VasilevIA/lab2/main.py new file mode 100644 index 00000000..8a358bd2 --- /dev/null +++ b/VasilevIA/lab2/main.py @@ -0,0 +1,165 @@ +import csv +import os +import sys + +sys.path.insert(0, os.path.join(os.path.dirname(__file__), "codes")) + +from maze import TextFileMazeBuilder, MazeSolver, BFSStrategy, DFSStrategy, AStarStrategy +from maze_generator import generate_all + +try: + import matplotlib.pyplot as plt + import matplotlib + matplotlib.use("Agg") + HAS_PLT = True +except ImportError: + HAS_PLT = False + +BASE_DIR = os.path.dirname(__file__) +MAZES_DIR = os.path.join(BASE_DIR, "mazes") +RESULTS_DIR = os.path.join(BASE_DIR, "results") +RUNS = 7 + +MAZE_FILES = [ + ("small", "small.txt"), + ("medium", "medium.txt"), + ("large", "large.txt"), + ("empty", "empty.txt"), + ("no_exit", "no_exit.txt"), +] + + +def run(): + os.makedirs(RESULTS_DIR, exist_ok=True) + + if not os.path.exists(MAZES_DIR) or not os.listdir(MAZES_DIR): + generate_all(MAZES_DIR) + + strategies = [BFSStrategy(), DFSStrategy(), AStarStrategy()] + builder = TextFileMazeBuilder() + all_results = [] + + for label, filename in MAZE_FILES: + path = os.path.join(MAZES_DIR, filename) + if not os.path.exists(path): + continue + + maze = builder.build_from_file(path) + print(f"\nMaze: {label} ({maze.width}x{maze.height})") + + solver = MazeSolver(maze, strategies[0]) + + for strategy in strategies: + solver.set_strategy(strategy) + times, visited_list, lengths = [], [], [] + + for _ in range(RUNS): + stats = solver.solve() + times.append(stats.time_ms) + visited_list.append(stats.visited) + lengths.append(stats.path_length) + + avg_time = sum(times) / RUNS + avg_visited = sum(visited_list) / RUNS + avg_len = sum(lengths) / RUNS + + found = f"length={avg_len:.0f}" if avg_len > 0 else "not found" + print(f" {strategy.name:<6} time={avg_time:.4f} ms visited={avg_visited:.0f} {found}") + + all_results.append({ + "maze": label, + "strategy": strategy.name, + "time_ms": round(avg_time, 4), + "visited_cells": round(avg_visited, 1), + "path_length": round(avg_len, 1), + }) + + save_csv(all_results) + save_plots(all_results) + show_sample() + print("\nDone.

+Были использованы паттерны: + +- Builder — для загрузки лабиринта из файла. +- Strategy — для переключения алгоритмов поиска пути. +- Observer — для уведомлений о событиях поиска. + +Использование паттернов позволило сделать архитектуру гибкой и расширяемой. + +Например: +- можно легко добавить новый алгоритм поиска пути; +- можно реализовать другой способ загрузки лабиринта; +- можно подключить новые способы отображения информации. + +Без применения паттернов код был бы более связанным и сложным для расширения и поддержки. \ No newline at end of file diff --git

И сложность меняется с логарифмической O(log n) на линейную O(n). Вставка для неотсортированных данных заняла 0.016531 с, а для отсортированных: 7.112118 с, разница в 430 раз. Получается, что BST сильно зависит от входных данных. +### Почему хеш-таблица почти не чувствительна к порядку +Хеш-таблица имеет низкую чувствительность к порядку входных данных, поскольку хеш-функция вычисляет индекс в массиве на основе значения ключа, обеспечивая равномерное распределение элементов по бакетам независимо от их исходной последовательности. По графикам видно, что разница между случайными и отсортированными данными минимальна. И для всех операций сложность составляет O(1). +### Почему связный список всегда медленен при поиске +Связный список всегда медленен при поиске, потому что у него отсутствует прямой доступ к элементам, и нужно перебирать все элементы по порядку. И из-за этого связный список имееет сложность O(n). +### Как удаление работает в каждой структуре +- **Связный список:** Сначала программа ищет нужный элемент, перебирая их по порядку от головы, что занимает время O(n). Как только элемент найден, то у предыдущего обновляется ссылка на элемент, который шел после удаляемого, что занимает время O(1). По графикам видно, что время удаления близко ко времени поиска. Время удаления для отсортированных данных: 0.017500 с, а для случайных: 0.018947 с. +- **Хеш-таблица:** Программа определяет нужный бакет и удаляет элемент из короткого связного списка внутри этого бакета за O(1). Время удаления для отсортированных данных: 0.000036 с, а для случайных: 0.000043 с. +- **Двоичное дерево поиска:** Нет потомков: Узел просто стирается. Один потомок: Потомок занимает место удаленного родителя. Два потомка: На место удаленного узла ставится самый минимальный элемент из его правого поддерева. Для случайных данных занимает O(log n), а для отсортированных данных занимает O(n). Время удаления для отсортированных данных: 0.039463 с, а для случайных: 0.000153 с. + +# Вывод +На основе полученных результатов можно сделать вывод: +- **Связный список:** всегда имеет линейную сложность O(n), что делает его неподходящим для задач частых вставок, частого поиска и получения данных в порядке. Но подходит только в узких случаях: максимально быстрая вставка и удаление элементов в начало или конец структуры(очереди, стеки). +- **Хеш-таблица:** является лучшим выбором для максимально задач частого поиска, добавления и удаления элементов, которые имеют сложность O(1), при этом порядок входных данных не имеет значение. Она идеально подходит для словарей и кэшей. +- **Двоичное дерево поиска:** Необходимо использовать в тех случаях, когда необходимо получать данные в отсортированном состоянии и выполнять поиск в заданном диапазоне значений. При случайных входных данных имеет хорошую сложность O(log n), но при получении отсортированных входных данных сложность возрастает до линейной O(n). + +Таким образом, для реальных задач наиболее подходят хеш-таблицы или сбалансированные деревья, если требуется получить данные в отсортированном виде. \ No newline at end of file diff --git a/YanyaevAA/docs/data/graphics.png

В лабиринтах 50x50, 100x100 показывает неэффективность алгоритма с точки зрения объема работы: 799 и 3576 соответственно. + - Длина пути: Во всех алгоритмах показывает выбор оптимального пути. +- **DFS**: + - Время: В маленьком лабиринте (10x10) работает медленнее других, но на больших и пустом лабиринтах является быстрейшим алгоритмом. Это происходит, потому что DFS использует стек, который в Python имеет сложность O(1). + - Количество посещенных клеток: На полученных данных, мы видим хорошие значения посещенных клеток, но для такого же по размерам лабиринта, но с другими путями, количество посещенных клеток может измениться. Это происходит из-за того, что количество посещенных клеток зависит от лабиринта, и "повезло" ли алгоритму сразу же наткнуться на коридор, ведущий к выходу. + - Длина пути: На маленьком лабиринте (10x10) показывает одинаковую длину пути со всеми алгоритмами. Но для других лабиринтов показывает пути значительно больше чем у других. DFS не гарантирует оптимальность пути, потому что ищет до первого пути ведущего к выходу, который может быть большим. Но на лабиринте без развилок (10x10) показывает результат на ровне с другими алгоритмами. +- **A***: + - Время: На большинстве лабиринтах показывает средние результат, в лабиринте без выхода и в пустом лабиринте показывает худшие результаты. Это происходит, потому что алгоритм использует приоритетную очередь, которая имеет логарифмическую сложность O(log n), также постоянная перестройка очереди занимает чуть больше времени. + - Количество посещенных клеток: Во всех случаях имеет минимальное количество посещенных клеток. Это происходит благодаря эвристической функции (Манхэттенское расстояние). Она минимизирует количество посещенных клеток, избегая ложные направления. Преимущество алгоритма хорошо видно на больших лабиринтах (50x50, 100x100) + - Длина пути: Также, как и BFS, показывает минимальную длину пути. Алгоритм выбирает кратчайший путь, также благодаря эвристике. +## Выводы по алгоритмам +- **BFS**: Всегда находит кратчайший путь, но для больших лабиринтов тратит много времени, а также для поиска пути исследует большое количество клеток. +- **DFS**: Алгоритм подходит для быстрого нахождения пути для простых или линейных лабиринтов. Но не подходит для выбора кратчайшего пути. +- **A***: Алгоритм показывает наибольшую общую эффективность. Всегда находит кратчайший путь и для поиска посещает наименьшее количество клеток, имеет хорошую скорость выполнения. +## Применяемость паттернов +- **Builder**: Позволяет отделить структуру самого лабиринта от источника его данных. Позволяет свободно, при необходимости, добавлять другие форматы, из которых будет строиться лабиринт. +- **Strategy**: Инкапсулирует алгоритмы поиска пути в отдельные классы, что позволяет свободно добавлять другие алгоритмы поиска +- **Observer**: Реализует механизм уведомления о шагах алгоритма. Позволяет визуализировать процесс поиска клеток, полностью отделяя логику вычислений от графического интерфейса. +# Вывод +Применение принципов И паттернов ООП позволило создать устойчивую к изменениям программу. Можно свободно добавлять новые алгоритмы поиска или новые способы вывода данных, создавая новые подклассы и не меняя ни единой строчки кода. Без ООП стало бы невозможно легко переключиться с чтения текстовых файлов на файлы другого формата или на алгоритм случайной генерации карт. В итоге ООП позволяет расширять код, не затрагивая работоспособность других компонентов. \ No newline at end of file diff --git a/YanyaevAA/task2/docs/data/100x100.txt

Постановка задачи + +Цель — разработать программу для загрузки лабиринта из текстового файла, поиска маршрута от старта до выхода с возможностью выбора алгоритма, визуализации процесса и экспериментального сравнения эффективности трёх классических алгоритмов поиска пути. + +### Основные требования: +- Модель лабиринта: классы `Tile` (клетка) и `Labyrinth` (сетка). +- Загрузка карты из файла с символами `#` (стена), `S` (старт), `E` (выход). +- Реализация трёх стратегий поиска: BFS, DFS, A*. +- Оркестратор `LabyrinthSolver` с возможностью смены алгоритма во время выполнения. +- Сбор метрик: время работы (мс), количество посещённых клеток, длина найденного пути. +- Проведение экспериментов на пяти лабиринтах разного размера и структуры. + +### Использованные паттерны проектирования + +- **Builder** – `TextLabyrinthBuilder` инкапсулирует логику парсинга текстового файла и создания объекта `Labyrinth`. Это упрощает добавление новых форматов. +- **Strategy** – `BFS_Pathfinder`, `DFS_Pathfinder` и `AStar_Pathfinder` реализуют общий интерфейс `Pathfinder`. Класс `LabyrinthSolver` может динамически переключаться между ними. +- **Observer** – интерфейс `GameObserver` и его реализация `TerminalDisplay` позволяют отделить отображение лабиринта от бизнес-логики. +- **Command** – `MoveAction` оборачивает перемещение игрока, сохраняя историю и предоставляя возможность отмены (`undo`). + +## 2. Архитектура приложения + +- **Модель**: `Tile` (клетка) и `Labyrinth` (лабиринт). +- **Загрузка**: `LabyrinthBuilder` (абстрактный) и `TextLabyrinthBuilder`. +- **Алгоритмы**: `BFS_Pathfinder`, `DFS_Pathfinder`, `AStar_Pathfinder` — наследники `Pathfinder`. +- **Управление поиском**: `LabyrinthSolver` (смена стратегии, оповещение наблюдателей). +- **Визуализация**: `TerminalDisplay`, реализующий `GameObserver`. +- **Интерактив**: `Explorer` (игрок) и `MoveAction` (команда перемещения). + +## 3. Реализация алгоритмов поиска пути + +### BFS (поиск в ширину) +Использует очередь. Стартовая клетка помещается в очередь, затем на каждом шаге извлекается первый элемент. Если это выход — путь восстановлен. Иначе все непосещённые соседи добавляются в конец очереди. Гарантирует кратчайший путь по количеству шагов. + +### DFS (поиск в глубину) +Вместо очереди используется стек (LIFO). Начинает со старта, на каждом шаге извлекается последний добавленный элемент. Быстрее продвигается в глубину, но путь часто оказывается далеко не оптимальным. + +### A* (A-звездочка) +Применяет приоритетную очередь с эвристической функцией `f = g + h`, где `g` — реальная стоимость пути от старта, `h` — Манхэттенское расстояние до выхода. Всегда находит оптимальный путь при допустимой эвристике и обычно посещает меньше клеток. + +## 4.

В пустом 15×15 путь составил 109 шагов вместо оптимальных 25. +- Число посещённых клеток невелико, что объясняет высокую скорость. Рекомендуется, когда важнее скорость, а не качество маршрута. + +**A*** +- Находит кратчайший путь во всех случаях (где он существует). +- Посещает в среднем меньше клеток, чем BFS (22, 28, 60, 169), что подтверждает эффективность эвристики. +- Время работы немного выше, чем у BFS, из-за накладных расходов на работу с кучей, однако разница незначительна. + +### Особые случаи + +- В лабиринте **No exit** все алгоритмы быстро обошли доступную область (9 клеток) и корректно вернули пустой путь. +- На **Empty 15×15** DFS показал наихудший путь (109 шагов), в то время как BFS и A* дали идеальные 25. Это наглядно демонстрирует, что DFS непригоден для задач, требующих оптимальности. +- **Large 20×20** показал близкие результаты для BFS и A* по длине пути, но DFS снова выдал более длинный маршрут (41). + +### Выводы и рекомендации + +- Если необходим **кратчайший путь** — выбирайте **BFS** или **A***. A* часто эффективнее по памяти, так как посещает меньше клеток. +- Если важна **максимальная скорость** и допустим неоптимальный путь — используйте **DFS**. +- **A*** является наилучшим компромиссом для большинства практических задач благодаря сбалансированному сочетанию времени и оптимальности. + +## 6. Заключение + +Разработанное приложение демонстрирует применение паттернов проектирования для построения гибкой и расширяемой архитектуры. +Экспериментальные данные подтверждают ожидаемое поведение алгоритмов: BFS и A* гарантируют оптимальность, DFS — высокую скорость ценой качества маршрута. A* показал наилучшее соотношение «затраты / качество», посещая меньше клеток и находя кратчайший путь. + +Все полученные метрики сохранены в файл `experiment_data.csv`, графики — в

работа: Сравнение структур данных для телефонного справочника + +## 1. Введение + +В рамках работы были реализованы три структуры данных «с нуля» на языке Python без использования классов, в процедурной парадигме: + +- **Связный список** — узлы хранятся в виде словарей `{'name', 'phone', 'next'}`. +- **Хеш-таблица** — массив фиксированного размера (1000 корзин), в каждой из которых хранится связный список (отдельные цепочки). +- **Двоичное дерево поиска (BST)** — узлы имеют поля `left`, `right`. + +Для каждой структуры реализованы операции `insert`, `find`, `delete`, `list_all` (возвращает записи, отсортированные по имени). + +Цель эксперимента — измерить производительность операций на наборе из **10 000 записей** при двух режимах подачи данных: **случайный порядок** и **отсортированный по имени**. Каждый опыт повторялся 5 раз, результаты усреднены. Измерялось общее время: + +- вставки всех 10 000 записей; +- поиска 110 записей (100 существующих + 10 несуществующих); +- удаления 50 случайных записей. + +## 2. Результаты измерений + +В таблице приведены средние значения времени (в секундах) для каждой структуры и режима. + +| Структура | Режим | Вставка (с) | Поиск (с) | Удаление (с) | +|----------------|-------------|------------|-----------|--------------| +| **LinkedList** | случайный | 4.1342 | 0.0282 | 0.0138 | +| LinkedList | сортир. | 3.7426 | 0.0248 | 0.0116 | +| **HashTable** | случайный | 0.00940 | 0.000075 | 0.000037 | +| HashTable | сортир. | 0.00915 | 0.000070 | 0.000032 | +| **BST** | случайный | 0.02396 | 0.000216 | 0.000126 | +| BST | сортир. | 9.1117 | 0.0796 | 0.0512 | + +*Графическое представление результатов* приведено на рисунке `performance_comparison.png`, где для каждой операции построены столбчатые диаграммы с группировкой по структурам и режимам. + +## 3. Анализ результатов + +### 3.1. Влияние порядка данных на BST + +Двоичное дерево поиска чувствительно к порядку поступления ключей. При вставке в отсортированном порядке дерево вырождается в линейный список (все узлы уходят в правое поддерево). Высота становится O(n), что приводит к резкому падению производительности: + +- Вставка на отсортированных данных (9.11 с) **медленнее в 380 раз**, чем на случайных (0.024 с). +- Поиск замедляется в ~370 раз, удаление — в ~406 раз. + +Фактически BST на отсортированных данных работает хуже даже связного списка из‑за рекурсивных вызовов и накладных расходов. + +### 3.2. Устойчивость хеш-таблицы к порядку + +Хеш-функция равномерно распределяет имена по корзинам вне зависимости от порядка поступления. Поэтому времена вставки, поиска и удаления практически идентичны для случайного и отсортированного режимов: + +- Вставка: 0.00940 с (случ.) vs 0.00915 с (сорт.) — разница в пределах погрешности. +- Поиск и удаление также стабильны. + +Средняя сложность O(1) подтверждается на практике. + +### 3.3. Связный список — линейная сложность на всех операциях + +Связный список не обеспечивает прямого доступа к элементам. Для поиска, обновления или удаления требуется последовательный проход, что даёт O(n). + +- Вставка 10 000 элементов занимает около 4 секунд (даже больше, чем BST на случайных данных). +- Поиск (~0.028 с) на порядок медленнее, чем в хеш-таблице и BST на случайных данных. +- Порядок входных данных почти не влияет на производительность (разница менее 10%), так как в любом случае приходится обходить список до конца для вставки новых уникальных имён. + +### 3.4. Сравнение удаления + +- **Связный список**: удаление требует сначала найти элемент (O(n)), затем переставить ссылки. Время ~0.012–0.014 с, что близко ко времени поиска. +- **Хеш-таблица**: удаление за O(1) в среднем — достаточно вычислить хеш и удалить из короткого списка корзины. Время ~0.00003–0.00004 с. +- **BST**: на случайных данных удаление очень быстрое (0.000126 с) благодаря логарифмической высоте. На отсортированных данных время возрастает до 0.051 с (деградация до O(n)). + +## 4. Выводы и рекомендации + +На основе полученных результатов можно сделать следующие выводы о применимости структур в реальных задачах: + +- **Хеш-таблица** — лучший выбор, когда требуется максимальная скорость всех операций (вставка, поиск, удаление) и не важен порядок хранения. Она стабильна, не чувствительна к порядку входных данных и показывает среднее время O(1). Идеальна для реализации словарей, кэшей, индексов по ключу. + +- **Двоичное дерево поиска** — подходит, когда необходимо часто получать данные в отсортированном виде (например, вывод справочника по алфавиту) и гарантируется, что данные не будут поступать в отсортированном порядке (иначе дерево вырождается). В реальных проектах вместо простого BST следует использовать самобалансирующиеся деревья (AVL, красно-чёрные), которые сохраняют логарифмическую высоту при любых порядках. В эксперименте BST на случайных данных показал отличные результаты, близкие к хеш-таблице. + +- **Связный список** — из‑за линейной сложности основных операций непригоден для хранения больших объёмов данных (тысячи и более записей). Может применяться лишь для очень маленьких коллекций, при частых вставках в начало (здесь не рассматривалось) или в учебных целях. + +Таким образом, для телефонного справочника с 10 000 записей наиболее эффективной является **хеш-таблица**, обеспечивающая мгновенный доступ по имени. Если же требуется ещё и алфавитный вывод без дополнительной сортировки, стоит использовать **сбалансированное дерево поиска**. diff --git a/anikinvd/docs/report-2-nd.md b/anikinvd/docs/report-2-nd.md new file mode 100644 index 00000000..69d1b358 --- /dev/null +++ b/anikinvd/docs/report-2-nd.md @@ -0,0 +1,125 @@ +# Лабораторная работа: Поиск выхода из лабиринта + +## 1.

Он особенно эффективен, когда требуется минимальное разрастание поиска. +2. **DFS – самый быстрый**, если не важна длина пути (например, для проверки существования выхода). +3. **BFS** остаётся простым и предсказуемым, но уступает A* по числу посещений. +4. В лабиринте без выхода все алгоритмы корректно обходят всю достижимую область (36 клеток) и возвращают пустой путь. + +### Рекомендации по выбору алгоритма + +| Сценарий | Рекомендуемый алгоритм | +|----------|------------------------| +| Нужен **гарантированно кратчайший путь** и не важна скорость | BFS или A* (A* предпочтительнее) | +| **Скорость критична**, путь может быть неоптимальным | DFS | +| Нужен **компромисс** (оптимальность + мало посещений) | A* | +| Проверка **существования пути** (без восстановления маршрута) | DFS | + +## 6. Заключение + +Применение паттернов проектирования (Builder, Strategy, Observer, Command) позволило создать гибкую, расширяемую и легко тестируемую программу. Реализованные алгоритмы поиска пути были экспериментально сравнены на лабиринтах разной сложности. Полученные результаты подтверждают теоретические оценки: A* даёт наилучшее сочетание оптимальности и эффективности по числу посещённых клеток, DFS выигрывает по скорости, а BFS остаётся простым базовым решением. + +Программа также предоставляет интерактивный режим с ручным управлением игроком и возможностью отмены ходов. + diff --git a/chizhikovaSM/428.md b/chizhikovaSM/428.md new file mode

Было выполнено экспериментальное сравнение эффективности операций добавления, поиска и удаления на выборке из 10 000 записей. Для каждой структуры испытания проводились на двух типах входных данных — с произвольным порядком записей и с порядком, отсортированным по имени. Каждый эксперимент выполнялся пять раз, после чего результаты были усреднены. +2.

Анализ результатов +3.1. Как порядок данных влияет на бинарное дерево поиска (BST) +Если данные поступают в отсортированном порядке, BST теряет свои свойства и превращается в линейный список: каждый новый элемент добавляется только в правое поддерево. Высота дерева становится равной числу элементов, а трудоёмкость операций возрастает до O(n). Экспериментальные данные это подтверждают: При добавлении отсортированных записей время вставки в BST составило 3,77 с — это в 256 раз дольше, чем на случайных данных (0,01632 с). Более того, на отсортированных данных BST вставил элементы медленнее, чем связный список (2,9 с), что связано с дополнительными затратами на рекурсивные вызовы. Операции поиска и удаления также замедлились примерно в 80 раз по сравнению со случайным порядком. +3.2. Почему хеш-таблица не чувствительна к порядку +Хеш-таблица распределяет ключи по корзинам с помощью хеш-функции, которая работает одинаково хорошо независимо от порядка поступления данных. Поэтому производительность остаётся стабильной: В случайном и отсортированном режимах время вставки почти одинаково: 0,0198 с и 0,0196 с соответственно. Поиск — около 0,017 с в обоих случаях. Небольшие различия объясняются случайным возникновением коллизий. Это полностью соответствует ожидаемой средней сложности O(1). +2.3. Почему связный список медленно выполняет поиск + В связном списке нет прямого доступа к элементам — чтобы найти запись, нужно последовательно перебирать узлы, что даёт сложность O(n). Результаты эксперимента: Поиск в списке (≈0,027 с) заметно медленнее, чем в хеш-таблице (0,000215 с) и в BST на случайных данных (0,000153 с). С ростом объёма данных это отставание будет только увеличиваться. Вставка в список тоже выполняется довольно долго (2,8 с), поскольку требует перебора до конца списка — в тесте все имена уникальны, поэтому каждая вставка проходит весь список. +3.4. Сравнение скорости удаления +Связный список: сначала необходимо найти элемент (O(n)), затем переназначить указатели (O(1)). Время удаления (0,017 с) почти совпадает со временем поиска — это логично. Хеш-таблица: удаление происходит в среднем за O(1) — находится нужная корзина, а затем из короткого списка удаляется элемент. Время удаления (0,000105–0,000127 с) значительно ниже, чем в связном списке. BST: на случайных данных удаление очень быстрое (0,000091 с) благодаря логарифмической высоте дерева. Однако на отсортированных данных время вырастает до 0,015501 с (в 50 раз), что отражает деградацию структуры до O(n). + 4. Выводы и рекомендации по выбору структуры + Основываясь на полученных в ходе эксперимента данных, можно дать следующие практические рекомендации: Хеш-таблица — лучший вариант, если важна максимальная скорость операций добавления, поиска и удаления, а порядок хранения элементов не имеет значения. Она идеально подходит для реализации словарей, кэшей, индексных хранилищ по ключу. В проведённых тестах хеш-таблица продемонстрировала стабильно высокую производительность во всех сценариях. Бинарное дерево поиска стоит выбирать в тех случаях, когда требуется получать данные + + +в отсортированном виде (например, вывод записей телефонного справочника по алфавиту). При этом нужно иметь в виду серьёзный недостаток: если входные данные поступают уже упорядоченными, дерево вырождается в линейный список, и эффективность резко падает. В подобных ситуациях рекомендуется применять сбалансированные деревья (AVL или красно-чёрные). В эксперименте BST на случайных данных работало почти так же хорошо, как хеш-таблица, а на отсортированных — показало наихудшие результаты. Связный список малопригоден для работы с большими объёмами данных из-за линейной сложности основных операций. Его применение оправдано лишь для очень маленьких коллекций, в задачах с частыми вставками в начало списка (в данном тестировании этот случай не рассматривался) или в обучающих целях. +Итог: в реальных проектах выбор чаще всего сводится к хеш-таблицам или сбалансированным деревьям — в зависимости от того, насколько критична упорядоченность хранимых данных. \ No newline at end of file diff

Даже два последовательных имени в отсортированном списке (`User_00001` и `User_00002`) с высокой вероятностью попадут в разные корзины. + +2. **Отсутствие структурной зависимости:** В отличие от дерева, хеш-таблица не хранит связи между соседними элементами. Каждый элемент хранится независимо, и его положение определяется только хеш-значением. + +3. **Случайное распределение:** Хеш-функция обеспечивает псевдослучайное распределение ключей по корзинам, что делает порядок вставки нерелевантным. + +Небольшое ускорение на отсортированных данных может объясняться кэшированием процессора при последовательном доступе к памяти. + +--- + +### 6.3 Почему связный список всегда медленен при поиске + +| Операция | Время (среднее) | Сложность | +|----------|----------------|-----------| +| Вставка | ~0.125 сек | O(n) | +| Поиск | ~0.0095 сек | O(n) | +| Удаление | ~0.001 сек | O(n) | + +**Анализ:** + +Связный список всегда медленен при поиске по следующим причинам: + +1. **Отсутствие индексов:** Нет быстрого способа найти элемент, кроме последовательного перебора всех узлов с начала. + +2. **Последовательный доступ:** Нельзя перейти к середине списка, как в массиве (отсутствует произвольный доступ по индексу). + +3. **Лучший случай (O(1)):** Достигается только если искомый элемент находится в начале списка. + +4. **Худший случай (O(n)):** Если элемент в конце или отсутствует, нужно обойти весь список из n элементов. + +5. **Отсортированность не помогает:** Даже если список отсортирован по имени, поиск остаётся линейным, так как у узлов нет указателей на середину (в отличие от массива, где можно использовать бинарный поиск). + +--- + +### 6.4 Как удаление работает в каждой структуре + +| Структура | Время (случайный порядок) | Механизм удаления | Сложность | +|-----------|--------------------------|-------------------|-----------| +| Связный список | 0.000623 сек | Поиск узла + переназначение указателя предыдущего узла на следующий | O(n) | +| Хеш-таблица | 0.000226 сек | Хеширование имени → поиск в цепочке → удаление из связного списка в корзине | O(1) среднее | +| Двоичное дерево | 0.000059 сек | Поиск узла + замена на inorder-преемника | O(log n) среднее | + +**Подробное описание алгоритмов:** + +**Связный список:** +1.

Постановка задачи + +Целью работы является создание программы для нахождения маршрута в лабиринте от начальной точки до выхода.

Сравнительный анализ +2.1. Влияние порядка данных на BST: деградация до O(n) +На shuffled-данных дерево строится относительно сбалансированным, и операции выполняются в среднем за O(log N). +На sorted-данных каждая следующая вставка попадает строго в правого потомка, и дерево вырождается в линейный список. Глубина рекурсии достигает N = 10 000, что приводит к: + +колоссальному росту времени вставки (с ~0.055 сек до ~24 сек); + +значительному замедлению поиска и удаления (с ~0.0005 сек до ~0.21 сек и с ~0.00027 сек до ~0.13 сек соответственно). +Причина — рекурсивные функции вынуждены обходить все N узлов, превращая логарифмическую сложность в линейную. Практический вывод: использовать несбалансированное BST можно только при гарантированно случайном порядке поступающих ключей, иначе необходимы самобалансирующиеся варианты (AVL, красно-чёрное дерево). + +2.2. Почему хеш-таблица почти не чувствительна к порядку +Хеш-функция равномерно распределяет ключи по корзинам независимо от порядка поступления. Операции вставки, поиска и удаления сводятся к вычислению хеша и проходу по очень короткой цепочке (в среднем O(1)). Время вставки в отсортированном наборе даже чуть меньше (0.006 сек против 0.008 сек), что объясняется меньшим количеством коллизий при последовательном поступлении близких имён (хотя разница несущественна). Поиск и удаление занимают доли миллисекунды и практически не зависят от размера набора в исследованном диапазоне. Хеш-таблица демонстрирует наилучшую устойчивость к любым шаблонам входных данных при условии хорошей хеш-функции и адекватного размера. + +2.3. Почему связный список всегда медленен при поиске +В односвязном списке единственный способ найти элемент — линейный проход от головы к хвосту. Среднее время поиска — O(N), то есть пропорционально количеству записей. В эксперименте при 10 000 записей и поиске 110 имён время составило около 0.1 сек, что на три порядка хуже, чем у хеш-таблицы, и на два порядка хуже, чем у сбалансированного BST. Режим sorted/shuffled влияет слабо (для списка порядок вставки не меняет структуру). Медленный поиск — фундаментальное ограничение связного списка. + +2.4. Удаление в каждой структуре +Связный список: удаление требует поиска элемента (O(N)) и изменения ссылки у предыдущего узла. Время удаления соизмеримо с поиском (0.038–0.056 сек). + +Хеш-таблица: удаление выполняется за O(1) в среднем — вычисление индекса, поиск в цепочке (очень короткой) и изменение ссылок. Время минимально (~0.00004 сек). + +BST: удаление узла с двумя потомками требует поиска минимального элемента в правом поддереве. На сбалансированных данных (shuffled) время ~0.00027 сек. На вырожденных (sorted) удаление замедляется до 0.13 сек из-за необходимости обходить длинные цепочки. + +3. Выводы и практические рекомендации +Если преобладают частые поиск и вставка, а порядок данных не важен – оптимальный выбор хеш-таблица. Она обеспечивает константное среднее время операций и нечувствительна к порядку поступления ключей. Идеально для телефонного справочника, кешей, словарей. + +Если требуется хранить данные в отсортированном виде и нужны операции типа «найти следующий/предыдущий» – подходит BST, но обязательно самобалансирующееся (например, АВЛ или красно-чёрное дерево). Несбалансированное BST применимо только при случайном порядке вставки; иначе деградация до O(n) делает его бесполезным. + +Связный список стоит использовать лишь в случаях, когда операции поиска редки, а основные действия — добавление/удаление в начале или в середине списка при известной позиции. Для телефонного справочника он практически непригоден из-за линейного времени поиска. + +Таким образом, для типового приложения с преимущественно операциями поиска и вставки (например, адресная книга в мобильном телефоне) лучшим решением является хеш-таблица. Если же функциональность требует получения отсортированного списка контактов или диапазонных запросов, разумно применять сбалансированное дерево поиска. \ No newline at end of file diff --git a/kornevma/docs/report2.md b/kornevma/docs/report2.md new file mode 100644 index 00000000..3d50634b --- /dev/null +++ b/kornevma/docs/report2.md @@ -0,0 +1,125 @@ +1.

Анализ результатов +1. Время выполнения + +На маленьком лабиринте все алгоритмы работают доли миллисекунды, разница несущественна. + +На больших лабиринтах (large_empty и large_random) лидирует A* (10.63 мс на случайном), так как эвристика направляет поиск к цели, посещая меньше клеток. DFS показал 18.39 мс, BFS – 20.69 мс. + +На пустом лабиринте без стен A* и BFS посещают все клетки (10000), но BFS работает быстрее (28.16 мс), вероятно, из-за накладных расходов на приоритетную очередь в A*. DFS закончил раньше, но нашёл очень длинный извилистый путь (4951 шаг вместо минимальных 199). + +При отсутствии пути все алгоритмы вынуждены обойти всю доступную область (397 клеток), время почти одинаково (1.0–1.7 мс). + +2. Количество посещённых клеток + +BFS всегда посещает все клетки, достижимые до уровня выхода, поэтому при наличии пути в большом лабиринте число посещённых равно размеру компоненты связности (7396). + +DFS ведёт себя непредсказуемо: на пустом лабиринте он «закопался» в глубину и посетил лишь 5149 клеток, но путь получился крайне длинным. На случайном лабиринте также посещено меньше (6029), но путь всё равно неоптимален (615 против 201). + +A* использует эвристику, поэтому посещает значительно меньше клеток (2215 на большом случайном) и находит кратчайший путь (как BFS). + +3. Длина пути + +BFS всегда находит кратчайший путь (31, 199, 201). + +DFS в силу природы стека может сильно отклоняться, длина пути достигает 4951 на пустом лабиринте и 615 на случайном, что в десятки раз хуже оптимального. + +A* также находит кратчайший путь благодаря допустимой эвристике (манхэттенское расстояние не переоценивает стоимость). Длина совпадает с BFS. + +4. Взвешенные клетки (доп. задание) +Код поддерживает вес клетки (поле weight). Если в файле лабиринта указаны цифры (1,2,3), алгоритм A* учитывает их как стоимость перехода. Для сравнения можно реализовать алгоритм Дейкстры (он же A* с нулевой эвристикой). На однородных весах (1) Дейкстра эквивалентен BFS, на неоднородных – находит оптимальный путь, но посещает больше клеток, чем A*. В данной работе взвешенные лабиринты не замерялись, но архитектура Strategy позволяет легко добавить DijkstraPathFinding и провести аналогичные эксперименты. + +7. Выводы +По алгоритмам: + +BFS гарантирует кратчайший путь, но может исследовать много клеток. Подходит для небольших лабиринтов или когда критична оптимальность. + +DFS часто быстрее находит хоть какой-то путь, но он редко бывает коротким. Полезен, если важен факт достижимости, а не длина. + +A* с манхэттенской эвристикой сочетает оптимальность BFS и целенаправленность, посещая меньше клеток. Это лучший выбор для большинства практических задач поиска пути. + +По паттернам и архитектуре: + +Применение паттернов (Builder, Strategy, Observer, Command) обеспечило гибкость и расширяемость. Замена формата лабиринта, добавление нового алгоритма, изменение способа отображения или внедрение отмены действий не затрагивают ядро программы. + +Без паттернов пришлось бы менять множество классов при каждом новом требовании. Strategy позволила в одном цикле экспериментов легко переключать алгоритмы; Builder скрыл детали создания лабиринта; Observer отделил визуализацию; Command дал основу для интерактивного управления с историей. + +Полученный код может служить каркасом для более сложных проектов (игровой AI, маршрутизация, робототехника). + +Итог: Разработанная программа демонстрирует преимущества объектно-ориентированного подхода с паттернами при решении задачи поиска пути в лабиринте, а экспериментальные данные подтверждают теоретические ожидания относительно эффективности алгоритмов. \ No

Причина: при последовательной вставке отсортированных ключей каждый новый узел уходит в +правое поддерево предыдущего.

На отсортированных данных LinkedList не меняет поведение, тогда как BST деградирует +до 12.77 с - в этом единственном сценарии LinkedList оказывается быстрее BST. + +### Удаление + +LinkedList - чтобы удалить узел, нужно пройти список от головы до нужного элемента и перешить next предшественника. +Это O(N) в любом случае, порядок данных не имеет значения. Shuffled: 0.027 с, sorted: 0.026 с - разница в пределах погрешности. + +HashTable - вычисляем индекс бакета через `hash(name)`, затем удаляем узел из связного списка этого бакета. Порядок вставки не +влияет на то, в каком бакете лежит запись, поэтому время стабильно в обоих режимах: 0.00033 с. + +BST - ищем узел спуском по дереву, затем обрабатываем три случая: нет потомков, один потомок, два потомка. На случайных данных +дерево сбалансировано, глубина ~log N, удаление занимает 0.00014 с. На отсортированных данных дерево вырождено в +цепочку - каждый узел уходил в правое поддерево при вставке, поэтому поиск удаляемого узла проходит через всю цепочку O(N). +Результат: 0.061 с, то есть в ~435 раз медленнее. + +--- + +## Вывод + +**Частые вставки** - HashTable. Время вставки не зависит от порядка и объёма данных: индекс бакета вычисляется за O(1), +вставка в бакет - тоже O(1). Подтверждают цифры: 0.033 с на shuffled и 0.032 с на sorted при N=10000. + +**Частый поиск** - HashTable. По той же причине: `hash(name)` сразу указывает на нужный бакет, линейный перебор не нужен. +Find: 0.00057 с на shuffled, 0.00070 с на sorted - стабильно при любом входе. + +**Получить данные в отсортированном порядке** - BST при случайном порядке вставки. Элементы размещаются по правилу BST +(слева меньшие корня, справа большие корня), поэтому обход по схеме левое поддерево -> корень -> правое поддерево возвращает +все записи в алфавитном порядке без дополнительной сортировки. Важное условие: данные должны вставляться в случайном +порядке, иначе дерево вырождается (см. деградацию BST на отсортированных данных). + +LinkedList сам по себе проигрывает по всем операциям из-за O(N\*\*2) на вставку и O(N) на поиск. Однако его идея лежит в основе +хеш-таблицы: каждый бакет - это связный список, через который разрешаются коллизии. Как самостоятельная структура данных для +справочника он неэффективен, но как строительный блок внутри HashTable - незаменим. diff --git a/lomakinae/docs/02_report.md b/lomakinae/docs/02_report.md new file mode 100644 index 00000000..1a252a18 --- /dev/null +++ b/lomakinae/docs/02_report.md @@ -0,0 +1,349 @@ +# Отчёт.

Так как основные лабиринты (10x10, 50x50, 100x100) имеют только +один верный путь, итоговая длина маршрута у всех алгоритмов совпадает. Сравниваем время работы и количество +проверенных клеток. + +**1. Маленький лабиринт (10x10)** +Все алгоритмы отработали быстрее 0.05 мс. Алгоритм A\* оказался наиболее точным, так как посетил всего 18 клеток. +BFS проверил 33 клетки, а DFS проверил 32 клетки. + +**2. Средний лабиринт (50x50)** +Здесь BFS обошел больше всего пространства (1046 клеток) и работал дольше всех (1.31 мс). В данном тесте DFS удачно +выбрал направление и проверил меньше клеток (231 клетка за 0.25 мс). Алгоритм A\* показал стабильный результат, +посетив 414 клеток за 1.05 мс. + +**3. Большой лабиринт (100x100)** +На большой карте заметно преимущество A\*. Он нашел выход за 0.98 мс, посетив всего 380 клеток. BFS пришлось проверить +почти весь лабиринт (2319 клеток), на что ушло 3.15 мс. DFS справился за 0.77 мс и проверил 662 клетки. + +**4. Пустой лабиринт (без стен)** +В пустом пространстве все алгоритмы посетили одинаковое количество клеток (90 шт.). Однако DFS повел себя неоптимально +и построил длинный зигзагообразный маршрут в 54 шага. BFS и A\* нашли прямой и кратчайший путь всего за 18 шагов. + +**5. Лабиринт без выхода** +Все алгоритмы корректно обработали тупик и завершили работу без ошибок. Так как выхода нет, им пришлось проверить +абсолютно все доступные клетки лабиринта (по 16 клеток у каждого). Длина пути у всех составила 0. Дольше всех из-за +расчета эвристики работал A\* (0.036 мс), а BFS и DFS справились за 0.02 мс. + +### Графики + +![plot](data/02/benchmark_charts.png) + +--- + +## 4. Анализ эффективности алгоритмов и применимость паттернов + +### Масштабирование по размеру лабиринта + +1. **A\*** - самый эффективный на больших картах. Благодаря Манхэттенской эвристике он учитывает направление + к выходу и минимизирует лишние шаги. На лабиринте 100х100 он проверил всего 380 клеток (против 2319 у BFS). + Минус - тратит чуть больше времени на мелких картах из-за математических расчетов. + +2. **BFS (Поиск в ширину)** - выполняет избыточное исследование графа во все стороны. Из-за этого на карте 100х100 + он посетил 2319 клеток, что увеличило время выполнения до 3.15 мс (худший результат по скорости). + +3. **DFS (Поиск в глубину)** - работает на простом стеке, поэтому у него минимальные накладные + расходы по времени (всего 0.77 мс на большой карте). Однако он не ищет оптимальный путь: на пустом лабиринте + `maze_empty` вместо прямой линии в 18 шагов он построил ломаный зигзаг в 54 шага. + +4. **Обработка тупиков (`maze_no_exit`)** - все алгоритмы успешно прошли стресс-тест. При отсутствии выхода они просто + обходят 100% доступных клеток и корректно возвращают пустой путь. + +### Применимость паттернов + +Паттерн **Strategy** позволил реализовать систему бенчмарков итерацией по массиву стратегий: `solver.set_strategy(strat)`. +Без него пришлось бы использовать `if-elif` внутри решателя, что нарушило бы принцип открытости-закрытости (OCP). Добавление +нового алгоритма (например, Дейкстры) не требует изменений в существующем коде. + +Паттерн **Builder** полностью инкапсулировал работу с файловой системой. Переход на другой формат хранения (JSON, бинарный) +требует только создания нового наследника `MazeBuilder` без изменения остальной системы. + +Паттерн **Facade** скрыл последовательность вызовов `run_benchmarks()` и `generate_plots()` за единственным методом +`run_full_diagnostic()`. Код `main.py` сведен к двум строкам и не зависит от деталей оркестрации подсистем. + +--- + +## 5. Выводы + +Для реальных задач: + +- Экспериментально подтверждено, что поиск ($A^*$) с использованием Манхэттенской + эвристики превосходит слепые методы (BFS, DFS) на больших лабиринтах. + +- Поиск в глубину непригоден для пустых пространств (строит крайне неоптимальные зигзагообразные пути) + и сильно зависит от порядка обхода соседей, но не требует хранения большого объёма данных в памяти. + +- Тестирование на изолированном лабиринте ("без выхода") доказало отказоустойчивость реализованных стратегий - алгоритмы + корректно завершают работу после полного исчерпания пространства состояний. + +Применение паттернов GoF (Builder, Strategy, Facade) обеспечило модульность и расширяемость системы. Добавление нового алгоритма, +формата файлов или этапа диагностики не затрагивает существующий код, что соответствует принципам SOLID. diff --git a/lomakinae/docs/data/01/README.md

Каждое выполнение функций проводилось с списоком из кортежей вида (владелецб номер), в котором было 1000 уникальных имен и еще 9000 имен, которые уже были использованны (всего 10000 кортежей). Каждое тестирование структур выполнялось для сортированного и не сортированного начального списка 10 раз. +## 2.

Анализ полученных данных +### 3.1 Зависимость скорости работы BST от порядка ввода данных. +Из полученных данных можно заметить, что для BST порядок ввода сильно сказывается на результате скорости выполнения программы: при послутплении неотсортированных данных программа справляется примерно в 3 раза быстрее. Связано это с тем, что каждое новое значение, при сортированных данных, будет больше предыдущего, а соответственно будет каждый раз создаватся правый лист, из-за чего высота дерева становится равной количесвту всех уникальных имен, вседствии чего сложность возрастает до О(n), а двоичное дерево превращается в своебразный связный список. + +### 3.2 Независимость скорости выполнения заполнения хеш-таблицы от порядка вводных данных +Из эксперемента можно заметить, что скорость заполнения хеш-таблицы сортированными и несортированными данными почти одинакова(разница менее 2%). Это объясняется наличием бакетов, которые разбивают все данные на N списков (В данной лабораторной работе N = 100) и не зависмо от способа подачи данных мы всегда получим N списков с одинаков наполнением. +Скорость выполнения вставки почти одинакова, так как и для случая сортированного и несортированного начального списка необходимо только определить нужный бакет и добавить в этот бакет кортеж (владелец, номер), то есть сложность операции О(1), что отражают результаты эксперемента. +Скорость выполнения поиска/удаления/составление списка почти одинаковы по тем же причинам: из-за наличия бакетов отрезаем часть лишних данных и уже работаем с оставшимеся, что значительно уменьшает время, а так как длина списока в бакете будет гораздо меньше длины списка исходных данных, что линейная сложность при переборе этого списка не сильно повлияет на время выполнения программы. + +### 3.3 Медленность посика связного списка +Чтобы найти нужный элемент в связном списке необходимо перебрать все элементы стоящие до него, и если элемент находится где-то в конце такого списка, то придется перебрать почти все значения, на что уйдет явно больше премени чем при применениеи хеш-таблицы, которая отсекает большую часть ненужных данных, или двоичного дерева, которое составлено так, что не нужно будет перебирать все значения. + +### 3.4 Принципы работы Удаления +### - Связный список: +В связном списке необходимо найти нужный словарь, значение ключа next содержит искомое имя. После этого мы меняем значение ключа next этого словаря на то, которое стоит в значении ключа next словаря, который мы собираемся удалить. Если мы хотим удалить запись, которой не существует, в таком случае перебираем весь связный спискок полностью и в случае ненахождения нужной записи возвращаем исходный список. + +### - Хеш-таблица: +В начале ищем номер нужного бакета, и начинаем искать в бакете необходую запись: перебираем список кортежей, пока не найдем нужную запись. Если запись нашлась, то удалем ее и списка, если нет, то возвращаем исходные данные без изменений + +### - Двоичное дерево посика: +Сначала ищем узел, который необходимо удалить, а затем действуем в зависимости от ситуации: +- 1 У узла нет потомков: + В такой ситуации просто удаляем наш узел(в данном случае лист) +- 2 У узла нет потомков справа или слева: + Если у узла есть только правые потомки, то на место этого узела помещаем узел, который расположен справа. Аналогично для случая с наличием левых потомков. +- 3 Если у узла есть и правые и левые потомки: + Находим самый маленький узел в правом поддереве этого узла, то есть идем сначала вправо от узла, а потом только влево, пока не дойдем до значения None. + Копируем значения этого наименьшего и подставляем эти данные в узел, который хотим удалить, не меняя значения под ключами left и right, а затем удаляем этот наименьший как описано в пунктах (1) и (2), так как этот узел или будет иметь только потомков вправа или не иметь их вообще + +## Вывод: в ходе выполнения лабораторной были изучены 3 способа хранения и обработки данных. Из данных полученных из эксперементов можно выделить наилучшие способы применения этих структур. Если в программе необходимо часто пополнять данные, корректировать, искать и удалять их, то лучше всего подойдет хеш-таблица. Если необходимо часто собирать все данные в один сортированный список и исходные данные несортированные, то хеш-таблица будет тормозить, в этом случае лучше использовать двоичное дерего поиска, хоть они и показывают более худший результат в добавлении, посике и удалении(примерно в 2.5-3 раза), но формируют список они моментально: 0.283 мс. Если же исходные данные отсортированны и необходимо выполнять все те же операции но без удаления, то в таком случае наиболее эффективным будет связный список. \ No newline at end of file diff --git a/lukovnikovde/docs/report_lab_2.md b/lukovnikovde/docs/report_lab_2.md new file mode 100644 index 00000000..81c3741e --- /dev/null +++ b/lukovnikovde/docs/report_lab_2.md @@ -0,0 +1,79 @@ +# Отчёт по лабораторной работе: Поиск пути в лабиринте + +## 1.

Легко добавить новый формат (JSON, бинарный) через новую реализацию `MazeBuilder`. | +| **Strategy** | `BFSStrategy`, `DFSStrategy`, `AStarStrategy` | Алгоритмы поиска пути можно менять на лету через `setStrategy()`. Новый алгоритм добавляется без изменения остального кода. | +| **Observer** | `ConsoleView` (подписан на события `MazeSolver`) | Отделяет отрисовку лабиринта и пути от логики поиска. Удобно заменить консольный вывод на GUI. | +| **Command** | `MoveCommand` | Позволяет пошаговое движение игрока по найденному пути, отмену ходов, макрокоманды. | + +--- + +## 3. Реализация алгоритмов поиска + +### 3.1 BFS (поиск в ширину) +- Использует очередь (`deque`). +- Гарантирует нахождение **кратчайшего пути** по количеству шагов. +- Сложность O(V + E), где V — количество клеток, E — рёбра. + +### 3.2 DFS (поиск в глубину) +- Использует стек (рекурсия или `list`). +- Быстрый, но **не гарантирует кратчайший путь**. +- Может «закопаться» вглубь, прежде чем найдет выход. + +### 3.3 A* (звездочка) +- Использует приоритетную очередь (`heapq`). +- Эвристика: **манхэттенское расстояние** до выхода. +- Компромисс между скоростью и оптимальностью: почти всегда находит кратчайший путь, но быстрее BFS на больших лабиринтах. + +--- + +## 4. Условия эксперимента + +| Параметр | Значение | +|----------|----------| +| Количество лабиринтов | 4 | +| Стратегии | BFS, DFS, A* | +| Количество запусков на каждом лабиринте | 5 | +| Типы лабиринтов | `small` (5×5), `medium` (15×15), `empty` (20×20), `no_exit` (10×10) | +| Инструмент замера времени | `time.perf_counter()` | +| Метрики | Время (мс), длина пути (клеток) | + +--- + +## 5.

Анализ результатов + +### 6.1 BFS +- **Плюсы:** всегда находит кратчайший путь. +- **Минусы:** медленнее DFS на больших лабиринтах из-за необходимости обходить все клетки по слоям. +- **Вывод:** лучший выбор, когда важна оптимальность пути. + +### 6.2 DFS +- **Плюсы:** самый быстрый, потребляет мало памяти. +- **Минусы:** может найти очень длинный неоптимальный путь (например, в `empty` путь в 67 клеток вместо 39). +- **Вывод:** подходит для задач, где путь может быть любым, а скорость важнее. + +### 6.3 A* +- **Плюсы:** почти идеальный компромисс: путь почти всегда кратчайший, скорость высокая. +- **Минусы:** требуется хорошая эвристика (у нас — манхэттенское расстояние). +- **Вывод:** рекомендуется для большинства практических задач поиска пути. + +### 6.4 Лабиринт без выхода +- Все алгоритмы перебирают весь лабиринт (или его часть) и возвращают пустой путь. +- BFS и A* делают это системно, DFS может уйти вглубь и долго возвращаться. + +--- + +## 7. Выводы + +### 7.1 О реализации +- **Паттерны** действительно сделали код гибким и расширяемым. +- **Builder** изолировал загрузку — легко поменять формат файла. +- **Strategy** позволил сравнивать алгоритмы без изменения `MazeSolver`. +- **Observer** и **Command** добавили визуализацию и управление, не засоряя основную логику. + +### 7.2 Рекомендации по выбору алгоритма + +| Сценарий | Рекомендуемый алгоритм | Почему | +|----------|------------------------|--------| +| Нужен кратчайший путь | BFS или A* | Оба находят оптимум, A* быстрее | +| Скорость важнее оптимальности | DFS | Самый быстрый | +| Лабиринт с известной эвристикой | A* | Лучший баланс | +| Лабиринт без выхода | BFS или A* | Предсказуемое перебор всех клеток | + +### 7.3 Заключение + +Лабораторная работа выполнена в полном объёме: +- ✅ Реализованы 4 паттерна проектирования. +- ✅ Программа загружает лабиринт из текстового файла. +- ✅ Реализованы 3 алгоритма поиска пути. +- ✅ Добавлена визуализация в консоли. +- ✅ Проведены эксперименты, результаты сохранены в CSV. +- ✅ Построены графики. +- ✅ Оформлен отчёт. + +Программа готова к использованию и легко расширяется. \ No newline at end of file diff

Архитектура системы + +Система состоит из следующих основных компонентов: + +Cell — описание клетки лабиринта; +Maze — структура лабиринта и логика соседей; +MazeBuilder — загрузка лабиринта из файла; +PathFindingStrategy — интерфейс алгоритмов поиска; +реализации стратегий: BFS, DFS, A*; +MazeSolver — оркестратор поиска и сбор статистики; +SearchStats — структура результатов; +ConsoleView — визуализация результата; +Command (опционально) — управление действиями пользователя. +5. Описание ключевых компонентов +Cell + +Хранит координаты клетки и её тип (стена, старт, выход). Определяет проходимость клетки. + +Maze + +Представляет лабиринт в виде двумерного массива клеток и предоставляет методы доступа к соседним узлам. + +TextFileMazeBuilder + +Отвечает за чтение текстового файла и построение объекта Maze. + +BFS / DFS / A* + +Реализуют разные стратегии поиска пути: + +BFS — гарантирует кратчайший путь; +DFS — быстрый, но не оптимальный; +A* — использует эвристику и уменьшает число посещённых клеток. +MazeSolver + +Запускает выбранный алгоритм, измеряет время выполнения и формирует статистику. + +SearchStats + +Содержит: + +время выполнения; +количество посещённых клеток; +длину найденного пути. +ConsoleView + +Отвечает за отображение лабиринта и найденного пути в консоли. + +6. Экспериментальная часть +6.1 Тестовые данные + +Для анализа использовались следующие типы лабиринтов: + +небольшой 10×10 с простым маршрутом; +средний 50×50 с наличием тупиков; +большой 100×100 со сложной структурой; +пустой лабиринт без стен; +лабиринт без решения. +6.2 Методика измерений + +Для каждой комбинации лабиринта и алгоритма выполнялось несколько запусков. + +Фиксировались следующие показатели: + +время выполнения (мс); +количество посещённых клеток; +длина пути. + +Результаты сохранялись в CSV-файл для последующего анализа. + +7. Анализ результатов +BFS + +Обеспечивает нахождение кратчайшего пути при равных весах переходов. Однако может исследовать значительное количество клеток. + +DFS + +Быстро находит решение в некоторых случаях, но не гарантирует оптимальность пути и может исследовать нерелевантные области. + +A* + +Использует эвристику (Манхэттенское расстояние), что позволяет существенно сократить количество посещённых узлов и ускорить поиск. + +Лабиринт без решения + +Во всех алгоритмах происходит полный или частичный обход доступной области, после чего возвращается отсутствие пути. + +Вывод по алгоритмам +BFS — оптимален по длине пути; +DFS — прост, но нестабилен; +A* — наиболее эффективен по числу посещений и времени работы. +8. Роль ООП и паттернов + +Использование ООП и паттернов проектирования позволило: + +разделить систему на независимые компоненты; +упростить расширение алгоритмов; +отделить визуализацию от логики поиска; +обеспечить возможность добавления новых форматов данных и алгоритмов. + +Без использования паттернов код был бы менее структурирован и сложнее в сопровождении. + +9. Вывод + +В рамках работы была реализована система поиска пути в лабиринте с возможностью выбора алгоритма и анализа их эффективности. + +Применение паттернов Builder, Strategy, Observer и Command позволило создать гибкую и расширяемую архитектуру. Экспериментальная часть показала, что выбор алгоритма существенно влияет на количество посещённых клеток и время выполнения. \ No newline at end of file diff --git a/nehoroshevaa/docs/report_1.docx

дереве поиска (BST) порядок добавления элементов определяет форму дерева. Если данные поступают в случайном порядке, дерево получается примерно сбалансированным: высота ~ O(log N), и вставка выполняется за O(log N) в среднем. + +Если же данные отсортированы (по возрастанию или убыванию), каждый новый элемент становится либо самым правым, либо самым левым потомком. Дерево вырождается в линейный связный список (так называемое "вырожденное дерево"). В этом случае вставка каждого нового элемента требует прохода по всем уже вставленным узлам, то есть O(N) на операцию. Суммарная вставка N элементов – O(N²). В эксперименте для отсортированного режима BST будет работать значительно медленнее, чем для случайного. + +В моей реализации bst_insert итеративная, но алгоритм сохраняет эту зависимость: при отсортированных именах (User_00000, User_00001, …) каждый новый ключ больше всех предыдущих, поэтому поиск места вставки каждый раз обходит всю текущую цепочку правых потомков, что приводит к квадратичной сложности. + +Хеш‑таблица вычисляет индекс (хеш) от имени и сразу помещает запись в соответствующую корзину. Порядок поступления данных никак не влияет на значение хеша и распределение по корзинам. Даже если имена идут подряд (отсортированы), хеш‑функция (например, (h*31 + ord(ch)) % size) рассеивает их по разным индексам почти равномерно. Поэтому время вставки, поиска и удаления остаётся O(1) в среднем (с учётом разрешения коллизий цепочками), независимо от того, отсортированы данные или перемешаны. + +В связном списке поиск элемента по имени требует последовательного просмотра узлов от головы до тех пор, пока не найдётся нужный или не достигнут конец. В худшем случае (элемент отсутствует или находится в конце) нужно проверить все N узлов. Сложность поиска – O(N) в среднем. Никакая предобработка или порядок вставки не улучшают этот показатель, потому что структура не поддерживает эффективного индексирования. Даже если список отсортировать вручную (но у нас нет сортировки при вставке), поиск останется линейным, так как нельзя выполнить бинарный поиск без возможности прямого доступа по индексу. + +· Связный список: удаление узла по имени требует линейного поиска (O(N)). Найденный узел исключается перенаправлением указателя предыдущего узла на следующий. Для удаления головы – особая обработка. В моей реализации ll_delete возвращает новую голову. Время – O(N). +· Хеш‑таблица: удаление сводится к вычислению индекса корзины (O(1)) и вызову ll_delete для связного списка этой корзины. Средняя длина цепочки – N / bucket_count (обычно небольшая константа). Поэтому удаление в среднем O(1). В коде: buckets[idx] = ll_delete(buckets[idx], name). +· BST: удаление сложнее. Сначала ищется узел (O(log N) в сбалансированном дереве, O(N) – в вырожденном). Если узел найден, то: + · Нет потомков – просто удаляем. + · Один потомок – заменяем удаляемый узел на потомка. + · Два потомка – находим минимальный узел в правом поддереве (или максимальный в левом), копируем его данные в удаляемый узел, затем рекурсивно удаляем этот минимальный узел. + Моя реализация bst_delete рекурсивна, сложность совпадает со сложностью поиска. Для сбалансированного дерева – O(log N), для вырожденного – O(N). + +· Связный список – использовать, только если нужны частые вставки/удаления в начало/конец (например, очередь или стек) и поиск почти не требуется. Для телефонного справочника он не пригоден из-за линейного поиска. +· Хеш‑таблица – идеальный выбор для задач, где важны быстрые вставка, поиск и удаление по ключу (O(1) в среднем) и не требуется получать записи в отсортированном порядке. Примеры: словари, кэши, таблицы символов, базы данных «ключ‑значение». Телефонный справочник с частыми поисками по имени – отличное + + +· BST (особенно самобалансирующиеся варианты, такие как AVL или красно‑чёрное дерево) – выбирают, когда нужны обе возможности: быстрый поиск (O(log N)) и возможность прохода по данным в отсортированном порядке без дополнительной сортировки. Также дерево может поддерживать операции поиска диапазона («все имена между A и B»). Но для простого справочника без требования сортировки на лету хеш‑таблица обычно предпочтительнее из-за константного времени. В данной реализации простой BST деградирует на упорядоченных данных, поэтому в реальной жизни используют сбалансированные деревья. + +Вывод: Если нужен только доступ по ключу – хеш‑таблица. Если нужен отсортированный вывод или диапазонные запросы – сбалансированное дерево. Связный список для этой задачи неприменим. \ No newline at end of file diff --git a/novikovsd/docs/comparison.png b/novikovsd/docs/comparison.png new file mode 100644 index 00000000..f5391f34 Binary

Сравнение алгоритмов поиска +BFS (поиск в ширину) – гарантирует кратчайший путь по числу шагов. Однако на больших лабиринтах требует много памяти и времени из-за обхода всех уровней. Посещает большое количество клеток (например, на large – 8450 клеток). +DFS (поиск в глубину) – очень быстр по времени (минимальное среди всех), но находит очень длинный путь (в 9 раз длиннее BFS на large). Посещает значительно меньше клеток, чем BFS, так как идёт вглубь и выходит при первом нахождении выхода. +A* – компромиссный вариант: находит кратчайший путь (как BFS), но посещает существенно меньше клеток (3100 против 8450 у BFS на large). Время занимает промежуточное значение. На пустом лабиринте A* посещает вдвое меньше клеток, чем BFS/DFS, благодаря направленному поиску. + +Вывод по эффективности: +Если требуется абсолютно кратчайший путь – выбираем BFS (или A*). +Если важна скорость, а длина пути не критична – DFS. +A – лучший баланс* между скоростью, памятью и оптимальностью. + +4.2. Анализ применимости паттернов +Builder позволил отделить формат хранения лабиринта от его внутреннего представления. Если бы вместо TextFileMazeBuilder мы вручную писали парсинг внутри Maze, то добавление JSON-формата потребовало бы изменения класса Maze (нарушение OCP – открытости/закрытости). С Builder'ом достаточно создать JSONMazeBuilder. +Strategy сделала возможным динамическое переключение алгоритмов и упростила добавление нового (например, алгоритм Дейкстры). Без паттерна пришлось бы использовать if-elif и менять код при каждом новом алгоритме. +Observer обеспечил отделение визуализации от логики: MazeSolver не знает, как именно отображается путь, он просто уведомляет подписчиков. Это позволяет легко заменить ConsoleView на GUIView или добавить логирование, не трогая MazeSolver. + +5. Выводы +5.1. Как ООП и паттерны помогли сделать код гибким и расширяемым +Инкапсуляция данных (клетки, лабиринт) – внутренние изменения не влияют на внешний код. +Полиморфизм (интерфейсы MazeBuilder, PathFindingStrategy, Observer) – позволяет взаимозаменять реализации. + +Применение паттернов: +Builder скрыл сложность создания лабиринта – можно добавить новый формат без изменения остальной программы. +Strategy убрал условные операторы при выборе алгоритма – новая стратегия просто добавляет класс. +Observer позволил легко расширить отображение – достаточно подписать новый наблюдатель. + +5.2. Что было бы сложно изменить без паттернов +Переход на другой формат файла лабиринта – пришлось бы переписывать код загрузки, разбросанный по всей программе. +Добавление нового алгоритма поиска – потребовало бы модификации классов-оркестраторов и добавления новых ветвлений if. +Изменение способа визуализации (например, с консоли на графический интерфейс) – без паттерна Observer пришлось бы менять сам MazeSolver, добавляя в него вызовы отрисовки. \ No newline at end of file diff --git a/osininyai/427.md b/osininyai/427.md new file mode 100644 index 00000000..e69de29b diff --git

Введение + +В данной работе были реализованы три структуры данных для хранения телефонного справочника: связный список, хеш-таблица и двоичное дерево поиска. Проведено экспериментальное сравнение производительности операций вставки, поиска и удаления на наборе из **10 000 записей**. + +Для каждой структуры тестирование выполнялось на двух вариантах входных данных: случайный порядок и отсортированный по имени. Каждый эксперимент повторялся **5 раз**, в таблице приведены средние значения. + +## 2.

Анализ результатов + +### 3.1. Влияние порядка данных на BST + +При вставке элементов в отсортированном порядке двоичное дерево поиска вырождается в линейный список. Эксперимент подтверждает это: вставка на отсортированных данных заняла **17.99 секунды**, что в **355 раз** медленнее, чем на случайных данных (0.0507 секунды). Поиск и удаление также замедлились примерно в 500 раз. + +### 3.2. Устойчивость хеш-таблицы к порядку + +Хеш-таблица использует хеш-функцию, которая равномерно распределяет ключи по корзинам независимо от порядка поступления. В случайном и отсортированном режимах время вставки практически одинаково: 0.0218 и 0.0204 секунды. Разница находится в пределах погрешности измерений. + +### 3.3. Медлительность связного списка + +Связный список не обеспечивает прямого доступа к элементам. Вставка 10000 записей заняла **4.84 секунды** в случайном режиме. Время поиска в списке (0.0544 сек) в **278 раз** больше, чем в хеш-таблице (0.000196 сек). Удаление также значительно медленнее. + +### 3.4. Сравнение удаления + +- **Связный список**: 0.0308 сек (случайный) — требуется линейный поиск +- **Хеш-таблица**: 0.000096 сек — практически мгновенно +- **BST на случайных данных**: 0.000175 сек — очень быстро +- **BST на отсортированных данных**: 0.0720 сек — в 400 раз медленнее, чем на случайных + +## 4. Выводы + +**Хеш-таблица** – оптимальный выбор, если требуется максимальная скорость поиска, вставки и удаления. В эксперименте показала стабильно высокую производительность во всех режимах (около 0.02 секунды на вставку 10000 записей). + +**Двоичное дерево поиска** – эффективно на случайных данных, но критически деградирует на отсортированных. При необходимости работы с отсортированными данными следует использовать сбалансированные деревья (AVL, красно-чёрные). + +**Связный список** – практически непригоден для больших объёмов данных из-за линейной сложности (4.84 секунды на вставку 10000 записей). + +**Для телефонного справочника рекомендуется использовать хеш-таблицу** как наиболее быстрое и предсказуемое решение. \ No newline at end of file diff --git a/pogodinda/lab1/hash_table_phonebook.py b/pogodinda/lab1/hash_table_phonebook.py new file mode 100644 index 00000000..4f996f33 --- /dev/null +++ b/pogodinda/lab1/hash_table_phonebook.py @@ -0,0 +1,31 @@ +from linked_list_phonebook import ll_insert, ll_find, ll_delete, ll_list_all + +def hash_function(name, table_size): + hash_value = 0 + for char in name: + hash_value = (hash_value * 31 + ord(char)) % table_size + return hash_value + +def create_hash_table(size=1000): + return [None] * size + +def ht_insert(buckets, name, phone): + index = hash_function(name, len(buckets)) + buckets[index] = ll_insert(buckets[index], name, phone) + +def ht_find(buckets, name): + index = hash_function(name, len(buckets)) + return ll_find(buckets[index], name) + +def ht_delete(buckets, name): + index = hash_function(name, len(buckets)) + buckets[index] = ll_delete(buckets[index], name) + +def ht_list_all(buckets): + all_records = [] + for head in buckets: + if head is not None: + all_records.extend(ll_list_all(head)) + + all_records.sort(key=lambda x: x[0]) + return all_records \ No newline at end of file diff --git a/pogodinda/lab1/linked_list_phonebook.py b/pogodinda/lab1/linked_list_phonebook.py new file mode 100644 index 00000000..69f8421e --- /dev/null +++ b/pogodinda/lab1/linked_list_phonebook.py @@ -0,0 +1,54 @@ +def create_node(name, phone): + return {'name': name, 'phone': phone, 'next': None} + +def ll_insert(head, name, phone): + if head is None: + return create_node(name, phone) + + if head['name'] == name: + head['phone'] = phone + return head + + current = head + while current['next'] is not None: + if current['next']['name'] == name: + current['next']['phone'] = phone + return head + current = current['next'] + + current['next'] = create_node(name, phone) + return head + +def ll_find(head, name): + current = head + while current is not None: + if current['name'] == name: + return current['phone'] + current = current['next'] + return None + +def ll_delete(head, name): + if head is None: + return None + + if head['name'] == name: + return head['next'] + + current = head + while current['next'] is not None: + if current['next']['name'] == name: + current['next'] = current['next']['next'] + return head + current = current['next'] + + return head + +def ll_list_all(head): + records = [] + current = head + while current is not None: + records.append((current['name'], current['phone'])) + current = current['next'] + + records.sort(key=lambda x: x[0]) + return records \ No newline at end of file diff --git a/pogodinda/lab1/plot_results.py b/pogodinda/lab1/plot_results.py new file mode 100644 index 00000000..9925972b --- /dev/null +++ b/pogodinda/lab1/plot_results.py @@ -0,0 +1,96 @@ +import matplotlib.pyplot as plt +import csv +import numpy as np +from collections import defaultdict + +# Читаем результаты из CSV и усредняем по 5 повторам +data = defaultdict(lambda: defaultdict(lambda: defaultdict(list))) + +with open('docs/data/results.csv', 'r', encoding='utf-8') as f: + reader = csv.reader(f) + header = next(reader) # пропускаем заголовок + + # Проверяем, есть ли колонка "Повтор" + has_repeat = 'Повтор' in header + + for row in reader: + struct = row[0] + mode = row[1] + op = row[2] + time_val = float(row[3]) + + # Сохраняем все замеры + data[op][struct][mode].append(time_val) + +# Усредняем +avg_data = {} +for op in data: + avg_data[op] = {} + for struct in data[op]: + avg_data[op][struct] = {} + for mode in data[op][struct]: + times = data[op][struct][mode] + avg_data[op][struct][mode] = sum(times) / len(times) + +# Создаём графики +operations = ['вставка', 'поиск', 'удаление'] +fig, axes = plt.subplots(1, 3, figsize=(15, 5)) + +colors = {'случайный': '#1f77b4', 'отсортированный': '#d62728'} + +for idx, op in enumerate(operations): + ax = axes[idx] + + structures = ['Связный список', 'Хеш-таблица', 'Двоичное дерево'] + data_keys = ['LinkedList', 'HashTable', 'BST'] + + x = np.arange(len(structures)) + width = 0.35 + + random_times = [avg_data[op][key].get('случайный', 0) for key in data_keys] + sorted_times = [avg_data[op][key].get('отсортированный', 0) for key in data_keys] + + bars1 = ax.bar(x -

Цель работы +В этой работе я сделал телефонный справочник на основе трёх структур данных связного списка, хеш таблицы и двоичного дерева поиска. Для каждой структуры нужны были добавление, поиск, удаление и вывод всех записей по алфавиту. после этого я сравнил как они работают на перемешанных и отсортированных данных [сначала казалось что разница будет не такой заметной но после мы увидим что разница есть и в зависимости от задачи и ситуации]. + + Что было реализовано + Связный список +Узел списка хранит имя, телефон и ссылку на следующий элемент. При добавлении запись создаётся или обновляется если такое имя уже есть. Использованы функции ll_insert; ll_find; ll_delete; ll_list_all. [с этой структурой было проще всего начать, потому что логика достаточно прямая] + + Хеш таблица +Хеш таблица сделана как набор ячеек для записей. Для имени вычисляется место куда его сохранить. Если в этом месте уже есть записи они хранятся вместе в связном списке. Использованы функции ht_create; ht_insert; ht_find; ht_delete; ht_list_all. [здесь пришлось отдельно разобраться что делать если несколько имён попадают в одно место. В итоге для таких записей внутри одной ячейки используется связный список] + + Двоичное дерево поиска +В каждом узле дерева хранятся имя, телефон, левый и правый потомок. Записи размещаются по имени поэтому их можно вывести в отсортированном виде. Использованы функции bst_insert; bst_find; bst_delete; bst_list_all. [с удалением в дереве пришлось посидеть дольше всего. Ну если коротко у удаления в дереве несколько случаев: удаляется лист, у узла есть один потомок, у узла есть два потомка, тогда его нужно заменить ближайшим подходящим элементом] + + Проверка работы +В файле tests.py были сделаны простые проверки для всех трёх структур. Я проверил добавление записей; изменение телефона у уже существующего имени; поиск существующей и несуществующей записи; удаление и вывод списка по алфавиту. по результатам запуска всё сработало корректно. [было важно проверить основные операции ещё до замеров] + + Замеры времени +Для сравнения был создан набор из 10000 записей. Использовались два варианта случайный порядок и отсортированный порядок. Для каждой структуры измерялось время вставки всех записей; поиска 110 имён; удаления 50 записей. Каждый замер повторялся 5 раз. Средние значения приведены ниже а полные результаты сохранены в results.csv. [здесь пришлось отдельно разбираться как нормально замерять время. Сначала было не очень понятно как сравнивать структуры честно, потом сделал несколько повторов для каждого случая и считал среднее время] + + Результаты +Связный список; случайный порядок; вставка 17.54 сек; поиск 0.145 сек; удаление 0.086 сек. +Связный список; отсортированный порядок; вставка 15.01 сек; поиск 0.127 сек; удаление 0.074 сек. +Хеш таблица; случайный порядок; вставка 0.896 сек; поиск 0.008 сек; удаление 0.005 сек. +Хеш таблица; отсортированный порядок; вставка 1.253 сек; поиск 0.008 сек; удаление 0.005 сек. +BST; случайный порядок; вставка 0.063 сек; поиск 0.0006 сек; удаление 0.0003 сек. +BST; отсортированный порядок; вставка 23.08 сек; поиск 0.170 сек; удаление 0.097 сек. + + Анализ +По замерам видно что связный список медленно работает при вставке. Перед добавлением новой записи программа идёт по списку и проверяет нет ли уже такого имени. На 10000 записей это уже заметно. Поиск тоже идёт простым перебором. [вот тут стало понятнее почему список быстро начинает тормозить] + +Хеш таблица показала себя намного быстрее. Записи были и перемешанные и уже отсортированные но большой разницы во времени почти не получилось. [этот результат как раз хорошо показал зачем вообще нужна такая структура] + +BST на случайных данных оказался самым быстрым. А вот на отсортированных данных дерево сильно замедлилось. Оно вытягивается почти в одну линию и начинает работать похоже на список. Поэтому вставка заняла около 23 секунд вместо 0.06. [при подготовке замеров стало понятно что на отсортированных данных дерево сильно вытягивается в одну сторону, а старая рекурсивная версия могла плохо отработать на 10000 записей Поэтому часть работы с Бст пришлось переделать без рекурсии] + +!!График среднего времени вставки сохранён в файле graph.png. + + Вывод +Связный список подойдёт для небольшого количества данных но для большого справочника он не очень удобен. Хеш таблица лучше подходит если важны быстрые добавление, поиск и удаление. BST удобно использовать когда нужен вывод записей по порядку но обычное дерево сильно зависит от того в каком порядке добавляются элементы. На отсортированных данных оно работает заметно хуже. в целом работа оказалась не самой простой, местами было довольно запутанно особенно с замерами и деревом на отсортированных данных но в итоге было интересно увидеть насколько по-разному ведут себя разные структуры. \ No newline at end of file diff --git a/raskatovia/docs/task2report.md b/raskatovia/docs/task2report.md new file mode 100644 index 00000000..d78ae3b3 --- /dev/null +++ b/raskatovia/docs/task2report.md @@ -0,0 +1,46 @@ +Цель работы + +В этом задании я сделал программу для поиска пути в лабиринте.

Код является гибким, расширяемым и легко поддерживаемым. + +Эксперименты показали, что **A*** является наиболее сбалансированным алгоритмом для поиска пути в лабиринте, обеспечивая оптимальный путь при приемлемой скорости работы и минимальном количестве посещенных клеток. DFS может быть полезен только когда скорость критична, а оптимальность пути не важна. BFS остается надежным выбором для небольших лабиринтов, где простота реализации важнее производительности. \ No newline at end of file diff --git a/shahovaa/429.md b/shahovaa/429.md new file mode

Анализ эффективности + +BFS гарантирует кратчайший путь в невзвешенном лабиринте. Это видно на маленьком +лабиринте: BFS, A* и Дейкстра нашли путь длиной 20, а DFS нашел более длинный путь +длиной 22. Недостаток BFS - широкий фронт поиска, из-за чего в пустом лабиринте он +посетил все 2304 доступные клетки. + +DFS не гарантирует кратчайший путь, но часто работает быстро, потому что уходит +глубоко по одному направлению. На маленьком лабиринте это дало путь хуже оптимального. +На сгенерированных идеальных лабиринтах путь между двумя клетками единственный, поэтому +DFS, BFS, A* и Дейкстра получили одинаковую длину пути. + +A* использует манхэттенскую эвристику. На пустом лабиринте он посетил только 95 клеток, +то есть фактически прошел по оптимальному маршруту. В запутанных идеальных лабиринтах +эвристика помогает слабее: прямое направление к выходу часто упирается в стены, поэтому +A* посещает почти столько же клеток, сколько BFS, а из-за приоритетной очереди тратит +больше времени. + +Дейкстра в невзвешенном лабиринте по результату близок к BFS, но работает медленнее +из-за приоритетной очереди. Его преимущество проявляется при взвешенных клетках. +В проекте Builder уже поддерживает символы `2`, `3` и `~` как клетки с повышенной +стоимостью прохода, поэтому Дейкстру и A* можно использовать для дополнительного +сравнения на взвешенных картах. + +Лабиринт "Без пути" проверяет корректную обработку отсутствия решения: стратегии +возвращают пустой путь, а `MazeSolver` фиксирует длину 0. + +## 5. Выводы + +ООП позволило разделить предметную модель, загрузку данных, алгоритмы и интерфейс. +Паттерн Builder делает формат входного файла заменяемым: можно добавить JSON-builder, +не меняя `Maze` и стратегии. Strategy позволяет добавлять новые алгоритмы без правок +в `MazeSolver`. Observer отделяет вычисления от вывода, а Command показывает, как +инкапсулировать пользовательские действия и поддержать undo. + +Без этих паттернов код быстро стал бы монолитным: парсинг файла, поиск, статистика, +печать и ручное управление оказались бы в одном месте. Тогда добавление нового формата, +алгоритма или режима отображения требовало бы менять уже работающую логику. diff --git a/shahovaa/zadanie 2/reports/results.csv b/shahovaa/zadanie

Отчет по заданию 1: структуры данных + +## Цель + +Реализовать три структуры данных с нуля в процедурной парадигме и сравнить +скорость основных операций телефонного справочника: + +- `insert(name, phone)` - добавить или обновить запись; +- `find(name)` - найти телефон по имени; +- `delete(name)` - удалить запись; +- `list_all()` - получить все записи, отсортированные по имени. + +Классы не использовались. Узлы связного списка и дерева представлены +словарями, хеш-таблица представлена списком бакетов. + +## Реализация + +Код находится в файле `phonebook.py`. + +Реализованы функции: + +- связный список: `ll_insert`, `ll_find`, `ll_delete`, `ll_list_all`; +- хеш-таблица: `create_hash_table`, `ht_insert`, `ht_find`, `ht_delete`, `ht_list_all`; +- двоичное дерево поиска: `bst_insert`, `bst_find`, `bst_delete`, `bst_list_all`. + +Для хеш-таблицы используется метод цепочек: каждый бакет хранит голову +связного списка. Хеш-функция написана вручную, чтобы результат не зависел от +рандомизации встроенной функции `hash()` в Python. + +Для BST вставка, поиск, удаление и обход написаны без классов. Обход +`bst_list_all` реализован итеративно, чтобы отсортированный вход на 10000 +элементов не приводил к переполнению стека рекурсии. + +## Методика эксперимента + +Скрипт эксперимента находится в файле `benchmark.py`. + +Параметры запуска: + +- количество записей: `N = 10000`; +- число повторов каждого эксперимента: `5`; +- имена: `User_00000`, `User_00001`, ..., `User_09999`; +- два режима входных данных: `shuffled` и `sorted`; +- поиск: 100 существующих имен и 10 отсутствующих; +- удаление: 50 случайных существующих имен; +- размер хеш-таблицы: `20011` бакетов. + +После вставки структура не пересоздается: поиск и удаление выполняются на той +же заполненной структуре.

Причина в том, что +для корректной операции `insert` нужно проверить, есть ли уже запись с таким +именем. При уникальных именах почти каждая вставка проходит по всему текущему +списку, поэтому суммарная сложность вставки всех записей становится `O(n^2)`. +Порядок входных данных почти не влияет на результат, потому что структура не +использует порядок ключей. + +Хеш-таблица показала лучшие результаты почти во всех операциях. При хорошем +распределении по бакетам вставка, поиск и удаление близки к `O(1)`. Порядок +входных данных почти не влияет на время, так как индекс бакета определяется +хешем имени, а не расположением записи во входном списке. + +BST хорошо работает на перемешанных данных: дерево получается сравнительно +сбалансированным, поэтому операции близки к `O(log n)`. На отсортированном +входе обычное двоичное дерево поиска вырождается в цепочку: каждый новый ключ +становится правым потомком предыдущего. Из-за этого вставка всех записей +становится `O(n^2)`, а поиск и удаление приближаются к поведению связного +списка. + +Удаление у хеш-таблицы быстрое по той же причине, что и поиск: сначала +вычисляется бакет, затем просматривается короткая цепочка. В BST удаление +быстрое на перемешанном дереве, но на вырожденном дереве оно замедляется. +В связном списке удаление требует линейного поиска удаляемого элемента. + +## Вывод + +Для частого поиска, обновления и удаления по точному имени лучше выбирать +хеш-таблицу. Она быстрее всего в эксперименте и почти не зависит от порядка +вставки. + +Если нужно часто получать данные в отсортированном порядке, дерево поиска дает +удобный `in-order` обход без отдельной сортировки. Но обычный BST чувствителен +к порядку входных данных, поэтому на практике лучше использовать +самобалансирующееся дерево или готовую структуру из библиотеки. + +Связный список подходит только для маленьких наборов данных или учебных задач. +Для телефонного справочника с частым поиском он неудачен, потому что каждая +операция поиска требует последовательного прохода по элементам. diff --git

Связный список — стабильно низкая скорость + +Вставка требует **~2.5 секунд** на 10 000 элементов, поскольку каждая операция при наличии дубликатов имени вынуждена сканировать весь список O(n). При случайных уникальных именах вставка выполняется в начало за O(1), но **поиск** всё равно линейный. + +**Вывод:** связный список непригоден для частого поиска в больших объёмах данных, но удобен как вспомогательный элемент (например, для цепочек в хеш-таблице). + +### 2. Хеш-таблица — устойчивость к порядку входных данных + +Хеш-таблица продемонстрировала **практически идентичные результаты** в обоих режимах: +- Вставка: ~0.017 с (быстрее списка в ~150 раз) +- Поиск: ~0.0002 с (быстрее списка в ~160 раз) + +Хеш-функция равномерно распределяет ключи независимо от порядка их поступления, поэтому производительность остаётся стабильной. + +### 3. BST катастрофически деградирует на упорядоченных данных + +Наиболее показательный результат эксперимента: + +| | Случайный | Сортированный | Ухудшение | +|---|---|---|---| +| BST insert | 0.017 с | **3.854 с** | **×225** | +| BST find | 0.000145 с | **0.033 с** | **×231** | + +**Причина:** при вставке отсортированных данных дерево вырождается в линейный список — каждый новый элемент оказывается больше предыдущего и помещается только в правую ветку. Высота дерева становится O(n) вместо O(log n), что превращает все операции в линейные. + +### 4. Операция delete + +На случайных данных BST удаляет за **~0.0001 с** (логарифмическая сложность). На сортированных — **~0.046 с** (линейная деградация). HashTable показывает стабильные **~0.00012 с** независимо от порядка. + +--- + +## Выводы и практические рекомендации + +### Выбор структуры в зависимости от задачи + +| Сценарий | Рекомендация | +|---|---| +| **Частый поиск по ключу** | HashTable или BST (случайный порядок) | +| **Данные поступают упорядоченно** | HashTable (BST непригоден) | +| **Требуется отсортированный вывод** | BST (обход даёт порядок за O(n)) | +| **Интенсивные вставки/удаления + поиск** | HashTable | +| **Ограниченный объём данных, простота** | LinkedList (до сотен элементов) | +| **Диапазонные запросы** (например, A–M) | BST | + +### Теоретическая сложность операций + +| Структура | Insert | Find | Delete | Обход (отсорт.) | +|---|---|---|---|---| +| LinkedList | O(n) | O(n) | O(n) | O(n log n) | +| HashTable | O(1) в среднем | O(1) в среднем | O(1) в среднем | O(n log n) | +| BST (сбалансированный) | O(log n) | O(log n) | O(log n) | O(n) | +| BST (вырожденный) | O(n) | O(n) | O(n) | O(n) | + +### Ключевой вывод + +Для телефонного справочника с частыми поисками и обновлениями оптимальный выбор — **хеш-таблица**. BST выигрывает только при необходимости получать отсортированные данные без дополнительной сортировки, но требует либо случайного порядка вставки, либо использования самобалансирующихся вариантов

Алгоритм поиска выбирается динамически, результаты выводятся через систему событий. + +Применены **4 паттерна GoF**: Builder, Strategy, Observer, Command. + +### 1. Builder (Строитель) — `maze_builder.py` + +**Проблема:** построение объекта `Maze` из файла — многошаговый процесс: открыть файл, разобрать символы, создать объекты `Cell`, установить координаты, найти старт и выход, собрать двумерный массив. Смешивать это с основной логикой нельзя. + +**Решение:** интерфейс `MazeBuilder` с единственным методом `build_from_file(filename)` и реализация `TextFileMazeBuilder`, инкапсулирующая весь парсинг. + +**Преимущество без паттерна было бы сложно:** при добавлении поддержки JSON-лабиринтов пришлось бы встраивать ветвление прямо в клиентский код. С Builder — просто создаём `JsonFileMazeBuilder` и подставляем без изменений в остальном коде. + +### 2. Strategy (Стратегия) — `maze_strategies.py` + +**Проблема:** алгоритмы BFS, DFS и A* принципиально различаются по реализации, но выполняют одну задачу — найти путь. Жёсткое встраивание алгоритма в `MazeSolver` делало бы переключение невозможным без правки класса. + +**Решение:** интерфейс `PathFindingStrategy` с методом `find_path(maze, start, exit)`. Каждый алгоритм реализует интерфейс независимо. `MazeSolver.set_strategy()` меняет алгоритм в одну строку во время выполнения. + +**Преимущество без паттерна было бы сложно:** добавление Dijkstra или любого нового алгоритма потребовало бы правки `MazeSolver`. С Strategy — новый алгоритм добавляется одним классом, остальной код не меняется. + +### 3. Observer (Наблюдатель) — `maze_solver.py` + +**Проблема:** `MazeSolver` должен уведомлять интерфейс о событиях (путь найден, лабиринт загружен), но не должен знать, кто именно получает эти уведомления. + +**Решение:** интерфейс `Observer` с методом `update(event, data)`. `ConsoleView` реализует интерфейс и подписывается на `MazeSolver`. При наступлении события вызывается `_notify()`, который обходит список подписчиков. + +**Преимущество без паттерна было бы сложно:** прямой вызов `ConsoleView` из `MazeSolver` создаёт жёсткую зависимость. С Observer — `ConsoleView` можно отключить, заменить на GUI или добавить файловый логгер без единой правки в `MazeSolver`. + +### 4. Command (Команда) — `maze_solver.py` + +**Проблема:** для пошагового режима нужно перемещать игрока с возможностью отмены хода. + +**Решение:** интерфейс `Command` с методами `execute()` и `undo()`. `MoveCommand` хранит целевую клетку и предыдущую позицию игрока. История команд — обычный стек. + +**Преимущество без паттерна было бы сложно:** прямое изменение позиции игрока не сохраняет историю. С Command — `undo()` возвращает игрока на шаг назад, а добавление новых типов действий (атака, открыть дверь) не требует изменения `Player`. + +--- + +## Диаграмма классов (Mermaid) + +```mermaid +classDiagram + class MazeBuilder { + <> + +build_from_file(filename) Maze + } + class TextFileMazeBuilder { + +build_from_file(filename) Maze + } + class Maze { + -int width, height + -Cell[][] cells + -Cell start + -Cell exit + +get_cell(x, y) Cell + +get_neighbors(cell) list + +render(path, player_pos) + } + class Cell { + -int x, y + -bool is_wall + -bool is_start + -bool is_exit + +is_passable() bool + } + class PathFindingStrategy { + <> + +find_path(maze, start, exit) list + } + class BFSStrategy { +find_path() } + class DFSStrategy { +find_path() } + class AStarStrategy { +find_path() } + class MazeSolver { + -Maze maze + -PathFindingStrategy strategy + -list observers + +set_strategy(strategy) + +add_observer(observer) + +solve() SearchStats + } + class SearchStats { + +float time_ms + +int visited_cells + +int path_length + +list path + } + class Observer { + <> + +update(event, data) + } + class ConsoleView { +update(event, data) } + class Command { + <> + +execute() + +undo() + } + class MoveCommand { + -Player player + -Cell target_cell + -Cell previous_cell + +execute() + +undo() + } + class Player { + -Cell current_cell + +move_to(cell) + } + + MazeBuilder <|..

Корректность обработки этого случая — важный результат: каждый алгоритм возвращает пустой список, а не зависает. + +### Лабиринт без выхода (20×20) + +Все алгоритмы обошли все 260 доступных клеток и корректно вернули пустой путь. A* в этом сценарии чуть медленнее (0.607 мс против 0.368 мс у BFS) — приоритетная очередь имеет накладные расходы O(log n) на каждую операцию. + +--- + +## Выводы + +### Эффективность алгоритмов в разных сценариях + +| Задача | Рекомендация | Обоснование | +|---|---|---| +| Кратчайший путь | BFS или A* | Оба гарантируют оптимум | +| Большой лабиринт с препятствиями | A* | В 2–3 раза меньше посещённых клеток | +| Открытое пространство | BFS | A* теряет преимущество без отсечений | +| Нужен любой путь быстро | DFS | Меньше клеток, меньше накладных расходов | +| Недостижимый выход | Любой | Все алгоритмы корректно завершаются | + +### Применимость паттернов + +**Strategy** — самый ценный паттерн в данной задаче. Именно он позволяет запускать три алгоритма через единый интерфейс в цикле бенчмарка без дублирования кода. Добавление четвёртого алгоритма (Dijkstra) займёт ~30 строк без правок в `MazeSolver` или `benchmark.py`. + +**Builder** оправдал себя при добавлении пяти разных лабиринтов: клиентский код (`benchmark.py`) не менялся, только передавался другой файл. Без Builder парсинг был бы размазан по всему коду. + +**Observer** отделил вывод от логики: в бенчмарке `ConsoleView` не подключается вовсе, чтобы не засорять вывод. В интерактивном режиме подключается одной строкой. + +**Command** демонстрирует принцип undo/redo: без него отмена хода требовала бы хранения копии состояния снаружи объекта `Player`. С Command история инкапсулирована в стеке команд. + +### Общий вывод + +ООП и паттерны проектирования сделали код модульным и расширяемым. Каждый класс решает одну задачу. Изменение любого компонента (алгоритм, формат файла, интерфейс) не ломает остальные части программы — это и есть практическая ценность паттернов GoF. diff --git a/shapovalovka/425.txt

Модель лабиринта + +В первом этапе разработки необходимо создать базовые классы `Cell` и `Maze`, которые представляют карту лабиринта. Паттерны на этом этапе не применяются — только чистые классы. + +## Класс `Cell` + +Клетка — минимальная единица лабиринта. Хранит координаты и тип: стена, старт, выход или пустая. + +По условию задания клетка должна иметь флаги `isWall`, `isStart`, `isExit` и метод `isPassable()`. В реализации флаги оформлены как **свойства** (`@property`) с сеттерами — это позволяет автоматически сбрасывать остальные флаги при установке нового типа. + +```python +cell = Cell(1, 1) +cell.is_wall = True +``` + +Типы клетки взаимоисключают друг друга — клетка не может быть одновременно стеной и стартом. Логика сброса вынесена в приватный метод `_clear_flags()`. + +### Символьное представление + +Для вывода лабиринта в консоль каждая клетка возвращает символ через `__str__`. Символы берутся из `cell_mapping` в `source/settings.py`, что позволяет менять отображение без правки классов: + +| Тип | Символ по умолчанию | +|--------|-----------------------| +| Стена | `#` | +| Старт | `S` | +| Выход | `E` | +| Пустая | | + +## Класс `Maze` + +Лабиринт хранит двумерный список клеток и предоставляет методы для работы с ними. + +По условию задания требовались методы `getCell(x, y)` и `getNeighbors(cell)`. В реализации добавлено несколько вещей сверх задания: + +### Именование методов + +Задание написано в стиле Java/pseudocode — названия методов и полей используют `camelCase` (`isWall`, `getCell`, `isPassable`). В Python принят другой стандарт именования — **PEP 8**, который предписывает `snake_case` для методов и атрибутов. Поэтому все названия были приведены к Python стилю: + +| Задание | Реализация | +|---------------------------|-----------------------------| +| `isWall` | `is_wall` | +| `isStart` | `is_start` | +| `isExit` | `is_exit` | +| `isPassable()` | `is_possible()` | +| `getCell(x, y)` | `get_cell(x, y)` | +| `getNeighbors(cell)` | `get_neighbors(x, y)` | +| `buildFromFile(filename)` | `build_from_file(filename)` | + +Это соответствует стандарту оформления кода на Python и делает API классов идиоматичным для языка. + +### Индексация `maze[row, col]` + +Вместо явного вызова `get_cell()` реализованы `__getitem__` и `__setitem__`, что позволяет обращаться к клеткам естественным образом: + +```python +maze[0, 0] = cell_mapping['wall'] # установить стену +cell = maze[2, 3] # получить клетку +``` + +Обратите внимание: индексация идёт в формате `[row, col]`, то есть сначала строка (Y), потом столбец (X) — аналогично numpy. + +### Свойства `start` и `exit` + +Добавлены свойства для быстрого получения стартовой и выходной клетки без ручного обхода: + +```python +maze.start # Cell или None +maze.exit # Cell или None +``` + +Это оказалось необходимым при реализации алгоритмов поиска пути — стратегии получают `start` и `exit` автоматически из лабиринта. + +### Свойство `shape` + +По аналогии с numpy добавлено свойство `shape`, возвращающее `(height, width)`: + +```python +rows, cols = maze.shape +``` + +Используется в стратегиях поиска и тестах для итерации по лабиринту. + +### `get_neighbors` + +Метод возвращает список проходимых соседей клетки по четырём направлениям. Стены и клетки за границей лабиринта исключаются автоматически. Если переданные координаты вне границ — возвращает `None`. + +```python +neighbors = maze.get_neighbors(2, 2) # список Cell +``` + +Направления обхода: вниз → вправо → вверх → влево (порядок влияет на поведение DFS). +# Этап 2. Загрузка лабиринта из файла + +Во втором этапе реализована загрузка лабиринта из текстового файла с применением паттерна **Builder**. + +## Паттерн Builder + +Процесс создания лабиринта из файла включает несколько шагов: чтение файла, валидацию структуры, парсинг символов и заполнение клеток. Builder скрывает эти детали от клиента — снаружи виден только один метод `build_from_file()`, внутри которого сосредоточена вся логика построения. + +Дополнительное преимущество: в будущем можно легко добавить новый формат (например, JSON или бинарный) через новую реализацию `MazeBuilder` без изменения остального кода. + +## Класс `MazeBuilder` + +Абстрактный базовый класс — интерфейс паттерна Builder. Объявляет единственный метод `build_from_file()`, который обязан реализовать каждый конкретный строитель. + +По условию задания интерфейс назывался `MazeBuilder` с методом `buildFromFile`. В реализации название метода приведено к **PEP 8** — `build_from_file`. Сам класс оформлен через `ABC` — попытка создать объект `MazeBuilder()` напрямую вызовет `TypeError`. + +## Класс `TextFileBuilder` + +Конкретная реализация строителя для текстовых файлов. Загружает лабиринт из `.txt` файла где `#` — стена, — проход, `S` — старт, `E` — выход. + +Процесс построения разбит на три приватных шага: + +### `_read_file` + +Читает файл построчно и обрезает символы переноса строки `\n` и `\r`. Возвращает список строк — каждая строка соответствует одной строке лабиринта. + +### `_test_text_maze` + +Валидирует структуру: проверяет что все строки одинаковой длины. Если нет — лабиринт некорректен и `_create_maze` выбросит `ValueError`. + +Реализован как `@staticmethod` — не использует состояние объекта, только входные данные. + +### `_create_maze` + +Создаёт объект `Maze` нужного размера и заполняет его клетки символами из файла через `maze[y, x] = symbol`. Тип каждой клетки определяется автоматически через `cell_mapping` в `__setitem__` лабиринта. + +## Использование + +```python +from source.build.builder import TextFileBuilder + +maze = TextFileBuilder().build_from_file('source/templates/10x10_path_v1.txt') +print(maze) +``` + +## Известная ошибка + +В текущей реализации `_create_maze` есть опечатка при вычислении `width`: + +```python +height, width = len(text_maze), len(text_maze) # width всегда равен height +``` + +Правильная версия: + +```python +height, width = len(text_maze), len(text_maze[0]) +``` + +На квадратных лабиринтах (10×10, 50×50) это не проявляется, но на прямоугольных даст некорректный результат. +# Этап 3. Стратегии поиска пути + +В третьем этапе реализованы алгоритмы поиска пути с применением паттерна **Strategy**. + +## Паттерн Strategy + +Все три алгоритма реализуют один интерфейс `PathFindingStrategy`. Это позволяет переключать алгоритм в любой момент без изменения кода клиента — достаточно передать другой объект стратегии: + +```python +solver = MazeSolver(maze, BFSStrategy()) +solver.set_strategy(AStarStrategy()) +``` + +Новый алгоритм добавляется реализацией интерфейса — остальной код трогать не нужно. + +## Структура пакета + +Стратегии разбиты по отдельным файлам, а `__init__.py` собирает всё в один импорт: + +```default +source/strategy/ +├── __init__.py ← единственный импорт для пользователя +├── algorithms.py ← базовый класс PathFindingStrategy +├── bfs.py +├── dfs.py +└── astar.py +``` + +```python +from source.strategy import BFSStrategy, DFSStrategy, AStarStrategy +``` + +## Класс `PathFindingStrategy` + +Абстрактный базовый класс — интерфейс паттерна. Объявляет абстрактный метод `find_path()` и содержит два вспомогательных метода, общих для всех стратегий. + +По условию задания метод назывался `findPath` — приведён к **PEP 8** как `find_path`. + +### `_validate` + +Добавлен в процессе разработки — изначально в задании не было требования к обработке отсутствия старта или выхода. Проблема проявилась при тестировании лабиринтов типа `noexit`: алгоритм падал с `AttributeError` внутри, вместо понятного сообщения. + +`_validate` подставляет `start` и `exit` из лабиринта если они не переданы явно, и выбрасывает `ValueError` с понятным сообщением если клетки не найдены: + +```python +start, exit = self._validate(maze, start, exit) +``` + +Вынесен в базовый класс чтобы не дублировать в каждом алгоритме. + +### `_reconstruct_path` + +Восстанавливает путь по словарю предков `came_from`. Все три алгоритма строят этот словарь одинаково — `{клетка: откуда_пришли}` — поэтому восстановление вынесено в общий метод базового класса. + +Алгоритм идёт от выхода к старту по цепочке предков, затем разворачивает список: + +```default +exit → D → C → B → start (идём по came_from) +start → B → C → D → exit (после reverse) +``` + +## Алгоритмы + +### BFS — `BFSStrategy` + +Поиск в ширину. Использует `deque` как очередь (FIFO) — каждый раз берём самую старую клетку из начала. Это гарантирует послойный обход и кратчайший путь по количеству шагов. + +Сложность: O(V + E) по времени и памяти. + +### DFS — `DFSStrategy` + +Поиск в глубину. Использует `list` как стек (LIFO) — каждый раз берём самую свежую клетку с конца. Алгоритм ныряет вглубь по одному направлению до тупика, затем возвращается. + +Не гарантирует кратчайший путь. На запутанных лабиринтах может обойти почти все клетки прежде чем найти выход, хотя по времени часто быстрее BFS из-за меньших накладных расходов на структуру данных. + +Сложность: O(V + E) по времени и памяти. + +### A\* — `AStarStrategy` + +Использует `heapq` как приоритетную очередь. На каждом шаге выбирает клетку с минимальным значением `f = g + h`, где `g` — стоимость пути от старта, `h` — манхэттенская эвристика до выхода. + +Эвристика направляет поиск в сторону выхода, поэтому A\* обходит меньше клеток чем BFS при том же гарантированно кратчайшем пути. + +В кортеж приоритетной очереди добавлен счётчик `counter` как tie-breaker — без него `heapq` попытался бы сравнивать объекты `Cell` при одинаковом `f`, что вызвало бы `TypeError`: + +```python +heapq.heappush(open_heap, (f, counter, neighbor)) +``` + +Сложность: O(E · log V) в худшем случае. +# Этап 4. Класс-оркестратор MazeSolver + +В четвёртом этапе реализован класс `MazeSolver`, который объединяет лабиринт и стратегию поиска, выполняет поиск и собирает статистику. + +## Роль в архитектуре + +`MazeSolver` — точка входа для клиентского кода. Он не знает деталей ни одного алгоритма и не работает напрямую с клетками лабиринта — только делегирует задачу стратегии и замеряет время: + +```python +solver = MazeSolver(maze, BFSStrategy()) +stats = solver.solve() +print(stats) +# Время: 0.041 мс | Посещено клеток: 13 | Длина пути: 13 +``` + +## Класс `SearchStats` + +Оформлен через `@dataclass` — это избавляет от ручного `__init__` и автоматически даёт `__repr__`. Хранит четыре поля: время выполнения, количество посещённых клеток, длину пути и сам путь как список клеток. + +`__str__` переопределён для удобного вывода в консоль и отчётах. + +### Ограничение + +В текущей реализации `visited_count` и `path_length` всегда равны друг другу — оба вычисляются как `len(path)`. Это потому что стратегии возвращают только финальный путь, а не все посещённые клетки. Чтобы получить точное количество посещений, потребовалось бы дорабатывать каждую стратегию — добавлять счётчик внутри `find_path`. На данном этапе это сознательное упрощение. + +## Класс `MazeSolver` + +### `set_strategy` + +Позволяет менять алгоритм без пересоздания солвера. Это и есть основная демонстрация паттерна Strategy в действии — один объект, разные алгоритмы: + +```python +solver = MazeSolver(maze, BFSStrategy()) +stats_bfs = solver.solve() + +solver.set_strategy(AStarStrategy()) +stats_astar = solver.solve() +``` + +### `solve` + +Замеряет время через `time.perf_counter()` — самый точный таймер в Python для коротких интервалов, не зависящий от системных часов. Результат переводится в миллисекунды умножением на 1000. + +`start` и `exit` можно не передавать — стратегия найдёт их сама через `_validate`. Явная передача нужна только если хочется запустить поиск не от стандартного старта, а от произвольной клетки. +# Этап 5. Визуализация и пошаговое управление + +В пятом этапе реализованы два паттерна: **Observer** для отображения событий и **Command** для пошагового управления игроком. + +## 5.1. Паттерн Observer + +### Идея + +`MazeSolver` и игровой цикл не знают как именно отображать происходящее — они просто генерируют события. Наблюдатели подписываются на эти события и реагируют по своему усмотрению. Это позволяет в будущем добавить, например, `FileLogger` или графический интерфейс без изменения основного кода. + +### Класс `Event` + +Оформлен через `@dataclass`. Хранит тип события строкой и словарь `payload` с дополнительными данными. Поддерживаются четыре типа событий: + +| Тип | Когда генерируется | +|---------------|----------------------------| +| `maze_loaded` | Лабиринт загружен из файла | +| `path_found` | Алгоритм нашёл путь | +| `no_path` | Путь не найден | +| `move` | Игрок сделал ход | + +### Класс `Observer` + +Абстрактный базовый класс с единственным методом `update(event)`. Любой наблюдатель обязан его реализовать. + +### Класс `ConsoleView` + +Конкретная реализация наблюдателя. Обрабатывает события через `match/case` и вызывает `render()` для перерисовки лабиринта. + +Метод `render()` принимает лабиринт, опциональную позицию игрока и опциональный путь. Путь преобразуется в `set` для быстрой проверки принадлежности клетки — это O(1) вместо O(n) при каждом обходе: + +```python +path_set = set(path) if path else set() +``` + +Лабиринт обрамляется рамкой из `+` и `─` для читаемости в консоли. Символы игрока и пути вынесены в константы класса — легко поменять без правки логики: + +```python +PLAYER_SYMBOL = "P" +PATH_SYMBOL = "·" +``` + +## 5.2. Паттерн Command + +### Идея + +Каждое перемещение игрока оборачивается в объект `MoveCommand`. Это позволяет сохранить предыдущее состояние и отменить ход — реализация `undo` становится тривиальной. + +### Класс `Player` + +Простой контейнер для текущей клетки игрока. Намеренно минималистичный — вся логика перемещения и проверок находится в команде, а не в игроке. + +### Класс `Command` + +Абстрактный интерфейс с двумя методами: `execute()` и `undo()`. `execute()` возвращает `bool` — это отличие от классического варианта паттерна, где команды не возвращают значений. Возврат `False` нужен чтобы не добавлять неуспешный ход в историю. + +### Класс `MoveCommand` + +Хранит ссылку на игрока, направление и лабиринт. При `execute()` проверяет проходимость целевой клетки, сохраняет текущую в `_prev_cell` и перемещает игрока. При `undo()` восстанавливает `_prev_cell`. + +Направления вынесены в словарь `DIRECTIONS` на уровне модуля: + +```python +DIRECTIONS = { + "w": (0, -1), # вверх + "s": (0, 1), # вниз + "a": (-1, 0), # влево + "d": (1, 0), # вправо +} +``` + +### Класс `CommandHistory` + +Стек выполненных команд. Хранит только успешные ходы — неуспешные (`execute()` вернул `False`) в историю не добавляются. `undo()` снимает последнюю команду со стека и вызывает её `undo()`. + +Пример игрового цикла: + +```python +cmd = MoveCommand(player, 'd', maze) +if cmd.execute(): + history.push(cmd) # добавляем только успешный ход + +history.undo() # отмена последнего хода +``` +# Этап 6. Экспериментальная часть + +В шестом этапе проведено сравнение эффективности трёх стратегий поиска пути на лабиринтах разной сложности. Эксперимент реализован в Jupyter Notebook (`practice/main.ipynb`). + +## Подготовка + +Лабиринты загружаются из папки `source/templates` автоматически — все файлы считываются через `os.listdir` и передаются в `TextFileBuilder`. Стратегии собраны в словарь для удобной итерации: + +```python +strategies = { + "BFS": BFSStrategy(), + "DFS": DFSStrategy(), + "A*": AStarStrategy(), +} +``` + +## Замеры + +Каждая пара лабиринт + стратегия запускается **10 раз**, результаты усредняются. Это сглаживает разброс из-за кэширования и фоновой активности системы. + +Лабиринты типа `noexit` пропускаются автоматически — стратегия выбрасывает `ValueError`, который перехватывается через `try/except`, и выполнение продолжается. + +Результаты собираются в список словарей и затем преобразуются в `DataFrame` через pandas. + +## Результаты + +### 10×10 (простой путь) + +На маленьких лабиринтах все три алгоритма показывают практически одинаковое время (~0.03–0.07 мс) и одинаковую длину пути. Разница незначительна — лабиринт слишком мал чтобы эвристика A\* давала преимущество. + +### 50×50 (тупики) + +BFS стабильно быстрее DFS по времени при одинаковой длине пути. DFS заходит в каждый тупик до конца и тратит время на возврат, хотя финальный путь совпадает. A\* показывает время между BFS и DFS. + +### 100×100 (запутанный, spaghetti) + +Наиболее показательные результаты: + +| Стратегия | Время (мс) | Длина пути | +|-------------|--------------|--------------| +| BFS | ~9 | ~210 | +| DFS | ~7 | ~2200 | +| A\* | ~8 | ~210 | + +DFS быстрее по времени, но находит путь в 10 раз длиннее — обходит почти весь лабиринт. BFS и A\* находят кратчайший путь, A\* при этом чуть быстрее за счёт эвристики. + +### 30×30 (пустой) + +Неожиданный результат: DFS быстрее всех (~0.73 мс против 1.1 у BFS и 2.0 у A\*), хотя находит путь из 379 клеток против 55 у BFS. На пустом поле без стен DFS сразу уходит вглубь без возвратов, тогда как BFS строит очередь и обходит клетки волнами во все стороны — это накладные расходы на структуру данных. + +A\* на пустом лабиринте медленнее всех — накладные расходы на `heapq` и вычисление эвристики не окупаются когда препятствий нет. + +## Выводы + +- **BFS** — надёжный выбор по умолчанию. Всегда находит кратчайший путь, время предсказуемо. +- **DFS** — быстрый по времени, но путь непредсказуем. На запутанных лабиринтах может пройти весь граф. Подходит когда важна скорость, а не оптимальность пути. +- **A**\* — лучший выбор для больших лабиринтов с препятствиями. Находит кратчайший путь быстрее BFS за счёт эвристики. На простых или пустых лабиринтах проигрывает из-за накладных расходов на приоритетную очередь. + +## Визуализация + +![[results.png]] +# Этап 7. Отчёт + +## Описание задачи + +Разработать программу для загрузки лабиринта из файла, поиска пути с выбором алгоритма и сравнения их эффективности. Применены четыре паттерна GoF: + +| Паттерн | Где применён | +|--------------|-----------------------------------------------| +| **Builder** | `TextFileBuilder` | +| **Strategy** | `BFSStrategy`, `DFSStrategy`, `AStarStrategy` | +| **Observer** | `ConsoleView` | +| **Command** | `MoveCommand`, `CommandHistory` | + +## Диаграмма классов + +## Результаты экспериментов + +| Лабиринт | Быстрее всех | Кратчайший путь | +|-------------------|----------------|-------------------| +| 10×10 path | все одинаково | все одинаково | +| 50×50 deadends | BFS | BFS = A\* | +| 100×100 spaghetti | DFS | BFS = A\* | +| 30×30 empty | DFS | BFS = A\* | + +- **BFS** — надёжный выбор, всегда кратчайший путь. +- **DFS** — быстрый, но путь длиннее. На 100×100 обошёл в 10 раз больше клеток. +- **A\*** — лучший на больших лабиринтах с препятствиями, проигрывает на простых из-за накладных расходов на `heapq`. + +## Выводы + +Паттерны сделали код расширяемым: новый алгоритм — один класс, новый формат файла — один класс, новый способ отображения — один класс. Без паттернов каждое такое изменение потребовало бы правки существующего кода. +# Задание + +## Цель работы + +Разработать гибкую, расширяемую программу для загрузки лабиринта из файла, поиска пути от старта до выхода с возможностью выбора алгоритма, визуализации процесса и экспериментального сравнения алгоритмов. В ходе работы необходимо применить минимум 3 паттерна проектирования из списка GoF, обосновать их выбор и продемонстрировать преимущества такой архитектуры. + +## Общая схема приложения (пример) + +## Выполнение + +### Этап 1. Модель лабиринта (без паттернов, просто классы) + +**Задача:** Создать классы `Cell` и `Maze`, которые представляют карту лабиринта. + +- `Cell` хранит координаты (x, y), флаги `isWall`, `isStart`, `isExit`, метод `isPassable()` (возвращает `True` для прохода, если не стена). +- `Maze` хранит двумерный массив клеток, ширину, высоту, ссылки на стартовую и выходную клетку. Методы: `getCell(x, y)`, `getNeighbors(cell)` – возвращает список соседних проходимых клеток (вверх, вниз, влево, вправо, если в пределах границ и не стена). + +**Результат:** Лабиринт можно создать вручную в коде, но загрузку пока не делаем. + +### Этап 2. Загрузка лабиринта из файла – применение паттерна **Builder** + +**Задача:** Реализовать загрузку лабиринта из текстового файла, где `#` – стена, ` ` (пробел) – проход, `S` – старт, `E` – выход. + +- Создать интерфейс `MazeBuilder` с методом `buildFromFile(filename)`. +- Реализовать класс `TextFileMazeBuilder`, который читает файл, парсит символы, создаёт объекты `Cell`, задаёт координаты и флаги, после чего возвращает готовый `Maze`. + +Процесс построения лабиринта сложный (парсинг, валидация, установка старта/выхода). Builder скрывает детали создания от клиента. В будущем можно легко добавить другой формат (например, JSON или бинарный) через новую реализацию `MazeBuilder`. + +### Этап 3. Стратегии поиска пути – паттерн **Strategy** + +**Задача:** Реализовать семейство алгоритмов поиска пути от старта до выхода. + +- Создать интерфейс `PathFindingStrategy` с методом `findPath(maze, start, exit)`, возвращающим список клеток пути (от старта до выхода включительно) или пустой список, если пути нет. +- Реализовать минимум 3 стратегии: + - **BFS** (поиск в ширину) – гарантирует кратчайший путь по количеству шагов. + - **DFS** (поиск в глубину) – быстрый, но не обязательно кратчайший. + - **A**\* (с эвристикой, например, манхэттенское расстояние) – компромисс между скоростью и оптимальностью. + - (Опционально) **Дейкстра** – полезна для взвешенных лабиринтов, но в базовом варианте все шаги имеют вес 1, тогда она совпадает с BFS. + +Каждая стратегия возвращает путь. Для BFS/DFS используйте очередь/стек, для A\* – приоритетную очередь (heapq). Важно: алгоритмы не должны модифицировать сам лабиринт, только читать состояние клеток. + +Strategy позволяет легко переключать алгоритмы во время выполнения, не меняя код остальной программы. Новый алгоритм можно добавить, реализовав интерфейс. + +### Этап 4. Класс-оркестратор – **MazeSolver** (использует Strategy) + +**Задача:** Создать класс, который принимает лабиринт и стратегию, выполняет поиск и собирает статистику. + +- `MazeSolver` содержит поля `maze` и `strategy`. +- Метод `setStrategy(strategy)` для динамической смены алгоритма. +- Метод `solve()` вызывает `strategy.findPath(...)` и возвращает объект `SearchStats` (время выполнения в миллисекундах, количество посещённых клеток, длина найденного пути). +- Для замера времени используйте `time.perf_counter()` до и после вызова стратегии. + +### Этап 5. Визуализация и пошаговое управление – паттерны **Observer** и **Command** (по желанию) + +**5.1. Наблюдатель (Observer)** – обновление консольного интерфейса. + +- Создать интерфейс `Observer` с методом `update(event)`, где `event` может быть строкой или объектом с типом события (`"path_found"`, `"move"`, `"maze_loaded"`). +- Реализовать класс `ConsoleView`, который отображает лабиринт, текущее положение игрока (если реализован пошаговый режим) и найденный путь. Метод `render(maze, player_position, path)` рисует карту в консоли. +- `MazeSolver` (или отдельный контроллер) может иметь список наблюдателей и уведомлять их при изменении состояния. + +**5.2. Команда (Command)** – для пошагового перемещения игрока по найденному пути (или ручного управления). + +- Создать интерфейс `Command` с методами `execute()` и `undo()`. +- Реализовать `MoveCommand`, который принимает игрока (`Player`), направление и изменяет его позицию, сохраняя предыдущую для отмены. +- Создать класс `Player`, хранящий текущую клетку. +- Консольное меню позволяет вводить команды (W/A/S/D), выполнять `MoveCommand`, при необходимости отменять последний ход (Ctrl+Z). Это опционально, но очень наглядно демонстрирует паттерн. + +*Observer можно реализовать только для вывода сообщений о начале/конце поиска, а Command – для демонстрации undo при ручном исследовании лабиринта.* + +### Этап 6. Экспериментальная часть (аналогично заданию со структурами данных) + +**Задача:** Сравнить эффективность реализованных стратегий на лабиринтах разной сложности. + +1. **Подготовка тестовых лабиринтов:** + - Маленький (10×10) с простым путём. + - Средний (50×50) с тупиками. + - Большой (100×100) с запутанной структурой. + - «Пустой» лабиринт (без стен) – для демонстрации максимальной производительности. + - «Без выхода» – чтобы проверить обработку отсутствия пути. +2. **Замеры:** + - Для каждого лабиринта и каждой стратегии запустить `solve()` 5–10 раз, усреднить время, количество посещённых клеток, длину пути. + - Записать результаты в CSV: `лабиринт,стратегия,время_мс,посещено_клеток,длина_пути`. +3. **Анализ:** + - Построить графики для каждого лабиринта. + - Проанализировать и написать выводы по итогам (эффективность того или иного алгоритма в разных случаях). +4. **Дополнительное задание:** Реализовать взвешенные клетки (например, болото – вес 3, песок – вес 2, асфальт – вес 1) и сравнить Дейкстру с A\* на взвешенном графе. + +### Этап 7. Отчёт + +**Структура отчёта:** + +1. Описание задачи и выбранных паттернов (с диаграммой классов из Mermaid). +2. Листинги ключевых классов (можно выборочно) или ссылка на репозиторий. +3. Результаты экспериментов (таблицы, графики). +4. Анализ эффективности алгоритмов и применимости паттернов. +5. Выводы: как ООП и паттерны помогли сделать код гибким и расширяемым. Что было бы сложно изменить без них. + +## Советы + +- Для A\* самая простая эвристика: `abs(x1 - x2) + abs(y1 - y2)`. +- При поиске пути надо хранить предшественников (`parent` для каждой посещённой клетки), чтобы восстановить путь. +- Для BFS/DFS используй `deque` (очередь) и `list` (стек). +- Визуализацию в консоли можно сделать с помощью `os.system('cls' if os.name == 'nt' else 'clear')` для перерисовки. + +# API Reference + +## Базовые модели + +### *class* source.models.base.Cell(x: int, y: int, is_wall: bool = False, is_start: bool = False, is_exit: bool = False) + +Базовые классы: `object` + +Представляет одну клетку поля лабиринта. + +Каждая клетка хранит свои координаты и один из четырёх возможных +типов: стена, старт, выход или пустая клетка.

Модель лабиринта + +В первом этапе разработки необходимо создать базовые классы `Cell` и `Maze`, которые представляют карту лабиринта. Паттерны на этом этапе не применяются — только чистые классы. + +## Класс `Cell` + +Клетка — минимальная единица лабиринта. Хранит координаты и тип: стена, старт, выход или пустая. + +По условию задания клетка должна иметь флаги `isWall`, `isStart`, `isExit` и метод `isPassable()`.

Логика сброса вынесена в приватный метод `_clear_flags()`. + +### Символьное представление + +Для вывода лабиринта в консоль каждая клетка возвращает символ через `__str__`. Символы берутся из `cell_mapping` в `source/settings.py`, что позволяет менять отображение без правки классов: + +| Тип | Символ по умолчанию | +|--------|-----------------------| +| Стена | `#` | +| Старт | `S` | +| Выход | `E` | +| Пустая | | + +## Класс `Maze` + +Лабиринт хранит двумерный список клеток и предоставляет методы для работы с ними. + +По условию задания требовались методы `getCell(x, y)` и `getNeighbors(cell)`. В реализации добавлено несколько вещей сверх задания: + +### Именование методов + +Задание написано в стиле Java/pseudocode — названия методов и полей используют `camelCase` (`isWall`, `getCell`, `isPassable`). В Python принят другой стандарт именования — **PEP 8**, который предписывает `snake_case` для методов и атрибутов.

ConsoleView + MazeSolver --> Observer : notifies +``` + +## Выполнение + +### Этап 1. Модель лабиринта (без паттернов, просто классы) +**Задача:** Создать классы `Cell` и `Maze`, которые представляют карту лабиринта. +- `Cell` хранит координаты (x, y), флаги `isWall`, `isStart`, `isExit`, метод `isPassable()` (возвращает `True` для прохода, если не стена). +- `Maze` хранит двумерный массив клеток, ширину, высоту, ссылки на стартовую и выходную клетку. Методы: `getCell(x, y)`, `getNeighbors(cell)` – возвращает список соседних проходимых клеток (вверх, вниз, влево, вправо, если в пределах границ и не стена). + +**Результат:** Лабиринт можно создать вручную в коде, но загрузку пока не делаем. + +### Этап 2. Загрузка лабиринта из файла – применение паттерна **Builder** +**Задача:** Реализовать загрузку лабиринта из текстового файла, где `#` – стена, ` ` (пробел) – проход, `S` – старт, `E` – выход. +- Создать интерфейс `MazeBuilder` с методом `buildFromFile(filename)`. +- Реализовать класс `TextFileMazeBuilder`, который читает файл, парсит символы, создаёт объекты `Cell`, задаёт координаты и флаги, после чего возвращает готовый `Maze`. + +Процесс построения лабиринта сложный (парсинг, валидация, установка старта/выхода). Builder скрывает детали создания от клиента. В будущем можно легко добавить другой формат (например, JSON или бинарный) через новую реализацию `MazeBuilder`. + +### Этап 3. Стратегии поиска пути – паттерн **Strategy** +**Задача:** Реализовать семейство алгоритмов поиска пути от старта до выхода. +- Создать интерфейс `PathFindingStrategy` с методом `findPath(maze, start, exit)`, возвращающим список клеток пути (от старта до выхода включительно) или пустой список, если пути нет. +- Реализовать минимум 3 стратегии: + - **BFS** (поиск в ширину) – гарантирует кратчайший путь по количеству шагов. + - **DFS** (поиск в глубину) – быстрый, но не обязательно кратчайший. + - **A*** (с эвристикой, например, манхэттенское расстояние) – компромисс между скоростью и оптимальностью. + - (Опционально) **Дейкстра** – полезна для взвешенных лабиринтов, но в базовом варианте все шаги имеют вес 1, тогда она совпадает с BFS. + +Каждая стратегия возвращает путь. Для BFS/DFS используйте очередь/стек, для A* – приоритетную очередь (heapq). Важно: алгоритмы не должны модифицировать сам лабиринт, только читать состояние клеток. + +Strategy позволяет легко переключать алгоритмы во время выполнения, не меняя код остальной программы. Новый алгоритм можно добавить, реализовав интерфейс. + +### Этап 4. Класс-оркестратор – **MazeSolver** (использует Strategy) +**Задача:** Создать класс, который принимает лабиринт и стратегию, выполняет поиск и собирает статистику. +- `MazeSolver` содержит поля `maze` и `strategy`. +- Метод `setStrategy(strategy)` для динамической смены алгоритма. +- Метод `solve()` вызывает `strategy.findPath(...)` и возвращает объект `SearchStats` (время выполнения в миллисекундах, количество посещённых клеток, длина найденного пути). +- Для замера времени используйте `time.perf_counter()` до и после вызова стратегии. + +### Этап 5. Визуализация и пошаговое управление – паттерны **Observer** и **Command** (по желанию) +**5.1. Наблюдатель (Observer)** – обновление консольного интерфейса. +- Создать интерфейс `Observer` с методом `update(event)`, где `event` может быть строкой или объектом с типом события (`"path_found"`, `"move"`, `"maze_loaded"`). +- Реализовать класс `ConsoleView`, который отображает лабиринт, текущее положение игрока (если реализован пошаговый режим) и найденный путь. Метод `render(maze, player_position, path)` рисует карту в консоли. +- `MazeSolver` (или отдельный контроллер) может иметь список наблюдателей и уведомлять их при изменении состояния. + +**5.2. Команда (Command)** – для пошагового перемещения игрока по найденному пути (или ручного управления). +- Создать интерфейс `Command` с методами `execute()` и `undo()`. +- Реализовать `MoveCommand`, который принимает игрока (`Player`), направление и изменяет его позицию, сохраняя предыдущую для отмены. +- Создать класс `Player`, хранящий текущую клетку. +- Консольное меню позволяет вводить команды (W/A/S/D), выполнять `MoveCommand`, при необходимости отменять последний ход (Ctrl+Z). Это опционально, но очень наглядно демонстрирует паттерн. + +*Observer можно реализовать только для вывода сообщений о начале/конце поиска, а Command – для демонстрации undo при ручном исследовании лабиринта.* + +### Этап 6. Экспериментальная часть (аналогично заданию со структурами данных) +**Задача:** Сравнить эффективность реализованных стратегий на лабиринтах разной сложности. +1. **Подготовка тестовых лабиринтов:** + - Маленький (10×10) с простым путём. + - Средний (50×50) с тупиками. + - Большой (100×100) с запутанной структурой. + - «Пустой» лабиринт (без стен) – для демонстрации максимальной производительности. + - «Без выхода» – чтобы проверить обработку отсутствия пути. +2. **Замеры:** + - Для каждого лабиринта и каждой стратегии запустить `solve()` 5–10 раз, усреднить время, количество посещённых клеток, длину пути. + - Записать результаты в CSV: `лабиринт,стратегия,время_мс,посещено_клеток,длина_пути`. +3. **Анализ:** + - Построить графики для каждого лабиринта. + - Проанализировать и написать выводы по итогам (эффективность того или иного алгоритма в разных случаях). + +4. **Дополнительное задание:** Реализовать взвешенные клетки (например, болото – вес 3, песок – вес 2, асфальт – вес 1) и сравнить Дейкстру с A* на взвешенном графе. + +### Этап 7. Отчёт +**Структура отчёта:** +1. Описание задачи и выбранных паттернов (с диаграммой классов из Mermaid). +2. Листинги ключевых классов (можно выборочно) или ссылка на репозиторий. +3. Результаты экспериментов (таблицы, графики). +4. Анализ эффективности алгоритмов и применимости паттернов. +5. Выводы: как ООП и паттерны помогли сделать код гибким и расширяемым. Что было бы сложно изменить без них. + +## Советы +- Для A* самая простая эвристика: `abs(x1 - x2) + abs(y1 - y2)`. +- При поиске пути надо хранить предшественников (`parent` для каждой посещённой клетки), чтобы восстановить путь. +- Для BFS/DFS используй `deque` (очередь) и `list` (стек). +- Визуализацию в консоли можно сделать с помощью `os.system('cls' if os.name == 'nt' else 'clear')` для перерисовки. \ No newline at end of file diff --git a/skorohodovsa/task_2/practice/main.ipynb b/skorohodovsa/task_2/practice/main.ipynb new file mode 100644 index 00000000..0f496672 --- /dev/null +++

Анализ результатов + +### 4.1. Двоичное дерево поиска (BST) +Наблюдается критическая зависимость от порядка данных. +* **Случайные данные:** Дерево сбалансировано, операции выполняются быстро ($\approx O(\log N)$). Время вставки — 0.05 сек. +* **Отсортированные данные:** Произошла деградация до вырожденного дерева (по сути, связного списка). Каждая вставка проходит до самого глубокого уровня. Время вставки составило **~30 секунд**. +* **Вывод:** Простое BST не подходит для гарантированно упорядоченных данных. Для реальных систем требуется балансировка (AVL, Red-Black Trees). + +### 4.2. Хеш-таблица +Показала **стабильную производительность** вне зависимости от режима данных. +* Время вставки $\approx 0.01$ сек. +* Время поиска $\approx 0.0001$ сек (в 1000 раз быстрее поиска в списке). +* Это подтверждает теоретическую сложность $O(1)$ (в среднем). Хеш-функция равномерно распределила ключи, коллизий практически не было. + +### 4.3. Связный список +Демонстрирует самую низкую производительность среди структур для задач поиска. +* Вставка в случайном порядке занимает больше времени (10.8 сек), чем в отсортированном (6.8 сек), так как при случайном вставке элементы в среднем распределяются по списку равномернее, а при отсортированной вставке мы всегда идем до конца (хвост списка), что оптимизируется кешем процессора лучше, чем хаотичные переходы. +* Поиск занимает $\approx 0.1$ сек ($O(N)$), что значительно медленнее хеш-таблицы. + +--- + +## 5. Итоговые выводы + +1. **Для быстрого поиска и вставки (Телефонный справочник):** Идеально подходит **Хеш-таблица**. Она обеспечивает мгновенный доступ к данным ($O(1)$) и не чувствительна к порядку поступления информации. +2. **Для хранения данных в отсортированном виде:** Теоретически подходит **BST**, но только при условии, что данные поступают в случайном порядке. Если данные отсортированы заранее, производительность падает в 600 раз. В реальных проектах следует использовать самобалансирующиеся деревья. +3. **Связный список:** Неэффективен для задач типа "словарь" или "справочник" из-за линейной сложности поиска. Имеет смысл применять только там, где важна структура очереди или стека, либо в условиях жесткой экономии памяти. \ No newline at end of file diff --git a/sobininaas/Задание1/docs/data/plot.png

Анализ результатов + + +### 3.1. Вставка + +Связный список: проход по всему списку для поиска дубликата перед вставкой даёт O(n) на каждый элемент. При N = 10 000 это ≈50 млн операций сравнения — отсюда 3.6 с. + +Хеш-таблица: хеш вычисляется за O(len(name)), поиск в корзине ≈ O(1). Итог — 0.037 с независимо от порядка. + +BST на случайных данных: дерево остаётся примерно сбалансированным, высота ≈ log₂(10000) ≈ 13. Итог — 0.034 с. На отсортированных данных каждый новый элемент добавляется в правое поддерево, высота достигает N = 10 000 — полная деградация до O(n²) суммарно. Итог — 12.6 с (×373 замедление). + + +### 3.2. Поиск + +Связный список: в среднем просматривает N/2 узлов. При 110 запросах — ≈550 000 сравнений. Время ≈ 0.04 с. + +Хеш-таблица: поиск в корзине из ~10 элементов — практически мгновенно. Время ≈ 0.0003 с — в 130 раз быстрее связного списка. + +BST: случайный порядок — log(N) шагов, ≈ 0.0002 с. Отсортированный — линейный поиск O(n), ≈ 0.044 с (сравнимо со связным списком). + + +### 3.3. Удаление + +Связный список: необходим проход до удаляемого элемента — O(n). При 50 удалениях ≈ 0.02 с. + +Хеш-таблица: O(1) в среднем — ≈ 0.0003 с. + +BST: случайные данные — O(log n) ≈ 0.001 с. Отсортированные — O(n) ≈ 0.055 с. + + +### 3.4. Получение отсортированного списка + +Связный список и хеш-таблица: сбор всех N элементов + Python sort — O(n log n). Практически одинаково для обеих структур. + +BST: in-order обход уже возвращает отсортированный список — O(n), без дополнительной сортировки. При случайном вводе BST является наиболее эффективным для list_all. + + +## 4. Выводы и рекомендации + +На основании экспериментов можно дать следующие практические рекомендации: + +Частые вставки и поиск без упорядочивания → Хеш-таблица. Константное среднее время O(1) для всех операций, нечувствительность к порядку данных. Практически всегда лучший выбор для справочников, кэшей, индексов. + +Данные нужны в отсортированном порядке (range queries, итерация по алфавиту) → Сбалансированное BST (AVL, красно-чёрное дерево) или B-дерево. Простая BST допустима только при случайном порядке вставки. На отсортированных данных деградирует до O(n). + +Очень мало элементов или требуется простота реализации → Связный список. При N < 100 разница в скорости незначительна, а код минимальный. + +BST (сбалансированный) vs Хеш-таблица: если нужно только find/insert/delete — хеш-таблица быстрее. Если нужны min/max, range-запросы, сортировка — BST предпочтительнее. + +Итог: для реального телефонного справочника с операциями insert/find/delete оптимальна хеш-таблица. Если требуется регулярный вывод списка по алфавиту — BST (сбалансированное). Связный список применим только как учебная модель или для очень маленьких N. diff --git a/soninrv/docs/report2.md b/soninrv/docs/report2.md new file mode 100644 index 00000000..d626e8e1 --- /dev/null +++ b/soninrv/docs/report2.md @@ -0,0 +1,105 @@ +# Отчёт по лабораторной работе «Поиск выхода из лабиринта» + +## 1.

DFS + +Самый быстрый алгоритм по времени: на лабиринте 100×100 — 5.1 мс против 11.4 мс у BFS. Посещает вдвое меньше клеток (2161 против 4783), так как уходит глубоко в одном направлении. Однако на пустом лабиринте DFS даёт путь в 7 раз длиннее оптимального (379 против 55) — алгоритм уходит в угол и обходит весь лабиринт по периметру. Оптимальная длина пути при этом совпадает с BFS только в лабиринтах-лабиринтах (50×50 и 100×100), где единственный путь — сам. + +### 4.3. A\* + +На невзвешенных лабиринтах находит тот же кратчайший путь, что BFS, но исследует на 20–30% меньше клеток благодаря манхэттенской эвристике (на 50×50: 357 против 493). Однако на большом лабиринте 100×100 оказывается медленнее BFS (18 мс против 11 мс) из-за накладных расходов на `heapq`. На взвешенном лабиринте A\* корректно учитывает стоимость клеток, в отличие от BFS. + +### 4.4. Dijkstra + +На невзвешенных лабиринтах полностью совпадает с BFS по посещённым клеткам и длине пути, но медленнее из-за `heapq` вместо `deque`. На взвешенном лабиринте 40×40 корректно минимизирует суммарный вес пути. Практически вытесняется A\* везде, где цель заранее известна. + +### 4.5. Лабиринт «без выхода» + +Все алгоритмы обходят все 162 доступные клетки левой секции и возвращают пустой путь. Реализация корректно обрабатывает этот случай через событие `no_path` для Observer. A\* и Dijkstra работают медленнее (0.7 мс против 0.37 мс у BFS/DFS) из-за накладных расходов `heapq` при полном обходе без нахождения цели. + +## 5. Выводы и рекомендации + +На основе полученных результатов можно сформулировать следующие рекомендации: + +- **Кратчайший путь в невзвешенном лабиринте → BFS.** Гарантированный результат, простая реализация на `deque`, линейное масштабирование. + +- **Максимальная скорость, длина пути не критична → DFS.** В 2 раза быстрее BFS на больших лабиринтах, посещает вдвое меньше клеток. Не использовать на открытых пространствах — путь может быть многократно длиннее оптимального. + +- **Взвешенный граф, цель известна → A\*.** Направленный поиск + учёт весов. На небольших и средних лабиринтах быстрее и экономнее BFS. На очень больших (100×100+) накладные расходы `heapq` могут перевесить выигрыш от эвристики. + +- **Взвешенный граф, нужны все кратчайшие расстояния → Dijkstra.** Оптимален без целевой точки. С целевой точкой предпочтительнее A\*. + +**Итог:** для навигации в лабиринте с одним выходом оптимален BFS (гарантия) или DFS (скорость). A\* предпочтителен при взвешенных клетках. Паттерн Strategy позволяет переключать алгоритмы без изменения остального кода — `solver.set_strategy(AStarStrategy())`. + + diff --git a/sorokinfi/427.md b/sorokinfi/427.md new file mode 100644 index 00000000..e69de29b diff --git a/src/bst.py b/src/bst.py new file mode 100644 index 00000000..04ba1d39 --- /dev/null +++ b/src/bst.py @@ -0,0 +1,88 @@ +# bst.py +# Двоичное дерево поиска по имени + +def create_node(name, phone): + """Создаёт узел дерева.""" + return { + 'name': name, + 'phone': phone, + 'left': None, + 'right': None + } + +def bst_insert(root, name, phone): + """ + Рекурсивно вставляет или обновляет запись. + Возвращает корень (может измениться при первой вставке). + """ + if root is None: + return create_node(name, phone) + + if name < root['name']: + root['left'] = bst_insert(root['left'], name, phone) + elif name > root['name']: + root['right'] = bst_insert(root['right'], name, phone) + else: #

Поэтому хеш-таблица ни на одном из этапов не сравнивает данные, следовательно их порядок не влияет на скорость. + +### Почему связный список всегда медленен при поиске. +Операция поиска в связном списке имеет линейную сложность $O(n)$ не зависимо от порядка данных, что можно видеть на графике (см. рис. 2). Для бинарного дерева поиска эта сложность в лучшем случае $O(\log(N))$, а в худшем $O(N)$. Для хеш-таблицы сложность вставки $O(1)$, с хорошей хеш-функцией и низким заполнением. + +### Как удаление работает в каждой структуре. +#### Связный список +Находим элемент перед удаляем элементом, и заменяем его поле `next` на `next.next`, то есть теперь он указывает на элемент, который идёт после удаляемого элемента: +``` Go +current := ll.head + +for current.next != nil { + if current.next.data.Name == targetName { + current.next = current.next.next + return true + } + current = current.next +} +``` + +#### Бинарное дерево поиска +После того, как мы нашли узел, который необходимо удалить, у нас возможны три случая. + +Случай 1: У удаляемого узла нет правого ребенка. +В этом случае мы просто перемещаем левого ребенка (3) на место удаляемого узла(5).

Анализ эффективности алгоритмов и применимости паттернов + +### Алгоритмы + +**BFS** гарантирует кратчайший путь по числу шагов. Расширяет узлы слой за слоем во всех направлениях, поэтому посещает наибольшее число клеток. На практике это надёжный выбор когда нужен точно кратчайший маршрут. + +**DFS** посещает меньше клеток и выполняется быстрее - на large лабиринте в 1.8 раза быстрее BFS. Однако путь может быть далеко не кратчайшим. На пустом лабиринте DFS нашёл путь длиной 451 шаг, тогда как BFS и A* - 67. Это связано с тем, что DFS уходит в первое попавшееся направление и возвращается только в тупике. + +**A*** использует манхэттенскую эвристику h = |x1-x2| + |y1-y2| и должен в теории посещать меньше клеток чем BFS. На лабиринтах, сгенерированных алгоритмом recursive backtracker, выигрыш небольшой (примерно 5%). Причина: backtracker строит дерево - между любыми двумя клетками ровно один путь, тупиков нет, эвристика не помогает их обходить. На лабиринтах с циклами A* посещает заметно меньше клеток. Накладные расходы на работу с heap и closed-set делают A* медленнее по времени, чем DFS. + +На пустом лабиринте (без стен) A* ведёт себя как BFS. Математически: f(x,y) = g + h = (x-1+y-1) + (W-x+H-y) = const для всех клеток. Все узлы неразличимы по приоритету. + +На лабиринте без выхода все три алгоритма посещают одинаковое число клеток и корректно возвращают пустой путь. + +### Паттерны + +**Builder** оказался полезным при добавлении нового типа лабиринта (взвешенного, с символами s и m). Изменения были внесены только в `TextFileMazeBuilder`, клиентский код не менялся. + +**Strategy** позволил в одном цикле запустить все три алгоритма через `solver.set_strategy(strategy)`. Без паттерна пришлось бы либо дублировать код запуска для каждого алгоритма, либо писать условные ветки. + +**Observer** полезен при расширении: чтобы добавить вывод в лог или консоль, достаточно написать новый Observer и подписать его на solver, не меняя `MazeSolver`. + +--- + +## 5. Выводы + +ООП и паттерны позволили сделать код гибким в нескольких направлениях. + +Добавление нового алгоритма поиска сводится к написанию одного класса, реализующего `find_path()`. Без Strategy пришлось бы добавлять ветку в `solve()` и во все места, где запускается поиск. + +Добавление нового формата лабиринта - только новый класс Builder. Без паттерна логика парсинга была бы перемешана с логикой работы программы. + +Добавление нового способа отображения (GUI, запись в файл) - только новый Observer. Без него MazeSolver пришлось бы напрямую вызывать функции отображения, что создало бы зависимость от конкретной реализации. + +Без применения паттернов код решал бы задачу, но любое изменение требовало бы правки в нескольких местах сразу. С паттернами каждый класс отвечает за одну задачу и не знает о деталях реализации соседних классов. diff --git a/svetlakovkyu/02/main.py b/svetlakovkyu/02/main.py new file mode 100644 index 00000000..8a358bd2 --- /dev/null +++ b/svetlakovkyu/02/main.py @@ -0,0 +1,165 @@ +import csv +import os +import sys + +sys.path.insert(0, os.path.join(os.path.dirname(__file__), "codes")) + +from maze import TextFileMazeBuilder, MazeSolver, BFSStrategy, DFSStrategy, AStarStrategy +from maze_generator import generate_all + +try: + import matplotlib.pyplot as plt + import matplotlib + matplotlib.use("Agg") + HAS_PLT = True +except ImportError: + HAS_PLT = False + +BASE_DIR = os.path.dirname(__file__) +MAZES_DIR = os.path.join(BASE_DIR, "mazes") +RESULTS_DIR = os.path.join(BASE_DIR, "results") +RUNS = 7 + +MAZE_FILES = [ + ("small", "small.txt"), + ("medium", "medium.txt"), + ("large", "large.txt"), + ("empty", "empty.txt"), + ("no_exit", "no_exit.txt"), +] + + +def run(): + os.makedirs(RESULTS_DIR, exist_ok=True) + + if not os.path.exists(MAZES_DIR) or not os.listdir(MAZES_DIR): + generate_all(MAZES_DIR) + + strategies = [BFSStrategy(), DFSStrategy(), AStarStrategy()] + builder = TextFileMazeBuilder() + all_results = [] + + for label, filename in MAZE_FILES: + path = os.path.join(MAZES_DIR, filename) + if not os.path.exists(path): + continue + + maze = builder.build_from_file(path) + print(f"\nMaze: {label} ({maze.width}x{maze.height})") + + solver = MazeSolver(maze, strategies[0]) + + for strategy in strategies: + solver.set_strategy(strategy) + times, visited_list, lengths = [], [], [] + + for _ in range(RUNS): + stats = solver.solve() + times.append(stats.time_ms) + visited_list.append(stats.visited) + lengths.append(stats.path_length) + + avg_time = sum(times) / RUNS + avg_visited = sum(visited_list) / RUNS + avg_len = sum(lengths) / RUNS + + found = f"length={avg_len:.0f}" if avg_len > 0 else "not found" + print(f" {strategy.name:<6} time={avg_time:.4f} ms visited={avg_visited:.0f} {found}") + + all_results.append({ + "maze": label, + "strategy": strategy.name, + "time_ms": round(avg_time, 4), + "visited_cells": round(avg_visited, 1), + "path_length": round(avg_len, 1), + }) + + save_csv(all_results) + save_plots(all_results) + show_sample() + print("\nDone.

Анализ результатов + +### 4.1 Влияние порядка данных на BST: деградация до O(n) + +При вставке случайных данных BST ведёт себя как сбалансированное дерево: каждый новый ключ с равной вероятностью уходит влево или вправо, глубина дерева составляет ~log₂(10000) ≈ 13. Операция вставки 10 000 записей заняла 0.025 сек. + +При вставке отсортированных данных каждый новый ключ оказывается больше предыдущего и всегда уходит вправо. Дерево вырождается в линейный список глубиной 10 000. Каждая следующая вставка проходит на один шаг дальше, итоговая сложность становится O(1 + 2 + ... + n) = O(n²). Именно поэтому вставка отсортированных данных заняла 13.16 сек - более чем в 500 раз медленнее случайных. + +Это фундаментальный недостаток, реализованного BST. + +--- + +### 4.2 Нечувствительность хеш-таблицы к порядку данных + +Хеш-таблица вычисляет позицию элемента через `hash(name) % len(buckets)`. Функция `hash()` в Python зависит только от значения ключа, но никак не от порядка вставки. Независимо от того, отсортированы данные или перемешаны, каждый ключ попадает в тот же бакет с той же скоростью. + +Это подтверждается полученными результатами: время вставки для случайных данных - 0.0281 сек, для отсортированных - 0.0286 сек, что практически одинаково. + +В графике для поиска и удаления, моожно заметить примено такой же результат - время работы программы для отсортированных и не для неотсортированных данных одинаково. + +--- + +### 4.3 Медленный поиск в связном списке + +Связный список не имеет структуры, позволяющей перейти к нужному элементу. При поиске приходится последовательно проходить узел за узлом от головы до нужного элемента - это линейный поиск O(n). + +При N = 10 000 и 110 запросах среднее время поиска составило 0.03 сек, в ~150 раз медленнее поиска в BST и в ~75 раз медленнее поиска в HT на случайных данных. + +Порядок данных на LL практически не влияет: в любом случае нужно проходить примерно половину списка для найденных и весь список для несуществующих записей. + +--- + +### 4.4 Удаление в каждой структуре + +Связный список: удаление требует сначала найти удаляемый элемент - O(n). Затем достаточно переключить одну ссылку у предшественника. Итог: O(n) за счёт поиска. При 50 удалениях время составило ~0.02 сек. + +Хеш-таблица: вычисляем бакет за O(1), затем удаляем элемент из короткой цепочки. Итог: O(1) амортизированно. При 50 удалениях время составило 0.00003 сек для случайных и 0.00004 для отсортированых данных, что значительно быстрее связного списка, но медленее BST(для неотсортированных данных). + +BST (случайные данные): находим узел за O(log n). Если у него два потомка - находим минимум правого поддерева, копируем его значение и рекурсивно удаляем его. Итог: O(log n). При 50 удалениях время составило 0.00012 сек. + +BST (отсортированные данные): дерево вырождено в список, глубина O(n). Каждое удаление - O(n), 50 удалений - 0.060 сек, что медленнее даже связного списка. + +--- + +## 5. Выводы + +Из результатов эксперимента, можно сделать вывод, что нет универсальной структуры данных, и под конкретную задачу надо выбирать определенную. + + +Хеш-таблица - лучший выбор, если нужны быстрые вставка, поиск и удаление и порядок хранения данных не важен. Идеальна для кешей, словарей, телефонных справочников, где операции выполняются в O(1). Не подходит для задач, требующих обхода данных в отсортированном порядке. + +BST - лучший выбор, когда важен порядок данных: обход дерева in-order даёт отсортированную последовательность за O(n), можно быстро найти минимум/максимум или диапазон ключей.

Без балансировки (AVL, Red-Black) он непригоден для отсортированных или почти отсортированных данных. + +### 4.2 Почему хеш-таблица не чувствительна к порядку + +Хеш-таблица вычисляет индекс бакета по хеш-функции от ключа, а не по позиции в последовательности. Порядок вставки не влияет на распределение по бакетам: + +- **Случайный:** 0.025 сек +- **Отсортированный:** 0.010 сек (даже немного быстрее из-за кэширования) + +Поиск и удаление в хеш-таблице занимают **~0.0002 сек** — практически константное время O(1). + +### 4.3 Почему связный список всегда медленен при поиске + +Связный список требует линейного обхода от головы до нужного узла: + +- **Поиск 110 записей:** ~0.024 сек (в среднем ~0.0002 сек на одну операцию) +- При N=5000 среднее число сравнений = 2500 + +Порядок данных влияет незначительно: отсортированные данные немного быстрее, потому что при вставке в конец не нужно проверять наличие дубликатов в начале (в нашей реализации проверка на дубликаты всё равно проходит весь список). + +### 4.4 Сравнение удаления + +| Структура | Случайный | Отсортированный | +|-----------|-----------|-----------------| +| LinkedList | 0.016 сек | 0.014 сек | +| HashTable | 0.0001 сек | 0.0001 сек | +| BST | 0.0002 сек | 0.037 сек | + +Удаление в связном списке требует поиска узла (O(n)) + перестройки связей (O(1)). +Удаление в хеш-таблице — поиск в бакете (O(1) в среднем). +Удаление в BST — поиск + перестройка дерева. При вырожденном дереве — O(n). + +--- + +## 5. Выводы и рекомендации + +### Какую структуру выбрать? + +| Задача | Рекомендация | Обоснование | +|--------|-------------|-------------| +| **Частые вставки** | Хеш-таблица | O(1) в среднем, независимо от порядка | +| **Частый поиск** | Хеш-таблица | O(1) — мгновенный доступ по ключу | +| **Необходимость сортировки** | BST (с балансировкой) | In-order обход даёт отсортированные данные без дополнительных затрат | +| **Малый объём данных** | Связный список | Простота реализации, малые накладные расходы при N < 100 | +| **Предсказуемый порядок данных** | BST + балансировка | AVL или Red-Black Tree гарантируют O(log n) в любом случае | + +### Практические рекомендации + +1. **Для телефонного справочника в реальной жизни** — выбирайте **хеш-таблицу** (словарь Python `dict`). Она обеспечивает: + - Мгновенный поиск по имени + - Быструю вставку и удаление + - Независимость от порядка данных + +2. **Если нужен отсортированный вывод** — используйте **TreeMap** (Java) или `sortedcontainers` (Python) — это сбалансированные BST с гарантированным O(log n). + +3. **Связный список** имеет право на жизнь только когда: + - Нужна частая вставка/удаление в середину + - Данные уже упорядочены + - Объём данных невелик + +### Итог эксперимента + +| Структура | Случайный (вставка) | Отсортированный (вставка) | Устойчивость |
