+# Отчёт: Задание 2 — Поиск выхода из лабиринта 
+
+## 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
+
+## Выбранные паттерны и их обоснование
+
+### Builder
+
+Для загрузки лабиринта из файла был использован паттерн Builder.
+Создан интерфейс:
+class MazeBuilder():
+и его реализация:
+class TextFileMazeBuilder(MazeBuilder):
+Преимущества использования Builder:
+пользоватеь не знает деталей создания лабиринта;
+можно добавить новые форматы (JSON, XML, бинарный);
+код загрузки изолирован от остальной программы.
+
+### Strategy
+
+Для алгоритмов поиска пути использован паттерн Strategy
+Создан общий интерфейс:
+class PathFindingStrategy():
+Реализованы стратегии:
+BFSStrategy;
+DFSStrategy;
+AStrategy;
+Каждая стратегия реализует собственный алгоритм поиска пути по правилам.
+Преимущества паттерна:
+алгоритмы можно менять во время выполнения;
+код MazeSolver не зависит от конкретного алгоритма;
+новые алгоритмы можно добавлять без изменения существующего кода.
+
+### Observer
+
+Для уведомления интерфейса о событиях использован паттерн Observer
+Создан интерфейс:
+class Observer():
+и реализация:
+class ConsoleView(Observer):
+MazeSolver хранит список наблюдателей и уведомляет их о событиях:
+начало поиска;
+окончание поиска;
+перемещение игрока.
+Преимущества:
+логика интерфейса отделена от логики поиска;
+можно легко добавить графический интерфейс;
+
+### Command
+
+Для пошагового перемещения игрока использован паттерн Command.
+Создан интерфейс:
+class Command():
+и реализация:
+class MoveCommand(Command):
+Каждая команда умеет:
+execute() — выполнить действие;
+undo() — отменить действие
+Преимущества:
+поддержка undo;
+возможность расширения системы команд
+
+## Листинги ключевых классов
+
+### Паттерн Strategy

+    def findPath(self, maze, start, exit):

+                    queue.append(neighbor)
+        
+        return []

+                    g_score[neighbor] = tentative_g
+                    f_score = tentative_g + self._heuristic(neighbor, exit)
+                    heapq.heappush(open_set, (f_score, neighbor))
+        
+        return []
+

+        new_y = self.player.currentCell.y + self.dy
+        new_cell = self.maze.getCell(new_x, new_y)
+        if new_cell and new_cell.isPassable():
+            self.player.moveTo(new_cell)
+            self.executed = True

+
+## Анализ эффективности алгоритмов
+
+В ходе экспериментов были получены следующие результаты.
+
+### BFS
+Преимущества:
+всегда находит кратчайший путь;
+простая реализация.
+Недостатки:
+посещает большое количество клеток;
+требует много памяти.
+Выходит, что наиболее эффективен в небольших невзвешенных лабиринтах.
+
+### DFS
+Преимущества:
+простая реализация;
+самым быстрым находит произвольный путь.
+Недостатки:
+не гарантирует кратчайший путь;
+может уходить в тупики.
+Подходит для быстрого поиска любого решения.
+
+### A
+Преимущества:
+высокая скорость;
+посещает меньше клеток;
+Недостатки:
+требует выбора хорошей эвристики.
+Показал хорошие результаты на больших лабиринтах.
+
+## Анализ применимости паттернов
+
+### Builder
+Без Builder код загрузки лабиринта был бы жёстко связан с классом Maze, а добавление нового формата потребовало бы изменения существующего кода.
+Strategy
+Без Strategy пришлось бы:
+хранить все алгоритмы внутри одного класса;
+использовать большое количество условных операторов;
+изменять код MazeSolver при добавлении новых алгоритмов
+Strategy помог полностью отделить алгоритмы друг от друга.
+
+### Observer
+Без Observer логика интерфейса смешивалась бы с логикой поиска.
+Это усложнило бы:
+добавление GUI;
+логирование;
+визуализацию.
+
+### Command
+Без Command было бы сложно реализовать:
+undo;
+историю действий;
+расширяемую систему управления.
+
+## Выводы
+
+### В проекте были успешно реализованы:
+загрузка лабиринта из файла;
+несколько алгоритмов поиска пути;
+визуализация;
+система наблюдателей;
+система команд;
+экспериментальное сравнение алгоритмов.
+
+### Использование паттернов GoF позволило:
+сделать архитектуру гибкой;
+уменьшить связанность компонентов;
+упростить расширение программы;
+облегчить сопровождение кода.
