LinkedListMazeSolver 1.0.0

This class is designed to solve a linked-list dictonary maze using the A* or Breadth-First algorithms. It takes a maze as input, represented as a dictionary where each key represents a room and the exits value is another dictionary that contains the exits of the room.

Linked-List Maze Solver

This python class provides an A* algorithm to solve linked list, represented as a dictonary, mazes. It can be used to find the shortest path between a start and end point in a maze.

The LinkedListMazeSolver class is optimized for readability and performance. It has been designed to work with mazes that contain linked list representations with no x,y,z coordinates.

Usage

from LinkedListMazeSolver import AStarMazeSolver, BFSMazeSolver

maze = {
    "A": {"exit": {"n": "B", "e": "D", "w": "C", "ne": "G", "nw": "F"}},
    "B": {"exit": {"s": "A"}},
    "C": {"exit": {"e": "A"}},
    "D": {"exit": {"w": "A", "ne": "G", "se": "H", "u": "K"}},
    "E": {"exit": {"n": "F", "e": "H", "ne": "I"}},
    "F": {"exit": {"s": "E", "ne": "G", "se": "C"}},
    "G": {"exit": {"s": "A", "nw": "F", "sw": "E"}},
    "H": {"exit": {"w": "D", "n": "I", "nw": "E"}},
    "I": {"exit": {"s": "H", "sw": "D"}},
    "J": {"exit": {"n": "K", "e": "L"}},
    "K": {"exit": {"s": "J", "d": "D"}},
    "L": {"exit": {"w": "J", "e": "M"}},
    "M": {"exit": {"w": "L"}},
}

solver = AStarMazeSolver(maze, "A", "M")
result = solver.solve()
print(result)
solver = BFSMazeSolver(maze, "A", "M")
result = solver.solve()
print(result)

Output

e u s e e
e u s e e

Supported Maze Directions

This implementation was designed with a maze containing the following directions:

n, s, e, w, ne, nw, se, sw, u, d

However, you may define your own directions in your sample data.

Customization

If you need to customize the behavior of the BidirectionalAStarMazeSolver class, you can do so by subclassing the class and overriding its methods.

For example, if you want to use a different heuristic function, you can override the heuristic method:

class CustomMazeSolver(AStarMazeSolver):
    def __heuristic__(self, curr, end, maze):
        # Custom heuristic function
        pass
