Labyrinther - solving mazes with GA in Python

What and why?

This is a project developed for an undergraduate course "Introduction to Artificial Intelligence" in Wrocław University of Science and Technology.

The task given to us was to make a program that would solve mazes using a genetic algorithm, representing the path itself as a sequence of bits (2 bits is enough to encode top/bottom/left/right).

This application serves as a Flask server that gives you access to a console (http://127.0.0.1:5000/) allowing you to run different simulations. While you have to provide a maze that the algorithm will solve, there are some example mazes (2x2, 3x3, 5x5 and 10x10) in the project itself, in the directory example_labyrinths. If you want to make your own maze, please look at the format that the mazes have in example_labyrinths or edit them to your liking. You can also generate mazes by using the labyrith module.

Setting up the simulation

Once simulated, you can view the performance of the resulting algorithm as well as the steps that it took (http://127.0.0.1:5000/<simulation-id>, ex: http://127.0.0.1:5000/47)

In the chart above, orange circle marks the start of the labyrinth, gold square - its end, red triangle means marks a point where one iteration of the algorithm died, and the purple X - the final point of the final iteration of the algorithm.
