### Solving mazes with programming

Everyone knows what mazes/labyrinths are! And plenty of us find it amusing to try and solve one! Take the image above as an example... Can you find a path from the top left opening to the bottom right opening? There exists at least one!

I wrote a program in Python (making use of pygame and Pillow) to solve any maze given. I did this project several years ago, after learning about Dijkstra's algorithm. I read about the algorithm and decided to implement it, to get a feel for it. I realized that I could apply it to a maze in a picture, if I took each pixel of the image to be a vertex in the graph where I'd apply the method.

I wanted to make my program fairly general, in terms of the mazes that could be given, and so I dwelled with a problem: how to tell if two adjacent pixels should be connected in the graph or not. I knew I only wanted to connect pixels that referred to the path, and not to the walls, so my idea was simple: I supposed that a picture of a maze would have mainly…
