[FRIAM] Watching a Moose solve a Maze Re: solving mazes

[Stephen Guerin]

Late September 2009, a young M0ose (Cody Smith) walked into the Santa Fe
Complex.

He approached me and said he heard about the place and wanted to help
contribute. He showed me some of his computational sketches on his laptop.

One that caught my eye was his Javascript breadth-first maze solver:
  http://www.m0ose.com/oldpage/breadth_first_with_graph.html

and a genetic algorithm solver:
http://www.m0ose.com/oldpage/maze_evolution8.html

His repository has grown over the decade: http://m0ose.com

Note his maze generator here:

And his WebGL Doom maze walker from Ed Angel's WebGL class at SF_X:
