Several programs for working with Rubik's cubes.
There are several programs for working with Rubik's cubes, by three different people. Look inside the directories under /src to see specific info and licensing. In summary the three contributers are:
Michael Reid (GPL) http://www.math.ucf.edu/~reid/Rubik/optimal_solver.html optimal - uses many pre-computed tables to find an optimal solution to the 3x3x3 Rubik's cube
Dik T. Winter (MIT License) cube - uses Kociemba's algorithm to iteratively find a short solution to the 3x3x3 Rubik's cube size222 - solves a 2x2x2 Rubik's cube
Eric Dietz (GPL) http://www.wrongway.org/?rubiksource cu2 - A fast, non-optimal 2x2x2 solver cubex - A fast, non-optimal 3x3x3 solver mcube - A fast, non-optimal 4x4x4 solver.
