My attempt at solving the 3x3 Rubik's cube (by programming the computer to do it for me). Note: in the evaluation function at 22:32 I mention that it falls back to the 'Greedy' evaluator shown previously. However, I forgot that I had made a small change to that function, which is to give a bonus to correctly oriented corners. Sorry for the oversight!
