It just so happens in the June edition (#190) of PCPlus magazine (www.pcplus.co.uk) there wasa whole section on the rubik's cube and how to write a program for it, in fact it's suppose to continue in July's edition too (#191). Okay so it's a PC mag in the UK, but I know that you if you really wanted to get it sent to anywhere in the world. Or just wait 6-7 months and download it from the net.
Yes. x = problem (in this case a cubical puzzle) y = an appropriate tool z = your hands a = force applied b = reversed force applied c = lack of patience with long winded pointless solution n = solution Ok, here we go: (yz) + a + c > x (z + b)c = n I call this the "Alexander Equation".
I saw this dude on TV that had 4 I think of these cubes, rotated in a random way. He looked at them for a few minutes then put on a blindfold and solved all of them. Most impressive
