HeadingNorth Posted August 11, 2010 Share Posted August 11, 2010 At the risk of upsetting religious types, the theoretical "perfect algorithm" for solving Rubik's cube - that is, the algorithm that would always solve it, no matter what the starting position, in the minimum possible number of moves - has long been known as "God's Algorithm" ... reflecting the fact that God, if he was interested in the Rubik's Cube at all, would always solve it perfectly. "God's Number," by the same token, is the largest number of moves that is ever absolutely necessary to solve the Cube. It is now claimed that, no matter what the starting position of the Cube, it is possible to solve it in twenty moves or less. http://www.bbc.co.uk/news/technology-10929159 Actually writing down a formula that you could follow in order to achieve this, is probably still a long way off.

They may go on to investigate other puzzles of different sizes. This is certainly not something I would dedicate thirty years of my life to figuring out, although I find the results interesting.

HeadingNorth Posted August 11, 2010 Author Share Posted August 11, 2010 Why would it upset "religious types"? Certain religious types - a small minority in any religion, it must be said - get offended whenever the word "God" is used in any context outside of their own religion. Some would be offended at the very notion that God might play the Rubik's Cube. It would be a silly thing over which to take offence, but I dare say that some people still would do so.

An interesting theoretical question, and I don't know the answer. I'm not sure that anything larger than a 3x3 cube can be physically built. The inner squares would not be able to move independently, would they? Link to comment Share on other sites More sharing options...
