Chee, both, Kingvsrow and Cake, are doing better than Chinook, either GAYP or 3-moves.Chee Xiong wrote:If Kingsrow and Cake are both very close to playing perfect checkers, maybe not on the level of today's Chinook but close enough.
They have different moves, because these are two different programs written by two different authors and having a different engine and searching algorythm.
If you have two strong players - they make different moves, same for programs. In each position often enough there are 1-2-3 moves with identical or close strength and programs may prefer either way.
Neither program yet is close to "solve" the game at high level (make the best move). Chinook solved GAYP at low level (don't make a losing move) but this is not the same. In addition - nobody knows what does it mean - "best move". There are different opinion on this matter this is another reason why Kingsrow and Cake have different moves. It is vert possible that both, Kingsrow and Cake choice, are best at some point.
