You play until neither player wishes to make a move. The players are willing to move on any point that is not self-atari, and they are willing to make self-atari plays if capture would result in a Nakade (http://senseis.xmp.net/?Nakade)
This correctly plays seki.

When I asked this question I had to search a lot of papers on MCTS which mentioned "terminal states" before finding one which defined them. Let me see if I can find the actual paper, but they defined it as a position where there are no more legal moves. You're right though, that ignores sekis, which makes me think I'm remembering wrong.

[Insert appropriate praises here.] I am trying to understand the part where you use reinforcement learning to improve upon the CNN trained by imitating humans. One thing that is not explained is how to determine that a game is over, particularly when a player is simply a CNN that has a probability distribution as its output. Do you play until every point is either a suicide or looks like an eye? Do you do anything to make sure you don't play in a seki? I am sure you are a busy man these days, so please answer only when you have time. Thanks! Álvaro.

AlphaGo beat the European champion Fan Hui by 5 games to 0. We hope you enjoy our paper, published in Nature today. The paper and all the games can be found here: http://www.deepmind.com/alpha-go.html AlphaGo will be competing in a match against Lee Sedol in Seoul, this March, to see whether we finally have a Go program that is stronger than any human! Aja PS I am very busy preparing AlphaGo for the match, so apologies in advance if I cannot respond to all questions about AlphaGo. _______________________________________________ Computer-go mailing list [email protected] <mailto:[email protected]> http://computer-go.org/mailman/listinfo/computer-go _______________________________________________ Computer-go mailing list [email protected] <mailto:[email protected]> http://computer-go.org/mailman/listinfo/computer-go
