MoHex 2.0: a pattern-based MCTS Hex player
Full Text: 2013-CG-Mohex2.0.pdfIn recent years the Monte Carlo tree search revolution has spread from computer Go to many areas, including computer Hex. MCTS Hex players now outperform traditional knowledge-based alpha-beta search players, and the reigning Computer Olympiad Hex gold medallist is the MCTS player MoHex. In this paper we show how to strengthen MoHex, and observe that — as in computer Go — using learned patterns in priors and replacing a hand-crafted simulation policy with a softmax policy that uses learned patterns can significantly increase playing strength. The result is MoHex 2.0, about 250 Elo stronger than MoHex on the 11×11 board, and 300 Elo stronger on 13×13.
