Something like this: I believe score is appropriate when the early/mid game not when the score is extreme. It seems correct to sacrifice a lot of expected score for a better chance of getting 0.5 win in the endgame. But it seems wrong in the early game when the "noise" of the rest of the game might take away the 0.5 win even if you get it (and you are sacrificing a lot of expected score). > > extremeness = 2 * abs(WinRate - 0.5) > Eval = (1 - extremeness) * WinRate + extremeness * ExpectedScore; > > I think ExpectedScore would need to be in the range 0 to 1, just like WinRate. > _______________________________________________ > Computer-go mailing list > [email protected] > http://dvandva.org/cgi-bin/mailman/listinfo/computer-go > -- Łukasz _______________________________________________ Computer-go mailing list [email protected] http://dvandva.org/cgi-bin/mailman/listinfo/computer-go
