Re: [computer-go] MoGo

teh epsilons summed up, but in the endgame, when all moves lead to a certain victory, the program prefers a win by a larger margin. My Halgo does that (in a otherwise regular MC), and the feel of the endgame is clearly more reasonable than without. -H -- Heikki Levanto In Murphy We Turst
