[computer-go] Monte-Carlo and Japanese rules

2008-11-09 Thread Ingo Althöfer
Hi Remi, thx for your hints. I am playing 9x9 interactively, with taking advice from Leela and ManyFaces. The basic procedure is to run both in a giving position - and making the final choice amongst their move proposals with my human brain. So I have some better potential for corrections then in

Although what Don writes is all correct, I understood the question to be rather different. It's not a matter of being able to determine the right score at the end or the right way to play, it's a matter of determining the right score after each playout. For performance reasons MC programs w

IIRC under official Japanese rules at the end of the game all groups with liberties shared between opposing colours are by definition in seki. Therefore eventually (before counting) all dame have to be filled. Further, playing dame points is almost equally bad under Chinese rules as it is under Ja
