It would be tricky indeed to implement Japanese scoring with Monte Carlo programs.
Monte Carlo programs are very strong and thus they are not naive about what the situation is. But I view them as "relativistic players" - whether a group is dead or alive depends on your point of view! A group is dead if it needs to be dead to win. This makes it a difficult fit for scoring dead groups. A monte carlo go program might even play a move that makes it possible to win your dead group back if it's not relevant to it's winning chances. So dead group analysis must be done by external methods in my opinion. Also, Japanese scoring is problematic because it gives meaning to moves which should be considered meaningless. Monte Carlo only cares about meaningful moves - moves which increase the winning chances. Some of the moves that Monte Carlo considers worthless are considered to be negative worth in Japanese scoring. When a monte carlo program thinks the game is dead won or lost, you can stop playing - but you can't necessarily get a correct bean count of the position. So I don't think Japanese scoring is compatible with Monte Carlo methods - although with some cleverness I'm sure it's possible to impose it. It occurred to me that you could build your play-outs to use Japanese counting. I'm sure this would weaken the program considerably however. Japanese scoring would impose a lot of "noise" on the positions. - Don [EMAIL PROTECTED] wrote: > It takes some tricky analysis to work out the Japanese score, due to > uncertainty about life/death; likewise it's not easy for a program to > recognize when moving is no longer to its advantage. > > How about bringing in a Monte Carlo routine after both players have > passed?--as a scoring referree, set to fill up the board (but avoiding > eye-filling and self-atari except in ko situations) until all legal moves > are played, then either a) Do a Chinese score or b) use information re > which groups are still on the board & where the final borders ended up to > score the actual ending position? > > Forrest Curo > San Diego > > > ----------------------------------------- > This email was sent using AIS WebMail. > http://www.americanis.net/ > > > _______________________________________________ > computer-go mailing list > computer-go@computer-go.org > http://www.computer-go.org/mailman/listinfo/computer-go/ > > _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
