Hi Hideki, Your results look similar to those of Mogo as reported in their icml paper. When you ran this experiment, did you use anything like FPU or progressive widening, or did you use Levente's original design which always selects unvisited moves first? Regards, Erik On Wed, Feb 6, 2008 at 3

I know that other people have mentioned this sort of thing already, but the result of level 8 being better than level 10 matches my own experience with slightly older versions of gnugo. As I recall, 8 was the best, 9 a little worse, and 10 worse again. Increasing the level seems to improve play a

Just curious if anyone knows if this is possible. cgosView has a mac (universal) binary that I'd expect to be runnable. I just don't know if the iPhone is restricted or has any other special requirements. I believe it runs Mac OSXI may have an iPhone in my future and it'd be cool if I could put

If anyone is interested, I adapted the bayeselo program to GO. bayeselo can take pgn chess files and rate the players. The problem with bayeselo for go is: 1. Rémi's program is interactive - not command line parameter driven. So it's not easy to use inside of scripts. 2. It doesn't un

RE: [computer-go] More UCT / Monte-Carlo questions (Effect of rave)

I also implemented RAVE in Mango. There was a few points of improvements (around 60 Elo points with gnugo as reference), but as much as in the paper of Gelly and Silver :( (around 250 Elo points if I remember well) It might be that the effect of RAVE depends a lot on the simulation strategy. In
