I still don't understand your point. Are you just trying to say computers have a long way to go to beat really strong humans? If so, that doesn't have anything to do with what Chrilly said or my response to him. On Wed, 2007-01-10 at 19:10 -0800, steve uurtamo wrote: > i'm saying that if

We generally use level 10 or 12. We have found that very rarely on level 15 GG will run off into the weeds, never (longer than 24 hours) to make a move. This has also been reported by others at level 18. We have never seen this happen at level 10 or 12. Cheers, David On 10, Jan 2007, at

I would suggest the minor correction to say that any non-GNU based program would have this hope. SlugGo already does this, but I doubt it has this meaning. Cheers, David On 10, Jan 2007, at 4:38 PM, steve uurtamo wrote: as an example, if any program could give gnugo 9 stones under these circ

i'm saying that if a factor of 50 extra time can make your program strong enough to be 'impressive', then you know that you're within a reasonable hardware 'scaling distance' of playing that strong at regular timeframes. if, on the other hand, you're *not* (which would be easy to see by performing

in absolute terms, the time issue doesn't matter until some piece of code is good enough to beat a dan-level player on a 19x19 board at *any* physically realistic time constraint. which hasn't yet been demonstrated. the super slow motion tournament would be a good way for us to notice when this ha

Chrilly, The computer go guys don't think of performance as a function of time, only as a kind of absolute, it plays good or it doesn't. Us computer chess people are used to thinking of it as a function of how fast the computer is and how much memory (along with how well the code is written of

Hello, in my experiments of MoGo against Gnu-Go (in 19x19 of course), with some parameters making 65% win against GnuGo 3.6 level 8, I have 59% against GnuGo 3.7.10 level 8, and 52% against GnuGo 3.7.10 level 16. The confidence intervals are quite small as there are between 500 and 1000 games. S

You must test with Gnu-Go level 16.. This is according to Stefan Mertin by far the best mode. But it takes sometimes quite a long time till Gnu-Go makes it move. In your experiments Gun-Go played very fast. You played fast Blitz and Gnu-Go had a big time handicap (besides Handtalk, which plays U

It is possible that Your uniform playout part is a lot more efficient than UCT part, because of costly move choosing procedure (loop). On last Computer and Games conference I and Jakub Pawlewicz published an article describing 1+epsilon trick that increases efficiency of proof-number search. It

Hello, Also on 19x19 mogos plays also some very slow moves in the beginning of 7 handicap game. I guess that using (average_score / standard_deviation_of_score) instead of (winning_probability) should solve both problems at the same time. yes you're right, MoGo is very weak in the opening gam
