Re: [computer-go] Re: Move Prediction and Strength in Monte-Carlo Go

Hi, I would like to confirm your experiments: I have noticed already that adding shapes of radius 4 improves prediction a lot, but does not improve playing strength (from progressive widening). Also, even worse than that, for a given set of features, the pattern urgencies computed by MM

I have been following the scaling study closely. Thanks for everyone for gathering such interesting data and especially to Don and the people donating computers. I have 2 suggestions that could help increase the amount of information gathered from all the CPU hours being used to play these

Hello. Hi, I would like to confirm your experiments: I have noticed already that adding shapes of radius 4 improves prediction a lot, but does not improve playing strength (from progressive widening). I have not yet tuned progressive widening. This information is helpful for my experiments

Re: [computer-go] Scalability study suggestion

i agree with everything except for the seeding. it takes very few games (especially with the distribution you suggest) to get somewhat near the right spot. with 500-ish games being played per player, the initial time to get into the right place isn't unreasonable. keep in mind that if you

Re: [computer-go] Scalability study suggestion

Hi Chuck, Thank you for your interesting suggestions.I have previously considered a system where the distribution is based on how many contestants. For instance if there are hundreds of players you would want to generate best of 5 or 6 or more, but if there were only 3 or 4 you might want

[computer-go] Selecting tree child objects, was Hydra theory (was Hybrid theory)

Hi such question that do you typically traverse all child objects or is there faster way to select explored node child object. I have concluded that it is not at least easy as multiple nodes uct values change each simulation so trying to keep biggest uct value in first in list is maybe too

Re: [computer-go] Selecting tree child objects, was Hydra theory (was Hybrid theory)

It's a shame a priority queue can't be used. But after each simulation, all sibling change together. - Don Harri Salakoski wrote: Hi such question that do you typically traverse all child objects or is there faster way to select explored node child object. I have concluded that it is not

I'm not sure what to think about the following: Leela 0.3.0 vs Leela 0.3.7, 455 game match 177 vs 278 = +78 ELO points for Leela 0.3.7 CGOS rating Leela_0.3.0_1CPU 2335 Leela_0.3.7_2CPU 2333 Hmm..but also Zen-0.9 2386 Zen-1.0 2385 or more: Uct-200801122348 Uct-200801132334
