Update, 2000 games are played. http://cegt.forumieren.com/t1042-testing-komodo-12-2-1-x64 Best wishes, G.S. (CEGT team) We have confirmed that there is a bug in 12.2.2 MCTS in MP mode as reported by CCRL, and have a fix for it at least in the position shown. Fortunately this bug does not affect sin...

Re: Komodo MCTS scales worse with TC than Komodo A/B?

We already found and fixed a bug that was probably related to the crash, although I'm not sure that the problem is fully solved yet. I think that it is likely that the huge number of threads rather than the long time control may be related to the problem. I've seen at least four crashes (out of abo...

Re: Komodo MCTS scales worse with TC than Komodo A/B?

Komodo 12.2 MCTS just hit the FastGM rating list at bullet time control - http://fastgm.de/60-0.60.html It places right between Ethereal 11.00 and Fire 7.1. On the complete list it ranks exactly one place above Komodo 9 :D TCEC Division 4 will be a good test of how it performs at long time control....

Re: Komodo MCTS scales worse with TC than Komodo A/B?

Ten seconds on four thread as typically equal to 30 seconds on one thread. Interpolating between your peak results at ten and 30 seconds (logarithmically) gives Komodo MCTS a bit over 46 at that level, a point more than the very strong Fire 7.1 but 7 below Ethereal 11, rated a bit below Komodo 12.2....

Re: Komodo MCTS scales worse with TC than Komodo A/B?

Thanks for running this. I don't think that the poor scaling is inherent to MCTS, rather it's just that we have tuned our parameters at levels around 3 seconds a move or so and that means that they will be poorly tuned for time controls far from that level. So I have to start doing some tuning runs...

Re: Komodo ChessBase question

PayPal takes Euros as well as dollars. We don't have ChessBase 8 anymore, too old, so we can't test on it.

So 3188 compared to my result of 3188 vs. Ethereal, difference zero!
