Re: do top programs find 35.Nb4 right away ...

You don't need a top program on that easy one.

Re: CCRL 40/40, 40/4 and FRC lists updated (23rd February 2019)

For the most part, I believe CCRL currently uses actual time controls closer to 40/20 rather than 40/40 due to the huge advancements made in CPU hardware. A modern quad core at 40/20 would be comparable to a 1050 at 40/20 because even though both pieces of hardware are much newer than the Athlon 46...

Re: Could chess be Solved using Summit plus Leela or AlphaZero

No. Not by that means. To solve a game means that you know a perfect game theoretical outcome from any position. Any engine that uses unsound pruning cannot do this. That includes null move pruning, LMR pruning, and all the other wonderful pruning that gives branching factors of around one and a ha...

Re: Scaling of Lc0

Me again I am quite new with Lc0, but highly interested. What could be the ELO benefit from 1 x RTX 2070 to 2 x RTX 2070 ? In analysis I noticed that the main line does not change after 10 - 20 seconds. So maybe the benefit is very low compared to energy hunger and the investment of a second RTX ca...

Re: Scaling of Lc0

The main question to me is, how does Leela play chess? AB engines calculate, and the more cpu power they have, the more can be calculated (theoretical) Leela seems to be different. Maybe I am wrong, but it seems like Leela is searching in her weights file. BAsed on what can be found there, the actu...

Re: Trying out the Leela Hybrid engine (NN with AB)

Why not let Leela play until there are X pieces left and then let Stockfish take over?
No need for an A/B veto early-middle game.

Re: CCRL 40/40, 40/4 and FRC lists updated (16th February 2019)

Rank Name Rating 45 Lc0 0.20.1 w36089 64-bit 3022 Perhaps it's an idea to include the average NPS in the name for LZ as a sort of indication of the strength of the GPU used. CCRL only uses CPU and its times get adjusted so it's equal to an Athlon 64 4600 running 40 minutes per 40 moves. For my i5-4...

Re: Komodo 12.3 MCTS 64-bit Gauntlets for CCRL 40/40

I hope they keep making 200 Elo improvements. KMCTS has zero future, absolutely none your posts are hilarious (see your post 9 days before): Re: chess programming - predictions for the next 5 years KMCTS is promising too and maybe it will eventually turn out stronger than regular K, maybe this will...
