Re: Official: Lc0 is the strongest engine :)

On my fair price-wise hardware in openings and middlegames . My GPU is GTX 1060 6GB and CPU is 4 core i7 4790 at 3.8 GHz. Lc0 18.1 ID11261 is using 2 CPU threads and GPU Stockfish_dev is using 4 CPU cores (4 threads). Seeing how badly Lc0 underperforms in endgames (more than 350 Elo points weaker t...

Re: OT: Rise of GandCrab virus

We can defend our important programs and data against every harmful program if we have a PC - even an older one - what we use only for internet. The downloaded and controlled materials we can transport to our main PC what we use for works, for chess engines, for etc. with the help of a USB stick or ...

Re: Chess.com 2018 computer chess championship

I think the issue is that LC0 plays very well, except for a glaring hole that almost any opponent can capitalize on. Other engines have their own holes, but they are subtle, so weaker engines are less likely to discover them. So we can say LC0 capitalize the weaker positional knowledge of AB engine...

Re: leela is official(?) better than sf9

AB engines are tested mainly for middle game. NN engines play learning games from start position so their knowledge decreases going further from start position. These facts cause that starting the games from a sort opening book or without opening book is favorable for NN engines and disadvantageous...

Re: Chess.com 2018 computer chess championship

Hyper threads can use only the unused resources of the processor. So it yields plus Elo only if the processor is not overclocked. Lol, again you with those ridiculous claims. You don't even understand what overclocking actually means. Overclocking and hyperthreading are two completely orthogonal wa...

Re: Chess.com 2018 computer chess championship

Hyper threads can use only the unused resources of the processor. So it yields plus Elo only if the processor is not overclocked. I think it would be good policy if they would be used dedicated threads: main threads for thinking and hyper threads for pondering only. Or one half of the whole threads ...

Re: Leela (lack of) endgame technique?

Leela Chess Zero - like AlphaZero - has no any "technique". Chess engines based on Neural Network have only a memory with big capacity and a searching motor (MCTS) to find appropriate move memorized during learning cycle for the analyzed position. Physically the measure of NN memory is not big (some...
