Re: New AMD Zen 3 and Ryzen processors

I changed the core settings to 8 and I now get 7m nps, which is reasonable for the chip that I have.
For what it's worth I get around 50M nps from starting position with the newest SF on 3970x so it's a bit bigger difference than passmark benchmarks indicate.

Re: Polish users cut off from TalkChess

One easy way to access talkchess from Poland is to download the Opera browser and then enable built-in VPN there.
It still doesn't work using Polish IP unfortunately.

Re: Test position: Neural net blindness.

I've never seen what you describe. You should run Lc0 from a command line, to rule out GUI-related issues. Here are five runs of the position in this thread, with Lc0 terminated after each run. No GUI was used. Default settings, except for Backend = cudnn-fp16. It seems others are confirming unpred...

Re: Test position: Neural net blindness.

I filled an issue on Github about it: https://github.com/LeelaChessZero/lc0/issues/1067 I've signaled it in the past and it seems to me it's not considered a serious problem by the devs. From my perspective it means running Lc0 with more than 1 thread just doesn't work and users who use it for analy...

Re: Test position: Neural net blindness.

Really nice, especially that it comes from a subvariation of a very well known human game and I am sure Kasparov would find 33.Rxe6 quickly. One more time it looks like bug in search. I've already posted about it a few times on both Discord and Lc0 forum. There are positions where it sometimes find ...

Re: NVIDIA RTX 3080, RTX 3070 SPECIFICATIONS LEAKED FOR THE FIRST TIME

If I am reading it right it looks like about 50% improvement. Not very exciting but maybe once they make an appearance prices for 2080ti drop to something reasonable.

Re: Lc0: Kiudee setting is very strong

Any idea if it still holds for very long TCs or does it converge to the same thing given enough time (which would be my intuition).

Re: Can current top engines still be beaten?

What about this game from the tournament? https://www.iccf.com/game?id=974017 Black played solidly but lost. I haven't analysed the game with an engine, but I would assume it would useless to do it anyway without a few days of work I think you are overestimating correspondence players. 41...a5 is a...

Re: Can current top engines still be beaten?

In its way, Stockfish's contempt is a crude way of doing exactly this. A more sophisticated system would also favor imbalance, and any other position characteristics that make finding the best moves harder. If you have enough position - complexity data then you can also train NN to estimate complex...
