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...

Re: Komodo 13.1 Android strange mcts bug?

It's an interesting challenge for MCTS because whatever move you try it will end in a win when you play it out so there is nothing to go by when choosing moves. I think the solution is not obvious but it seems that either counting distance to mate (if you play it out to the end) or using additional ...

Re: Can current top engines still be beaten?

Assuming chess is already softly solved for practical purposes (you can draw with black assuming you have enough resources and time for a move within reasonable realms for both) it seems to me the most interesting project is to find ways which are objectively the best tries to win. There is a concep...

Re: Can current top engines still be beaten?

I've taken a look at the recent World Championship: https://www.iccf.com/event?id=66745 All decisive games resulted from wild gambles by black in the opening, The winner got a huge gift when someone played Mar Del Plata King's Indian vs him (very likely losing opening imo and certainly one you are d...
