Because the Neural Net in Lc0 is bigger than the one in SF NNUE, do we have any examples of where Lc0 evaluates a position better?
I'm thinking of positions where a deep AB search won't help much, such as blocked positions.
Search found 1319 matches

Re: using 3,5,7cores
I remember Houdart saying it was fine. I also typically use an even number of cores doubling from 2, but that's more out of habit than something rational.

Re: Next-Gen GPUs for LC0
I wonder how a head to head would go between the 3090 and 2x2080Ti for Lc0. I guess running off one card would be quite a big advantage

Re: Next-Gen GPUs for LC0
Although it's not stated, surely that means FP16 on CUDA alone will be 71 TFLOPS, no? That's well over 2x performance increase for Lc0..

Re: Black moves first ...
Actually black moves first is being seen as an anti-racist idea, based on the assumption chess promotes white privilege (white moves first).

Next-Gen GPUs for LC0
Concerning speedup for Lc0: With Nvidia Ampere on its way pretty soon I've been looking into leaked and (take with a pinch of salt etc etc) early reports suggest actually it's nothing special. Performance per watt looks surprisingly similar to Turing, with the new cards sucking 350W each rather than...

Re: MCTS vs Alpha-beta
With Lc0 a lot of the attention went on the NN and how it was better than a hand-crafted Evaluation Function. But I'm trying to understand the search side of things. I have a basic, layman's, working knowledge of alpha-beta search in chess and virtually no real understanding of MCTS, which I think ...
