Re: Lc0 on RTX 2080 Super

Speed ranging from 17 to middle of 30s into 50 kilo nodes per second. Network is 128x10-2019_0812_1326_54_239 - is it good and is there any better at this point? Wrong speeds for that smallnet and 2080 Super. On your GPU, JHorthos 256x20b latest nets are the strongest to rapid TC, and his latest bi...

Yes, but Lc0 hardly scales beyond 2 GPUs.

Re: Out of the Kai 450 positions, 99 not found by SF

I think that it may be interesting if somebody throw away all opening theory and replace it with stockfish analysis with a lot of computer time and see if other books can beat this book. Yes, I maybe will do such a thing in 2 LTC games. Lc0 with "bignet", which seems to agree by far the most with t...

Here are the results on these two suites at exactly 10s/position, Openings200revised (200 positions) and Midgames239 (239 positions) tested today. RTX 2070 GPU, 4 i7 3.8GHz cores.

Re: Out of the Kai 450 positions, 99 not found by SF

Well, for the first position on Dann's list, it seems that Cfish-dev and Lc0 (42850) both prefer Rac1. I'm curious to try an Lc0 "bignet". What is that and where can I obtain one? Here's Lc0 after 250M nodes: info depth 30 seldepth 82 time 4483899 nodes 131704920 score cp 87 hashfull 620 nps 29372 ...

Re: Out of the Kai 450 positions, 99 not found by SF

<snipped> What is so bad about openings and humans? Most of opening theory to our days is built by humans, engines' contribution is small and mostly came with "tricks", and often in messy positions. I think you just imply that we can throw away all opening theory and replace it with Stockfish analy...

Re: Out of the Kai 450 positions, 99 not found by SF

I think that if we claim that stockfish does not find the right move then we need some evidence that the move we claim to be better is really the better move(for example some tree that if we go forward and backward in the tree stockfish can learn to play the right move). It's almost like saying tha...

Re: Out of the Kai 450 positions, 99 not found by SF

I think that if we claim that stockfish does not find the right move then we need some evidence that the move we claim to be better is really the better move I checked to see when exactly I built Openings200, it was built almost 3 years ago. It could have been easily proven junk by Lc0 when it arri...
