LcFiSh LcFish

LcFiSh introduces NNUE technology into the lc0 ecosystem. As the NNUE code greatly benefits from the latest processor features the arch build option was added to specify the processor architecture, as in the following example: CXX=g++-9 CC=gcc-9 ./build.sh -Darch=x86-64-avx512-vnni Use meson configure to see the accepted values.

Code:

https://github.com/borg323/lc0/releases/tag/lcfish


(Edit) Sorry. Did not see the engine listed in the Stockfish thread.

I downloaded but it doesn't work for me either "modern" or "avx"... -:(

Confirm this baby works in Arena 3.5.1, it is very strong n probably stronger than Stockfish Development version.

what are you talking about? the last time I tested it was 70 elo behind Cfish 040121
It is very weak compared to top engines..

Under this testing conditions:

1) I m using lcfish-x86-64-modern.exe
2) I m using nn-0e698aa9eb8b.nnue (the steroid)
3) I m using silversuite.pgn which consists of 50 openings selected by Albert Silver

Yeah the secret to LCFish right now appears to be finding the right Stockfish net. The nets trained by LCFish itself seem to be very weak.

LcFish is Cfish 01.04.2021 engine with lc0 trained net which is different and ~50 elo weaker than default Stockfish trained net

It doesn't make sense changing the net because the whole point of this LcFish engine is to try new network based on 200 million positions extracted from t60 training data

Really hard to believe this..

Lcfish beaten SugaR AI 2.00..

50.5 to 49.5.. The smallest margin possible..

Those non-believers can do more testing on this..

The main thing is to be able to connect the network to the engine.
I recommend taking the engine without the built-in network, then rename this network to nn-62ef826d1a6d.nnue and put it next to the engine. Or specify the full path in the engine parameter
