Chess Forum

I dont think poster in another forum meant this to be humorous but man .. :laughing-rolling:

a new network came out -1b951f8b449d.nnue
- I put it in the engine and lost 2 games
in a row on PlayChess in chess. Why is this ?
Maybe in the engine settings in the Use NNUE
window you need to uncheck

Make posix and msys2 shells consistent in CI

In CI, it is typical for the process to halt immediately when an error
is encountered. However, with our `shell: bash {0}` configuration,
the process continues despite errors for posix shells.
This commit updates the behavior of posix and msys2 shells to ensure
consistency in terms of pipeline exit codes and stop conditions.
We adopt the most appropriate default behavior as recommended
by the GitHub documentation.

Update the code that searches for the bench value in the git log:
- to be compatible with the new shell settings
- to retry the value from the first line that contains
only the template and spaces/tabs/newlines

Ops.... I beg you pardon. I didn't see it and I was excited for the news.

Update default net to nn-c38c3d8d3920.nnue

This was a later epoch from the same experiment that led to the
previous master net. After training, it was prepared the same way:

1. greedy permuting L1 weights with https://github.com/official-stockfish/S ... /pull/4620
2. leb128 compression with https://github.com/glinscott/nnue-pytorch/pull/251
3. greedy 2- and 3- cycle permuting with https://github.com/official-stockfish/S ... /pull/4640

Local elo at 25k nodes per move (vs. L1-1536 nn-fdc1d0fe6455.nnue):
nn-epoch739.nnue : 20.2 +/- 1.7

Generate binaries for more advanced architectures

use intel's Software Development Emulator (SDE) in the actions that build the binaries.
This allows for building on Windows and Linux binaries for
- x86-64-avx512
- x86-64-vnni256
- x86-64-vnni512

(x86-64-avxvnni needs more recent gcc in the actions)

also build x86-64-avx2 on macos.
