New chess engine: Saturn 1.1

on

 


Saturn 1.1 - UCI chess enegine

v.1.1:
The new version with NNUE evaluation, a few bugs fixed, several added, the usual stuff. I estimated it to be in the 2900-3000 CCRL elo range, which is almost a +300 elo simply by replacing PSQT evaluation with an okay-ish NNUE.

The NNUE file must be in the working directory to be automatically loaded (if it doesn't get picked up automatically, the engine will tell so in the console and abort on first attempt to evaluate). You can specify the absolute path to weights manually with the UCI option evalfile.

There are two executables available: one for AVX2 and one for SSSE3. The AVX2 is slightly faster and thus preferable. Also, I don't really have access to an old cpu so I never managed to see if SSSE3 version actually runs on an old cpu.

UPD: hotfix for a crash when the game is longer than 512 plies (or 256 full moves). This bug has apparently been present since day one...
