Lizard - UCI chess engine and NNUE
Rating Chess Engines Diary CEDR=3628
v.10.5:
This release makes progress primarily in FRC and short time control games. Most of the gains come from a more well-rounded network (now including ~10% DFRC data) and multiple speedups.
For the sake of my sanity (and because .NET can't/doesn't autovectorize NNUE code), this requires at least AVX2 to be performant, but should still function without it.
Picking a binary:
Start with the non-aot binary, and pick ...-512 if your processor has Avx512.
If you want a slightly slower but more compact binary, start with ...-aot-v4 and use the first one that doesn't crash:
v4 enables Avx512,
v3 enables Avx256,
v2 is a fallback for older CPU's
