Frozenight - NNUE chess engine written in Rust.
Rating CEDR=2924
v.5.1.0:
This release is a strength improvement of approximately 35 elo compared to version 5.0. This comes partially from improvements in search and partly from an improved neural network. This release will be the last one to feature the very small 32x2 hidden layer which has been used since version 3.0.
The release binaries are categorized by microarchitecture levels. The general rule of thumb is:
x86-64-v3 will work on modern (2015+) CPUs (avx2, bmi1, lzcnt, etc.)
x86-64-v2 will work on older (2009+) CPUs (popcnt, sse4, etc.)
x86-64 will work on any x86_64 CPU.
