PlentyChess - A UCI chess engine with a neural network based evaluation.
Rating Chess Engines Diary CEDR=3714
Building on Windows
For the build to work on Windows, you need to install MinGW as well as the required packages (make, g++, pthread, etc.).
Then you can use the makefile as you would on a unix system.
v.4.0.1:
This is a bugfix release for the Tablebase functionality. Tablebases in version 4.0.0 mostly only work when analyzing FENs, and not during real games.
Binary Guide
generic: Slowest
ssse3: Slightly faster, requires a CPU with SSSE3 support
fma: Faster, requires a CPU with FMA support
avx2: Faster, requires a CPU with AVX2 support
bmi2: Faster, requires a CPU with AVX2 and BMI2 support. Not recommended for Zen1 and Zen2 CPUs
avx512: Faster, requires a CPU with AVX512 support
avx512vnni: Fastest, requires a CPU with AVX512 and VNNI support
neon: For ARM CPUs that support NEON instructions
If you're unsure about what binary to use, start with avx512vnni and find the first one that does not crash on your machine. There is a chance that the AVX2 binary is faster on your system, despite it supporting AVX512.
