Dense 768-bit (no HalfKP) double-layer NNUE implementation.
Compile (REQUIRES NIGHTLY RUSTC):
RUSTFLAGS="-C target-cpu=native" cargo build --releaseFor use as a shared library, see nnue/include/prophet.h and target/release/libprophet.so. Docs are included with headers.
For use as a UCI engine, run ./target/release/prophet-nnue. The learn command can be used to create a new net, as long as chess evals are present at chessData.csv in this format:
