Pigeon, an original, experimental 64-bit UCI compliant chess engine by Stuart Riffle, written in C++. Pigeon is open source, released under the MIT license. To support SIMD by SSE2 or AVX2 instructions as well as CUDA for Nvidia GPUs, much of the critical code is branch-free. Pigeon generates sliding piece attacks by Kogge-Stone algorithm. It performs a monochrome move generation approach, color flipping the board after make move , has an iterative search, and used automated tuning of evaluation weights by logistic regression.
