Chess engine: Seawall 20231015

on


Chess engine: Seawall,
Rating CEDR=2827  Author - Patrick Heck

This is an [UCI] chess engine. It started as an attempt to build a minimal program that was able to play chess. Over time, it has gained features to make it stronger, but it still implements only a subset of UCI necessary to play games, and there's almost no evaluation.

Some ideas have been borrowed more directly than others; the obstruction difference algorithm is based on the version from [Chess Movegen], while the use of a low pass filter and capture history for move ordering were borrowed from [Stockfish].
