Revision as of 17:06, 29 March 2020
chess4j,
an open source chess engine by James Swafford using Java based technologies
and the Chess Engine Communication Protocol, released under the MIT License,
and first published in September 2012 [1].
The engine was hosted on SourceForge, and meant to be a test bed for various interests, including experimenting with different JVM based languages, parallel and distributed programming techniques, and machine learning.
Since version 3.2 released in March 2017, chess4j became a bitboard engine, using magic bitboards to generate moves [2], now hosted on GitHub.
