New chess engine: HypnoS.legacy 180824 (derived from Stockfish)

 

HypnoS is a free and strong UCI chess engine derived from Stockfish that analyzes chess positions and computes the optimal moves.

HypnoS does not include a graphical user interface (GUI) that is required to display a chessboard and to make it easy to input moves. These GUIs are developed independently from HypnoS and are available online.

HypnoS development is currently supported on the Openbench framework. OpenBench (created by Andrew Grant) is an open-source Sequential Probability Ratio Testing (SPRT) framework designed for self-play testing of engines. OpenBench makes use of distributed computing, allowing anyone to contribute CPU time to further the development of some of the world's most powerful engines.
