#STOCKFISH CHESS PLAY AGAINST COMPUTER CODE#

the precise steps needed will become clearer as we proceed, I look forward to working with the community to make this happen!' We are eager to keep everybody on board, including all developers and users of diverse hardware, aiming to be an inclusive community. This merge will introduce machine learning based coding to the engine, thus enlarging the community of developers, bringing in new skills. 'The NNUE branch maintained by has demonstrated strong results and offers great potential, and we will proceed to merge. In July 2020 chess news reported that Stockfish NNUE had 'broken new ground in computer chess by incorporating a neural network into the already incredibly powerful Stockfish chess engine.' A NNUE merge into Stockfish was then announced and development builds became available. In June 2020, an efficiently updatable neural network (NNUE) fork introduced by computer shogi programmers called Stockfish NNUE was discussed by developers. An official repository, managed by a volunteer group of core Stockfish developers, was created soon after and currently manages the development of the project. On 18 June 2014 Marco Costalba announced that he had 'decided to step down as Stockfish maintainer' and asked that the community create a fork of the current version and continue its development. The last Glaurung version (2.2) was released in December 2008.ДЄround 2011, Romstad decided to abandon his involvement with Stockfish in order to spend more time on his new iOS chess app.

For a while, new ideas and code changes were transferred between the two programs in both directions, until Romstad decided to discontinue Glaurung in favor of Stockfish, which was the more advanced engine at the time. The first version, Stockfish 1.0, was released in November 2008. He named it Stockfish because it was 'produced in Norway and cooked in Italy' (Romstad is Norwegian, Costalba is Italian). Four years later, Costalba, inspired by the strong open-source engine, decided to fork the project. The program originated from Glaurung, an open-source chess engine created by Romstad and first released in 2004. In 2018 support for the 7-men Syzygy was added, shortly after becoming available. The Syzygy tablebase support, previously available in a fork maintained by Ronald de Man, was integrated into Stockfish in 2014. Stockfish supports Chess960, which is one feature that was inherited from Glaurung. (As of December 2021), Stockfish 14 (4-threaded) achieves an Elo rating of 3544 +20 в€’20 on the CCRL 40/15 benchmark.

Compared to other engines, it is characterized by its great search depth, due in part to more aggressive pruning, and late move reductions.

Stockfish implements an advanced alphaвЂ“beta search and uses bitboards. The maximal size of its transposition table is 32 TB. Stockfish can use up to 512 CPU threads in multiprocessor systems.
