#Stockfish chess mcts code

A staff member named Dmitry Pervov joined the Dragon development team to write the NNUE code for Dragon, and Dietrich Kappe joined the Dragon development team to help Larry Kaufman and Mark Lefter train Dragon's neural networks. Dragon is also called Komodo Dragon in certain tournaments such as the Top Chess Engine Championship and the World Computer Chess Championship (WCCC) but not in the Computer Chess Championship (CCC). Dragon is derived from Komodo in the same way that Komodo was derived from Doch. On November 9, 2020, Komodo Chess released Dragon by Komodo Chess 1.0, which features the use of efficiently updatable neural networks in its evaluation function. The latest version, Komodo 14.1, was released on November 2, 2020. On December 17, 2018, Komodo Chess released Komodo 12.3 MCTS, a version of the Komodo 12.3 engine that uses Monte Carlo tree search instead of alpha–beta pruning/ minimax. The Komodo team is now called Komodo Chess.

On May 24, 2018, announced that it has acquired Komodo and that the Komodo team have joined. Komodo 7 was released on May 21, 2014, adding Syzygy tablebase support. This was the same version that had won TCEC Season 5, and was the last with input from Don Dailey, to whom it was dedicated. Komodo TCEC was released on December 4, 2013. On October 8, Don made an announcement on the Talkchess forum that Mark Lefler would be joining the Komodo team and would continue its development. With the release of Komodo 6 on October 4, 2013, Don Dailey announced that he was suffering from an acute form of leukaemia, and would no longer contribute to the future development of Komodo. This version, named Komodo CCT, was still based on the older C code, and was approximately 30 Elo stronger than the 5.1 MP version, as the latter was still undergoing massive code-cleanup work. A single-processor version of Komodo (which won the CCT15 tournament in February earlier that year) was released as a stand-alone product shortly before the 5.1 MP release. This version was a major rewrite and a port of Komodo to C++11. The first multiprocessor version of Komodo was released in June 2013 as Komodo 5.1 MP. Komodo was derived from Don Dailey's former engine Doch in January 2010.
