![]() We believe Dragon MCTS can benefit from as many as 64 threads and that it benefits from using many threads as much as standard engines do. We believe that Dragon is the strongest Monte-Carlo engine for most personal computers without high speed GPUs, and is among the top three CPU-based engines. Compared to Komodo 14.1 the gains are roughly just ten elo less. In both standard and MCTS modes, Dragon is about 200 elo stronger than Komodo 14 on one thread and about 170 elo stronger on four threads, based on direct matches at the CCRL blitz time control of 2’ + 1”. Komodo, the Dragon predecessor, has won many highly respected engine tournaments multiple times, such as TCEC, CCT, the World Computer Chess Championship, the World Blitz and the World Rapid championships. Dragon supports multi-core computers and endgame tablebases. Dragon is a huge improvement over all previous Komodo versions, in both standard and MCTS modes, achieved by incorporating the new “NNUE” technology originally developed for the game of shogi.
