Komodo
Komodo logo [1] Komodo,
a chess engine by primary author Don Dailey (died at the age of 57 on November 22, 2013) and since October 2013, by Mark Lefler, supported by chess advisor and evaluation expert and Don’s long time collaborator Larry Kaufman. Since 2015, opening book expert Erdogan Günes is responsible for Komodo’s book moves. At the WCCC 2016 Komodo 10.x first time won the Shannon Trophy, defended by subsequent versions at the WCCC 2017, WCCC 2018 and WCCC 2019 so far. In November 2020, the Dragon by Komodo Chess was released, featuring NNUE technology.
Komodo appeared in January 2010 derived from Don’s former engine Doch. It uses bitboards as internal board representation, and has a sophisticated search and a knowledge based, balanced evaluation. Komodo is a standalone chess engine supporting the UCI protocol and is available for multiple platforms and operating systems, and is therefore compatible with free and commercial UCI compliant chess graphical user interfaces and database front ends.
As of December 2011, Komodo became commercial with version 4 [2], earlier versions running under Windows, Linux, Mac OS and Android are available from the Komodo download site, free for non-commercial use [3] [4]. Next release date was May 2013, with CCT15 winner Komodo CCT [5].
Komodo 5
Komodo 5.1 MP, released in June 2013, was a major rewrite in C++11, able to perform a parallel search to run on multiple processors [6] .
Komodo 6
In October 2013, Don Dailey announced the release of Komodo 6 and also bad news concerning the future status of Komodo due to his fatal illness of a acute form of Leukemia [7] . He introduced Mark Lefler as new member of the Komodo team [8] [9] . Don Dailey died November 22, 2013 at age 57, just about the same time that Komodo pulled ahead of Stockfish by winning game 2 in the TCEC Season 5 final [10] [11] .
Komodo TCEC and 7
As winner of the TCEC 5 final, Komodo TCEC was released on December 04, 2013 [12], the further improved Komodo 7 on May 21, 2014, now supporting Syzygy Bases [13], probing code interface implementation by Jeremy Bernstein [14].
Komodo 8
Komodo 8, released on September 05, 2014, was a substantial improvement over Komodo 7a, which was already rated among the top three chess engines on almost all rating lists [15]. Komodo 8 supports Syzygy Bases and is available for Windows, Linux, Mac OS and Android, the latter immediately available for import in Chess for Android and in Chess for Glass [16]. Since mid September 2014, Komodo 8 for Windows is available as ChessBase engine, bundled with the Deep Fritz interface, Syzygy bases not included [17].
Komodo 9
Komodo 9, released on April 28, 2015, continued the progress with approximately +50 Elo over Komodo 8 due to improved search, evaluation, and time management, as well as more efficient use of multiprocessing [18]. Most noticeable is the increase in search depth reached in a given amount of time, which is due to better extension, reduction, and pruning rules [19]. Further, Komodo 9 now features Chess960 and a persistant hash to save and restore analysis.
Komodo 10
On May 23, 2016, Komodo 10 came with revised and improved king safety, pawn storm and passed pawn evaluation, as well with revised LMR, NMP, IID and history heuristic concerning search, and is about 60 Elo stronger than Komodo 9 [20]. In July 2016, Komodo 10.x won the Shannon Trophy.
Komodo 11
On May 23, 2017, Komodo 11.01 was released, which corrected some minor issues of Komodo 11, which was already released by ChessBase a few days before. It is estimated about 55 Elo stronger than Komodo 10 at intermediate time controls, gains related to evaluation [21], revised quiescence search, singular extensions, LMR , and parallel search [22] . Komodo 11.2, released on July 17, 2017, was the version which won the WCCC 2017 [23]. Komodo 11.3 was released on March 04, 2018 with subsequent improvements [24]. It also comes with a BMI2 compile for compatible x86-64 processors - so far not recommend for AMD Ryzen due to its slow PEXT implementation [25].
Komodo 12
Komodo 12 was released in May 2018. Beside the classical, slightly improved engine, Komodo 12 features an optional Monte-Carlo Tree Search (MCTS), the release likely influenced by the AlphaZero hype. However, as confirmed by Mark Lefler [26] implementing MCTS was already an old idea of the Komodo team - also due to Don Dailey’s computer Go experience building an UCT player.
Komodo MCTS
In Komodo’s MCTS mode the search tree is expanded in best-first manner based on winning probabilities determined neither by random playouts nor by a neural network, but a tiny alpha-beta search plus quiescence and static evaluation, also similar to UCT, dealing with the crucial trade-off between exploration and exploitation. While playing strength is lower with MCTS, positional play and judgement may well be better in many positions [27], not to mention a more risky and entertaining playing style.
Komodo 13
In May 2019, Komodo 13 was released with substantial improvements in MCTS mode. Quote by Larry Kaufman [28]:
Komodo 14
Komodo 14, released in May 2020 with following improvements announced by Larry Kaufman [29]:
Dragon
Along with the release of Komodo 14.1 on November 02, 2020, Larry Kaufman announced Dragon, featuring NNUE technology due to support of Dietrich Kappe and Dmitry Pervov, applied and trained with Komodo games and evaluation [30]. Improvements for both standard and MCTS mode are expected in the 150 to 200 Elo range. Dragon by Komodo Chess was released on November 10, 2020 [31].
Tournament Play
Komodo played the ICT 2010 in Leiden over the board, and further the CCT12 and CCT14. It had its first tournament success in 2013, when it won the CCT15 with 6½/7, and further the CCT16 in 2014 with 5½/6.
TCEC
In 2013, Komodo started to play the TCEC, most often fighting with Stockfish for the title. Komodo won the TCEC Season 5, TCEC Season 7 in 2014, and the TCEC Season 8 in Fall 2015.
WCCC / WCSC / WCRCC
2015
At the WCCC 2015 in Leiden, Komodo 9.x won the Blitz tournament, and became runner-up behind and losing from the massively parallel and distributed Jonny which played on a cluster of 100x24 cores. After the revenge winning against Jonny at the equal hardware WCSC 2015 a few days later, Komodo was unlucky and made too many draws against apparently weaker opponents [32], to became third behind Shredder and Ginkgo. Two weeks later, Komodo won the WCRCC 2015 convincingly with 9/9!

2016
The 2016 ICGA tournaments in Leiden were a huge success for Komodo 10.x, which did not only won the Shannon Trophy in the open hardware World Computer Chess Championship after a nerve-racking six games play-off versus defending champion Jonny - Komodo with 48 threads on 60 core Intel i7 versus Jonny’s cluster of 100x24 AMD cores, but also the equal hardware World Chess Software Championship with 5/6 - 1½ points ahead of runner-up Jonny and Shredder. Two weeks later Komodo defended its ACCA title in rapid chess at the WCRCC 2016 with 14 wins and one draw versus runner-up Andscacs, that is 14½ out of 15.

2017
In 2017, Komodo could defend it titles at the WCRCC 2017 online, and the soon later released Komodo 11.2 the ICGA WCCC 2017 over the board, again in a play-off versus Jonny. Komodo further became runner-up at the uniform hardware WCSC 2017 behind Shredder.

2018
In 2018 Komodo 12 continued its success by winning the ICGA WCCC 2018, WCSC 2018 and Blitz tournaments in Stockholm, and later that year the WCRCC 2018 online.
2019
Komodo 13.1 [36] was able to defend both titles at the ICGA WCCC 2019 and WCSC 2019 in Macau, the WCCC on a 128 cores.
