Computer chess engine, calculates chess moves
Toga II is a computer game chess engine created by Thomas Gaksch. It has big chess knowledge, multi-processor support, and a good search algorithm. It is based on Fruit and is free. Experimental versions of Toga II running on computer clusters have competed in the World Computer Chess Championship.
Chess Programming WIKI:
Toga, (Toga II)
based on Fruit by Fabien Letouzey is a Fruit derivative by Thomas Gaksch, which appeared in early 2005 in test tournaments first without explicit mentioning its Fruit origin. Caused by clone suspicions and announcements, Gaksch apologized to the testers and original author, and continued with the public development Toga II according to the GNU General Public License v2.0.
As official Fruit derivative Toga II was used by Kai Himstedt as primary engine for his GridChess and Cluster Toga entities, competing the WCCC 2007 and WCCC 2008 with Fabien Letouzey and Thomas Gaksch mentioned as co-authors. Toga II 1.4.1SE by Chris Formula based on Toga II 1.4beta5c by Thomas Gaksch featured a parallel search where multiple threads share the hash table - a kind of early Lazy SMP. Toga CMLX is a Chess960 capable version by Teemu Pudas. Further development was done by Michel Van den Bergh, porting Toga II to Linux, subsequent Toga II versions were maintained by Jerry Donald, Toga Returns based on Toga II by Ben Tennison, while further Toga II offsprings were Grapefruit by Vadim Demichev, and Cyclone and TogaToy by Norman Schmidt.
With the advent of NNUE, Dietrich Kappe released Toga III 0.4 NNUE with a net based on depth 8 data from Toga II 4.0.2 [12] [13].
🌍️ Wikipedia:
Fruit is a chess engine developed by Fabien Letouzey. In the SSDF rating list released on November 24, 2006, Fruit version 2.2.1 had a rating of 2842. In the CEGT rating list released on January 24, 2007, Fruit version 2.2.1 had a rating of 2776.

Derivatives
Although in 2007 Fabien Letouzey stopped the development of Fruit with version 2.3.1, the earlier open source 2.1 version provided the basis for many other programs.
Toga II
Toga II is a derivative created by Thomas Gaksch, currently continued by Jerry Donald Watson. It has more chess knowledge, multi-processor support, and perhaps a better search algorithm. It is based on Fruit 2.1 and is free. The strongest version is Toga II 4.0, released on 29 December 2017 by Jerry Donald Watson. Experimental versions of Toga II running on computer clusters have competed in the World Computer Chess Championship (WCCC). At about 80 ELO above Fruit 2.3.1, Toga II is the strongest Fruit derivative as of March 2014.
In 2008, forks of Toga II started to appear, like Grapefruit and Cyclone.

Moteur de jeu d’échecs pour le calcul des mouvements
Toga II est un moteur de jeu d’échecs conçu par Thomas Gaksch. Il possède une solide base de connaissances de jeux, un bon algorithme de recherche et prend en charge plusieurs processeurs. Il est basé sur Fruit et est libre. Des versions expérimentales de Toga II utilisées sur des grappes d’ordinateurs ont concourues lors du championnat mondial de jeu d’échecs pour ordinateurs.

Programmes dérivés
Fruit étant un logiciel libre d'un niveau de jeu proche de celui des logiciels propriétaires, de nombreux programmes dérivés de son code ont été édités de façon plus ou moins légales. La notion de copyleft inhérente à la licence GNU GPL impose aux programmes dérivés les mêmes conditions de redistribution que le logiciel libre source. Parmi les programmes dérivés de Fruit on peut citer :
GNU Chess.
Toga II.
Thomas Gaksch publie en 2005 Toga II, un programme qui dès sa première version est d'une force comparable à celle des logiciels propriétaires, ce qui provoque des soupçons dans la communauté des échecs électroniques. On pense avoir affaire à un clone de Shredder ou de Fritz. Thomas Gaksch avoue la supercherie et publie son code source. La dernière version libre de Fruit datant de 2005, Toga II est maintenant développé à partir du code source de Glaurung, autre fork libre, Thomas Gaksch ayant réussi à faire cohabiter les deux algorithmes.

Pour jouer avec ce moteur, utilisez une interface graphique de jeu telle que (testé & validé): Glchess, pychess.
Sous Debian, les Moteurs de jeux d'échecs empaquetés sont installés dans /usr/games/ (information utile pour le paramétrage des interfaces graphiques).
