A toga [1]

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 [2] , Gaksch apologized to the testers and original author [3], and continued with the public development Toga II according to the GNU General Public License v2.0.

As official Fruit derivative [4] 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 [5] [6]. Toga CMLX is a Chess960 capable version by Teemu Pudas [7] [8] [9]. Further development was done by Michel Van den Bergh, porting Toga II to Linux [10], subsequent Toga II versions were maintained by Jerry Donald, Toga Returns based on Toga II by Ben Tennison [11], while further Toga II offsprings were Grapefruit by ThinkingALot, 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].
