Aristides is a C port of the Stockfish chess engine, forked from Cfish by Michael Byrne.
It includes play by UCI_LimitStrength (play by ELO rating), UCI Move Delay, Fast Play when mate is found, Study option (from Matefinder), Hide Info ( some information output may be skipped to reduce output) and various search tweaks.
I guess that we owe THIS Android port to Alexei Chernakoff, the only active build maker nowadays. The package features arm7 builds only.
