Matefinder is a Stockfish derivative maintained by Joseph Ellis with the objective to solve chess problems and find moves that lead to checkmate rather than playing complete games.
I hope i'm not wrong about the source code commit date. I had to collect it from the maintainer's page because the Android build doesn't show any version information.
