Axon

a chess engine by primary author Vladan Vučković with chess knowledge and opening moves contributed by Đorđe Vidanović. Geniss Axon, a plain alpha-beta searcher whose development started in 2001, was written in compact 16-bit 8086 assembly, also incorporated into the //Axon Benchmark// program, which is available from the Arena site. The [|benchmark] indicates how well x86 processors will support Axon's 16-bit instructions. || =Description= toc Axon used a 12x12 mailbox to represent the board, and applies a unique move repetition detection technique, as described by Vučković and Vidanović in 2004. Further developments were Axon I, the successor of Geniss Axon XP, first using null move pruning with R = 2, the 32-bit port Axon II utilizing 64-bit MMX extensions, and Axon 3 the serial program of the parallel chess system Achilles. In 2008, Vučković introduced the Compact Chessboard Representation as used in Axon.
