Axon (Geniss 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 1. The benchmark indicates how well x86 processors will support Axon's 16-bit instructions.
Description
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 2. 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 3 4. In 2008, Vučković introduced the Compact Chessboard Representation as used in Axon 5 6.
