Edax is an Othello-playing computer game, capable of playing the game at difficult levels, similar to how others computer games are chess-playing computer games. Edax was written by Richard Delorme in 1998.

Edax utilizes various algorithms. Notably among them are: bitboard move generator, negascout tree search, multi-probcut selective search,[1] parallel search using the Young Brother Wait concept,[2] and pattern based evaluation function.[1]
