What is Craft?

Craft is an Othello program with relatively strong artificial intelligence. It uses techniques including pattern-based evaluation model, bit-board representation, Multi-Prob Cut, NegaScout, iterative-widening End-Cut and self-learning opening book. Craft can look forward 16~20 steps in mid-game, and up to 24 steps perfect endgame.

Craft's AI has now reached almost the same level as the famous Othello program 'Shang Xin Hei Bai Qi'.
