Edax 4.4 is one of the best Othello AI in the world.
If I set the game from the very beginning, same line appears a lot. To avoid this, I set the game from many different near-draw lines.
If Egaroucid Win Ratio is over 0.5, then Egaroucid wins more than Edax do. "Black" and "White" means Egaroucid played black/white. In all conditions, Egaroucid is stronger than Edax.
The average number of discs earned indicates how many more discs Egaroucid was able to acquire than Edax on average. The higher this value, the bigger the victory over Edax.
I used XOT for its testcases. No opening books used.
