The program includes +an AI (Artificial Intelligence) opponent which plays at a very challenging +level and is actually quite hard to beat. The AI opponent's strength can +therefore be adjusted in several ways to give you a suitable opponent. + +The AI opponent uses a plain alpha-beta search with hashing to figure out +which move to make. To be able to tell a good position from a bad one, it +uses a pattern based evaluation function. The pattern used is the 9 discs +surrounding each corner and the 8 discs creating the edge of the board. +The evaluation function also takes mobility, potential mobility and parity +into count. For the initial 9 moves the AI opponent optionally uses a +simple opening book. During midgame it searches and evaluates about +200.000 nodes per second on a PIII 750 MHz, in the endgame this number is +significantly higher due to more transpositions and a less expensive +evaluation function. |
