Snowie is a high-quality backgammon program. It is based on proprietary neural network technology that has been trained to play as good as or better than the best human players. Snowie 1 to Snowie 3 used a special learning technique similar to the TD learning algorithm published by G. Tesauro. Snowie 4 however, is based on a new kind of learning algorithm that allowed it to play much stronger than the previous version.
