Mastering Chess and Shogi by Self-Play with a General ...
arxiv.orgAlphaGo Zero estimates and optimises the probability of winning, assuming binary win/loss outcomes. AlphaZero instead estimates and optimises the expected outcome, taking account of draws or potentially other outcomes. The rules of Go are invariant to rotation and reflection. This fact was exploited in AlphaGo and AlphaGo Zero in two ways.
