Computer Chess

While affiliated with the Department of Systems Engineering at Australian National University, Jonathan Baxter co-authored the TD-learning chess program KnightCap ^[7] and further wrote his own engine TDChess based on KnightCap ^[8], which won the NC3 1999 Australasian National Computer Chess Championship ^[9]. After the AlphaZero incident in December 2017, Jonathan Baxter contributed a Monte-Carlo Tree Search wrapper for Stockfish ^[10].
