Kei Takada [1]
Kei Takada,
a Japanese computer scientist affiliated with the Graduate School of Information Science and Technology, Hokkaido University, Sapporo, Hokkaido.
Ezo
Along with Masaya Honjo, Hiroyuki Iizuka, and Masahito Yamamoto, Kei Takada is author of the Hex playing program Ezo, which played the 17th Computer Olympiad in Yokohama 2013, and the 18th Computer Olympiad in Leiden 2015. Ezo uses 2-ply alpha-beta search with an evaluation function based on the theory of complex networks. The function combines a betweenness measure of the player’s two sides with a shortest path metric that accounts for the degree of important nodes, further elaborted by Kei Takada at the Advances in Computer Games 14 conference in Leiden 2015 [2]. EZO switches to a Hexy-style evaluation when remaining time becomes short [3]. Ezo-CNN, which played the 20th Computer Olympiad 2017, uses a convolutional neural policy network for move ordering [4] [5].
