Outline of Final Research Achievements

The main result of this project is the paper published in Information Processing Letters 139 (2018), pages 13-17. Its DOI is https://doi.org/10.1016/j.ipl.2018.06.013. In this paper, we investigate algorithms, including non-depth-first ones, against independent distributions. We proved that an equilibrium point among independent distributions has optimal algorithm that is depth-first. By means of this theorem, we give positive answers to the questions in Suzuki-Niida (2015). In addition, we extend theorem 3 of Peng et al. (2017) to the non-depth-first case.

Academic Significance and Societal Importance of the Research Achievements

将棋やチェスのような二人ゼロサムゲームを計算機に行わせる際,ゲームがどんな風に進んでいく可能性があるかは,ゲーム木という樹形図で表現される.計算機はゲーム木を探索する.プログラムの実装はもちろん重要ではあるがそれらとは別に,ゲーム木探索について数学的な原理を探求するのもまた重要である.本研究が明らかにしたAND-OR木に対する諸定理は,ゲーム木探索の数学的な礎となるものである.とくに深さ優先でない探索についての定理が主要な成果である.
