情報処理学会 第73回全国大会講演要旨

Next, I pursue 3RO board. Analyzing each stone piece (a bulk or group of same color stones) is required by increasing board figures. On the board KOU newly happens, so I add 6) KOU rule to elder five rules [1]. The continuity of each state (turn and figure) forms an eight-branch tree, whose longest branches exceed hundreds hands, each nodes generated about twice by a hand. I also find figures and flows which appear on 19RO board very much. To make ME (eye) at corner is most important, because the game ends in a draw at KOMI = 7 or 8.
