Abstract

In this paper, we consider LR\mathcal{L}\mathcal{R}-ending partisan rulesets as a branch of combinatorial game theory. In these rulesets, the sets of options of both players are the same. However, there are two kinds of terminal positions. If the game ends in one of the terminal positions, then a player wins and if the game ends in the other terminal position, the other player wins. We introduce notations for positions in LR\mathcal{L}\mathcal{R}-ending partisan rulesets and show their algebraic structures. We also introduce some examples of LR\mathcal{L}\mathcal{R}-partisan rulesets and show how our results can be used for analyzing the rulesets.
