Cooperative Ruling Sets and Its Applications

首先，在扩展形式博弈的框架下，对自己提出的一维空间投票模型进行了重组。通过这种重新组织，我的理论与其他人的结果之间的关系变得清晰起来。在此基础上，我一举完成了以下三个方面的贡献：1.提出了政党政策定位的方法；2.解决了计算1.3项的各种计算困难；3.实证表明，该方法的计算结果真实地解释了日本全国大选的实际问题。目前，空间投票理论缺乏连接理论和现实世界的说服力工具。我的结果有望给这个问题带来突破。

First of all, I reorganized the one-dimensional spatial voting model proposed by myself in the framework of extensive-form game. By this re-organization, the relationship between my theory and the results by others became clear. Based on this results, I successfully completed the following three contributions at one effort.1.I proposed the method for determining the location of the policy of political parties.2.I solved various computional difficulties in calculating the item 1.3.I empirical showed that the results by this approach really explain the actual issue of national election in Japan.Up to now, spatial voting theories lack the persuasive tool for connecting the theory and the real world. My result is expected to give a breakthrough to the problem.
