Abstract

<p>Using optimization to minimize the maximum vote-value disparity and enumeration for the districting problem, we can obtain a lot of candidates of the electoral district. However, it is difficult to choose a good constituency among them. Because there is no indication of other except the gap in the value of votes. The Supreme Court accepts the discretionary authority of the Diet while assuming one vote of difference the most important matter. However, it is difficult to judge whether the exercise of any such discretionary power of the Diet was appropriate. The purpose of this research is to propose a closeness and a degree of divergence as a new index for the decision making and evaluation. The closeness is an indicator to estimate the intimacy level between the municipal districts constituting an electoral district. The degree of divergence is an indicator to measure the degree of estrangement with the current electoral district. In addition, it shows that these indexes are useful in decision-making and evaluation of the validity.</p>
