Abstract
A low voter turnout came to be a problem in Japan recently. In addition, some local governments in Japan should rebuild government finances due to their severe monetary environment. We have already considered the change of the polling place assignment in a Japanese city to increase the voter turnout and to reduce the number of the polling places using regional polling coefficients estimated from a past election result. Using those regional polling coefficients, we changed the polling place assignment using an EMO algorithm. In our previous study, we identified regional polling coefficients from a single election result. In our present study, we identify them by several election results, and analyze the difference of them. In particular, we compare the difference of regional property and results of polling place assignment by employing an EMO Algorithm, and consider the validity of the way of identifying regional polling coefficients.
