Abstract
In this paper, we give an overview of the paper. Specifically, by introducing a random variable with possible values of one vote, we define the Renyi entropy of the random variable. Then we show that the maximization of the Renyi entropy is to minimize the Renyi divergence (directed distance) from the distribution of seats to the distribution of population and vice versa. Moreover, we propose a new measure of the bias of the relaxed divisor method of apportionment.
