In order to study the phenomenon in detail that income distribution follows Pareto law, we analyze the database of high income companies in Japan. We find a quantitative relation between the average capital of the companies and the Pareto index. The larger the average capital becomes, the smaller the Pareto index becomes. From this relation, we can possibly explain that the Pareto index of comp...

Goals: understand why hypervolume-based search is that successful understand basic properties of hypervolume indicator Approach: rigorous running time analyses of a hypervolume-based MOEA for (i) approaching the Pareto front (ii) approximating large Pareto fronts (unary) hypervolume indicator (A) = hypervolume/area of dominated part of search space between front A and reference point Pareto-dom...
