The recent advancement of the agent-based modeling and simulation has been revolutionizing the social sciences and other research fields. The agentbased approach enables us to deal with the model that generates macroscopic phenomena by allowing numbers of agents to act at the micro level within the simulation. Therefore, in the social sciences, we can trace and understand the internal mechanisms in society. Since some interesting implications have been derived from the former researches with agent-based approach, expectations are rising in social sciences.
