Abstract:	In examining collective behavior, we focus on the interactions of individuals. We also need to describe on two different levels: the microscopic level, where the decisions of the individual agents occur, and the macroscopic level where collective behavior can be observed. What makes collective behavior is interesting and difficult is that the aggregate outcome is what has to be evaluated within the constraints of the environment. The performance of the collective system depends crucially on the type of interaction as well as the heterogeneity in preference of agents. In this study, for emergence of diversity, we found that it is needed two different speed learning processes. And it is needed isolated interaction for emergence of diversity. But, the utility of less clustered interaction is more than that of isolated interaction if possible. On the whole, we found that isolated interacting is effective for emergence of diversity. Then, once diversity is emerged enough, less clustered interaction is effective to utility of each agent and whole population.
