| Abstract(in English) | Replicator dynamics is a model of changes of shares of strategies in a population which consists of a large number of players. Its extension to multi-population games has been studied. In interactions among multiple populations, a player's payoff depends not only on his/her strategy but also on which populations he/she belongs to. Therefore, migrations of players among populations must be taken consideration. In this paper, we propose multi-population replicator dynamics with player's migration among populations. To compensate payoffs of populations which have different values, we introduce scaling factors which normalize them. Moreover, we consider that dynamics of shares of strategies and that of the migration have different time scales. Therefore, we introduce a time scaling factor into our model. Using some 3-population 3-strategy games, we investigate behaviors of our model. |
