Abstract
The purpose of this paper is to show that slightly altruistic individuals can build up the cooperative group. We suppose that the sot of agents having various altruistic dispositions are randomly matching and on each matching the agents play the two person's Prisoner's Dilemma game. According to the analysis of this paper, it is clarified that if the conditions that (1) the incentive of deviation from "mutual Cooperation" is small, (2) agents are similar in altruistic disposition, and (3) the initial value of Cooperation rate is high, are satisfied, the system leads to be stable state where the agents taking Cooperation are in majority.
