に掲載された論文を加筆修正したもの, We consider the effect of stochastic participation in game on the emergence of cooperation in Demographic Donor-Recipient Game. In usual model setting, players are supposed to play games actually with probability one if they are faced to play games. But sometimes players may want to play games, and sometimes may not. We incorporate this tendency to play games into usual Demographic model by assuming that players play game actually with their inheriting probabilities if they are faced to play games. In Demographic Donor-Recipient game, players are initially randomly distributed in square lattice of cells. In each period, players move locally to random cell in neighbors or globally to random unoccupied cell in the whole lattice, and face to play multiple games against local neighbors or against randomly selected global players. In each game, one player is selected as Donor and the other as Recipient randomly and they play the game actually with the product of two Donor's and Recipient's probabilities of participation. Donor has two moves Cooperate or Defect; Cooperate means Donor pays cost for Recipient to receive benefit. Defect means Donor does nothing. We restrict value of these probabilities to be one of H(igh), L(ow) probability, or one. If wealth (accumulated payoff) of player becomes negative or his age becomes greater than his lifetime, he dies. If his wealth becomes greater than some amount and there is unoccupied cell in neighbors, he has an offspring. We show, by Agent-Based Simulation, that the emergence rate of cooperation is fairy small if initial population contains players who have Low probability of participation if he is a Donor and probability of one if he is a Recipient, but introducing variableness of these probabilities promotes the emergence of cooperation., 17th Czech-Japan Seminar on Data Analysis and Decision Making under Uncertainty, Kitakyushu, September 16-19, 2014},
