A Co-evolution model of Scores and Strategies in IPD games: toward the understanding of the emergence of the social morals

摘要

It was shown that the evolution of a world consisting of agents that play Iterated Prisoner Dilemma (IPD) games each other is open-ended by Lindgren. The behavior of the world is very sensitive to the values of the payoff matrix used in IPD games, because the values have great influence on the population dynamics of the world. In general, the values are fixed throughout the simulations. In the real, the values are fixed through-out the simulations. In the real world, however, morals and the behaviors of individuals that follow the morals have been evolved influencing mutually.
