摘要：Many incentive mechanisms have been proposed to encourage cooperation among agents in autonomous networks, but the altruism attribute of agents is considered very few in such mechanisms. In this paper, we introduce other-regarding preference (ORP) and fitness factor theta into incentive mechanism to more realistically characterize the altruism of agents. In our proposed mechanism, an agent's fitness is composed of its own payoff and its neighbors' payoffs. While making a strategy update, the agent not only considers its own benefits but also its opponents' benefits. The payoffs of its neighbors are proportional to the fitness factor theta. Through mathematical analysis and experiments, we find that adding ORP in a well-mixed population may not change the evolution result, but it may slow the evolution and enable cooperators survive longer in the system. In structured networks, ORP together with the structure of the network can help agents with the same strategy form a cluster, thus promoting cooperation in the system.
