Abstract

We propose a novel idea for the so-called pairwise-Fermi process by considering copy-resistance when an agent copies a neighbor's strategy, which implies that the focal agent with relatively affluent payoff vis-à-vis social average might be negative to copy her neighbor's strategy even if her payoff is less than the neighbor's payoff. Simulation results reveal that this idea with a revised strategy adaptation process significantly enhances cooperation for prisoner's dilemma games played on time-constant networks.
