| description | Strategy updates play an important role in the evolution of cooperation. In traditional imitation rules, it is assumed that strategic learning is driven by payoff bias. In this study, a modified Fermi rule was proposed, in which payoff and success-rate are synthetically considered to determine players’ strategy updates. It is assumed that individuals have an immediate memory length M , and that success can be measured by using an identical aspiration level a as a benchmark. Success-rate is defined in the frequency that an individual’s payoff equals or exceeds the benchmark a within the memory length M . Numerical simulations conducted by considering the two factors in the strategy update show that cooperation can be facilitated compared to the traditional version. Using the identical aspiration level a as benchmark, the results show that there is a clear phase shift phenomenon in enhancing cooperation. This implies that different b will have an appropriate aspiration interval to achieve optimal cooperation. Moreover, only a moderate immediate memory length can facilitate cooperation. The proposed mechanism is highly robust and can provide valuable insights into the emergence and maintenance of cooperation. |
