文摘

We propose an aspiration-induced dormancy mechanism. Players become dormant if their payoffs are lower than the aspiration level. After a dormant period, individuals continue to play the game with others. There exists an intermediate value of aspiration, leading to the highest cooperation level. The evolution of cooperation is obviously influenced by the dormant period.
