Abstract

Defectors tend to survive in the spatial prisoner’s dilemma. Thus, many studies have sought to keep the cooperator alive. Here, we aimed to enhance the survival of the cooperator by considering the memory length in the spatial prisoner’s dilemma. In the proposed model, all players are assigned a memory length. Based on this memory length, players updated their strategies to those that were harder to choose in the past only when the score of each neighbor with the same strategy was high. This above strategy update rule therefore alleviates a disadvantageous situation for the player. In this paper, we focused on two cases where the cooperators were initially in the minority and observed their evolution over time. The results showed that the model eventually strives to maintain the cooperator population even when it was initially low.
