摘      要：Migration is ubiquitous in both biological worlds and human societies for seeking more suitable environments or greater benefits. It may provide an effective mechanism to promote cooperation in the context of spatial prisoner’s dilemma, where agents can either update strategies or adjust positions after participating in a game. On the one hand, agent behavior depends on the tendency to update strategy or change position. On the other hand, agent decision is also influenced by the information it receives about the surroundings. In this work, we propose a co-evolutionary model assuming agents have different tendencies for migration and imitation, and are with different accuracy on the information of imitation and of migration. The simulation results show that the higher accuracy of the information on imitation and migration contributes to a higher cooperation level. In particular, the imitation-oriented mode is more conducive to cooperation when the imitation information accuracy is high. Likewise, the migration-oriented mode is more conducive to cooperation with higher accuracy of the migration information. When imitation and migration information accuracies are both high, cooperation is effectively maintained in two different ways: the imitation-dominant pattern and the migration-dominant pattern, while the scenario in which the imitation tendency is close to the migration tendency has an inhibitory effect on cooperation. © 2023, The Authors.
