Abstract

Following our previous study (Tanimoto, submitted to Physica A) on how network reciprocity is affected when strategy adaptation speed is slower than gaming speed, we conducted a series of simulations to obtain a deeper insight. In the case of a spatial prisoner s dilemma on a scale-free network with a spatial distribution of the strategy updating time scale, we found that a negative correlation between degree and strategy updating speed brings an extremely large cooperation-enhancing effect. This might be because a cooperative hub agent who is insensitive to strategy adaptation can protect against defection invasion at the initial stage of a simulation episode to initiate a cooperative situation.
