agents move, we find that cooperation can not only be maintained in such a system but there exists an optimal size of … interaction neighborhood, which can induce the maximum cooperation level. When compared with the case that all agents do not move …, cooperation can even be enhanced by the mobility of individuals, provided that the velocity and the size of neighborhood are not …
