We introduce the vertex weight into the spatial prisoners’ dilemma game to investigate the evolution of cooperation … the exponential, power-law and uniform ones. Compared with the traditional version, we find that the cooperation level is … markedly enhanced under the weighted square lattice. For most ranges of b, the highest cooperation level can be obtained under …
