Abstract: | We study effects of average degree on cooperation in
the networked prisoner's dilemma game. Typical structures are
considered, including random networks, small-world networks and
scale-free networks. Simulation results show that the average
degree plays a universal role in cooperation occurring on all
these networks, that is the density of cooperators peaks at some
specific values of the average degree. Moreover, we investigated
the average payoff of players through numerical simulations
together with theoretical predictions and found that simulation
results agree with the predictions. Our work may be helpful in
understanding network effects on the evolutionary games. |
