Evolution of Cooperation through Power Law Distributed Conflicts

Figure 5

The number of the cooperators in the equilibrium according to the power law exponent . The dotted line represents, for a value of ranging from 1.5 to 4, how many cooperators out of 1,000 population remain in the end. The results are obtained from an ensemble average of 100,000 Monte Carlo realizations. The solid line illustrates the mean number of the cooperators when the population is structured on a scale-free network. See Section 3.
