Cooperation Prevails When Individuals Adjust Their Social Ties

Influence of the Intensity of Selection in the PD for Different Time Scales
Fraction of cooperators at the end as a function of W for different values of β = βe = βa , N =103 and z = 30. As depicted in Figure 3, the dilemma corresponds here to the PD with b/c = 2 (T = 2; S = −1). Decreasing values of β increase the viability of the less fit, which in turn makes it easier for cooperators to wipe out defectors.
