Heterogeneity and Environmental Preferences Shape the Evolution of Cooperation in Supply Networks

Figure 12

Characteristic snapshot of cooperators (yellow) and defectors (blue) for different values of the parameters u and . (a) The traditional type (u = 0 and = 0), (b) the coexistence of environmental heterogeneity and preference (u = 0.2 and  = 1), and (c) the more considerable heterogeneity of environment and environmental preference (u = 0.7 and  = 4). From left to right, the simulation steps are 0, 5, 50, and 500. The depicted are obtained for b = 1.3.
