Locally optimal associations between dispersal and exploitation strategy. The frequency of dispersal in cooperators (y) and cheaters (z) evolves, and the frequency of cooperators (n) and cheaters (1-n) evolves. Initial frequencies in numerical studies: y = z = n = 0.5. As for Figure 1 except caption a: k = 1.2, c = 0.1; caption b: k = 10, c = 0.1; caption c: k = 1.2, c = 0.3; caption d: k = 10, c = 0.3.
