Figure 3. — Time average frequency (over 10⁶ generations) of the frequency of cooperation (black line) and the six classes of strategies ( , and rest) plotted as a function of group size n. Parameter values: B_h = 2, C_h = 1, D_p = 2, C_p = 1, T = 30, μ = 0.01, d = 250. Panel specific parameters: C₁ = 1, z = T (a), C₁=1, z = 5 (b), C₁ = 0, z = 5 (c).
