Figure 2. — 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 the number of rounds T of the repeated game. Parameter values: B_h = 2, C_h = 1, D_p = 2, C_p = 1, z = T, μ = 0.01, d = 1, n = 10 000. Panel specific parameters: C₁ = 1 (a), C₁ = 5 (b), using equation (2.1) with a = 100, k = 0.9 (c).
