Figure 4. Same as Fig. 3 describing Vilanterol trifenatate results for the behavioural equilibrium under the average Prisoner's Dilemma but now for the average Hawk–Dove game. (a, b, c) TR initially prefers Hawk (pTR,1 = 0.15) and HR prefers Dove (pHR,1 = 0.85). (d, e, f) TR initially prefers Dove (pTR,1 = 0.85) and HR prefers Hawk (pHR,1 = 0.15).
