Gradient of selection and equilibria of the N-person Hawk-Dove Game in finite populations. (a) Gradient of selection G(k) in the N-person HDG as a function of the discrete fraction k/Z of doves, for different population sizes Z and a sample size of N = 5. Different shapes of symbols represent different population sizes Z = 10, 20, 100, while solid (resp., empty) symbols represent a cost of c H = 0.1 (resp., 0.5). (b) Equilibria of the N-person Hawk-Dove Game in finite populations for different values of cost c H , and a population size of Z = 100. Symbols denote the required values of c H for which there exists an equilibrium at k/Z. Note that, for finite populations, k/Z takes discrete values. Different symbols represent different sample sizes N. Other parameters are R = 1, w = 1.
