Strategy abundance in games for arbitrary mutation rates

Abstract: We study evolutionary game dynamics in a well-mixed populations of finite size, N. A well-mixed population means that any two individuals are equally likely to interact. In particular we consider the average abundances of two strategies, A and B, under mutation and selection. The game dynamical interaction between the two strategies is given by the 2 × 2 payoff matrix . It has previously been shown that A is more abundant than B, if a(N − 2) + bN > cN + d(N − 2). This result has been derived for particular sto… Show more

“…Nevertheless, in evolutionary and ecological situations there is not only the reproductive rate but also the carrying capacity [21]. The density-dependent dynamic system became a very important direction in evolutionary research [1,2,4]. In order to combine the payoff matrix with competitive Lotka-Volterra equations, Sebastian presented the density game [21].…”

“…Stationary distributions for the Moran process in two dimensions and some recently-studied generalizations are given in several recent works [1,36,[46][47][48][49][50]; stationary distributions for both the Moran process and the Wright-Fisher process have been studied in [51]; a number of formulas for various finite population processes are given in [52] and [53]. The n = 2 solution only relies on the fact that the transition matrix is tridiagonal, and so applies to the incentive process with mutation without modification.…”

“…Some of the corresponding methods require weak selection or rare mutations. But analytical results are also available when selection is strong [14], mutation rates are arbitrary [15,16], or when more than two players are involved in any particular interaction [17,18]. Even the evolution in continuous strategy spaces can be captured with simple differential equations, using the framework of adaptive dynamics in infinite [19] or finite populations [20].…”
