    "abstract": "To our knowledge, the populations are generally assumed to be homogeneous in\nthe traditional approach to evolutionary game dynamics. Here, we focus on the\ninhomogeneous populations. A simple model which can describe the inhomogeneity\nof the populations and a microscopic process which is similar to Moran Process\nare presented. By studying the replicator dynamics, it is shown that this model\nalso keeps the fixed points unchanged and can affect the speed of converging to\nthe equilibrium state. The fixation probability and the fixation time of this\nmodel are computed and discussed. In the inhomogeneous populations, there are\ndifferent situations that characterize the time scale of evolution; and in each\nsituation, there exists an optimum solution for the time to the equilibrium\npoints, respectively. Moreover, these results on the speed of evolution are\nvalid for infinite and finite populations.",
