INFORMATION INTERACTION AND DIVERSITY COEXISTENCE IN COMPETITIVE SOCIETIES

摘要：

We propose a model for evolutionary game dynamics with three strategies based on Moran process in finite populations. To capture the feature of the evolutionary process, we define two essential variables, namely, global and local fixation probabilities, and analyze their characteristics. We find that a single mutant in finite populations has better chances to invade the population than that in infinite populations, and provide indirectly an explanation of the phenomenon of diversity coexistence in natural world. Moreover, by studying the properties of the random variables represented by the fixation probabilities, we provide another explanation of biodiversity.
