Evolutionary Dynamics of Public Goods Game Based on Set Structured Populations

摘要

Population structure takes a deep impact on evolutionary dynamics. The evolutionary process of a well-mixed population can be very different from that of a structured population. This paper refers to an evolution model of set structured populations. In this model, both individuals' strategies and population structure are subject to evolutionary updating. We specially focus on the evolution of cooperative behavior and study the dynamics of evolutionary public goods game in set structured populations. Some key parameters affecting the population's evolution and various dynamic nature showed during the process of evolution are studied by approaches combining theoretical analysis and computer simulations. We found that the co-evolution of both strategies and sets structure can promote cooperation in public goods game. The model advised by us also can be extended and provide new research ideas for more other evolutionary multiplayer game.
