Model for the spread of SIS epidemic based on evolution game.

First, a replicated dynamic equation for the spread of an SIS epidemic was proposed using the game theory. It was concluded that evolutionary stable strategies of an epidemic are (Z, C). Based on the method of multi-agent simulation by swarm 2.2, an evolutionary game model was developed to simulate the spread of an epidemic among individuals. It analyzed detailed information of the evolution and the game relationship between individuals in a micro perspective. The final simulation results were consistent with the conclusion of the replicated dynamic equation.
