Study on Rumor Spreading Model Based on Evolution Game

The social mechanisms of rumor fulfilling were focused on based on evolution game.Communication functions between individuals were given by describing pertinence and faintness of rumor.Based on these definitions,an agent simulation model of rumor propagation was realized.Analysis of this model leads to conclusions: Rumors related to people's personal interests win acceptance through changing people's expected payoffs,misleading people to the belief that acceptance of the rumor would beneficially outperform rejection of it.But because it is risky to believe rumors,people make their decision whether to believe a rumor or not by referring to other people's choices.Study on mechanisms of rumor spreading based on evolution game offers innovative research of rumor spreading new means.
