Abstract:
In accordance with competition and cooperation among individuals in social networks, a social network model has been designed. Game theory is introduced to simulate the complicated interaction relations among individuals in social networks. Cooperators or defectors interact with their neighbors following the payoff matrix. It can be seen that the cooperative behavior is easy to extinct for too low or too high values of degrees of influence, and the maximum cooperation level is achieved for medium values of degrees of influence. When the reward is fixed, the cooperative behavior can gradually diffuse and build higher reputations. Finally, we verified the existence of the cluster effect based on the MovieLens dataset and analyzed important influences of opinion leaders in netizen groups.
