Impacts of conformist on vaccination campaign in complex networks

摘要

In this paper, we explore the evolution of vaccination behavior in the SIR model. Among the participated individuals, a proportion of rho individuals choose conformist-driven updating mechanism to update their strategies, while the rest of 1-rho individuals update strategies with payoff-driven updating mechanism. Our results show that conformists have rare effect on vaccination if the cost is pretty small except the moderate proportion of conformists, where conformists on the boundary play a leading role on epidemic prevention. While for medium values of cost, an excess of conformists conduces to infectious diseases diffusion. (C) 2019 Elsevier B.V. All rights reserved.
