Abstract
Extortion strategies, which can let an individual's surplus exceed her opponent's by a fixed percentage, have played an important role in the understanding of the evolution of cooperation in the Prisoner's Dilemma game. In this paper, we combine individuals' extortion ability with their degrees, and study the influence of extortion diversity in the heterogeneous scale-free network. Our investigation shows that, when individuals' extortion factors are negative correlation with their degrees, these extortionate hubs play as catalysts to enhance the emergence of cooperative behavior. However, when the extortion factors are positively correlated with degrees, the effect of hub's catalyst is weaken.
