Opinion dynamics under different agents´ personality

There are four different agents´ personality, and we introduce them into Deffuant model, one of the models in opinion dynamics, to improve the evolution rules. First, we simulate it under single personality to prove that different types have different effect on opinion evolution. Second, we get the conclusion that it is difficult to achieve agreement among group members with large part of submissive type and stubborn type of agents through a series of simulation experiments under different proportions of the four different types.
