Iterated prisoner's dilemma game with multi-Agent based on evidence theory

Cooperation behavior in multi-Agent systems is studied by using evidence theory and iterated prisoner's dilemma games.To strengthen the cooperation between Agents,this paper constructed a combined trust model using the belief structure.The combined trust was composed of the direct trust based on the direct evidence and the recommended trust based on other Agents' recommended evidence.Based on the constructed model,a combined trust strategy and a game algorithm in iterated prisoner's dilemma game were presented.At last,an application case was simulated in a multi-Agent system.The simulation results demonstrate that the proposed strategy can effectively strengthen the cooperation behavior and increase the revenues of the system.
