Trust based cooperative system formation and evolution

Referring to the trust relationship models of social people,the trustworthiness of agents was evaluated by util- izing Bayesian method,and a kind of trust mechanism-based multi-agent cooperation system was presented.By updating the trust-based connection between agents,a robust multi-agent cooperation system was formed.The main properties of the proposed cooperative system were analyzed based on random graph model.Simulations prove that the proposed co- operation model can not only improve the efficiency of cooperation of agents and increase the ratio of successful execu- tion of tasks,but also cluster nodes around the trustworthy nodes which have the strong ability of providing resource and assurance the reliability of cooperative agent selection.
