To establish a trust mechanism for multi-agent systems using evolutionary game theory.
Developed Ev-Trust, a strategy-equilibrium model for trust in decentralized environments.
Integrated direct and indirect trust with expected revenue in a dynamic feedback system.
Utilized a decentralized service framework for agent interactions.
Ev-Trust effectively reduced occurrences of deception and misinformation.
Experimental results showed increased agent trustworthiness and collective revenue.
The model demonstrated stability of local evolutionary equilibria.
