Trust and Reputation in Diffusion-Based Spatial Repeated Trials of the Prisoners' Dilemma Model

Abstract

Reputation and trust relationships in many real world social models are crucial for capturing detailed interactions between particulating agents. We develop an agent-based model based around the spatial prisoners' dilemma, but with individual agents having a unique identity as well as an ability to diffuse around the model network. Agents start by trusting all other agents they encounter but remember bad past experiences whereby an agent failed to cooperate with them. We illustrate the effects of different amounts of long term memory on the dynanics of the model and establish a number of quantitative metrics to study the model's transitional behaviour at a macroscopic level. We find a critical memory period around which the model undergoes transitional behaviour.
