We build a computer simulation of a multi-agent spatial environment using Prisoner’s Dilemma as the principal agent interaction. We expand the model by allowing agents to remember a fixed number of past defectors and abstain from interacting with them again. Agents will be allowed to communicate by openly announcing remembered defectors,warning nearby agents. This way local reputation of each agent is created. We measure how well our model sustains cooperation and how robust it is against environmental harshness. The conclusion we reach is that local reputation works excellent in sustaining cooperation and punishing defection. The length of agent memory and amount of gossip are not important factors, only the range of gossip has to be greater than the agent movement speed.
