Keep your enemies closer and be loud about it

Under what conditions can cooperation emerge and how can we sustain it? 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...

Impact of Trust in the Spatial and Evolutionary Iterated Prisoner’s Dilemma

The complex dynamics that shape human interactions have been the object of studies for decades. One of the most famous examples to analyse the cooperative or defective nature of people is the Iterated Prisoner’s Dilemma (IPD), a versatile dynamic game which has been shown capable of capturing the emergence of cooperative behaviours in...
