Unbeatable cooperative strategies under noise

This paper combines the concepts of noise and stability in the iterated prisoner's dilemma. The purpose is to find strategies that score well (have a high cooperation percentage) in a homogeneous noisy environment, but are also robust to invasions. Generally, strategies that perform best under noise are maximally forgiving, however,...

Effects of Group-based Agents on Iterated Prisoner's Dilemma Strategies in Evolving Spatial Environments

The feeling of belongingness, to be a member of a group, is rooted in human evolutionary history. Cooperative behaviour within such groups has since been an important research topic. The evolution of cooperation in the iterated prisoner's dilemma (IPD) has been shown to be an effective tool of simulating and analysing this behaviour. However, it...

Effects of Noise on Cooperation in Harsh Environments

Interactions in the real world are subject to mistakes and miscommunications. The presence of this noise in interactions challenges cooperation, as one party cannot determine whether the other party did not cooperate on purpose. The Prisoner's Dilemma has commonly been used to study mutual cooperation. Strategies like Tit for Tat that do well in...

Possible effects of lost, wrong and delayed information on the evolution of cooperation

This paper investigates possible effects of different information deficiencies on the evolution of cooperation on the basis of the Iterative Prisoner’s Dilemma. To this end, an evolving pool of players repeatedly participates in Round-Robin tournaments. The effect of 5% lost, 5% wrong and 5% delayed information on the amount of games in which...
