Replication, Replication and Replication: Some hard lessons from model alignment
This paper explores the extent to which simulation models can be related to other simulation models so that their results, as well as their intended design, are consistent with each other. Expand
Applying a socially inspired technique (tags) to improve cooperation in P2P networks
In this paper, we focus on the problem of maintaining significant levels of cooperation in peer-to-peer (P2P) networks of selfish adaptive peers. Expand
Evolving social rationality for MAS using "tags"
We propose novel tagging mechanisms for the spontaneous self-organization of group level adaptations in populations of autonomous agents that are socially rational even in open systems. Expand
Model-to-Model Analysis
In recent years there has been an explosion of published literature utilising Multi-Agent-Based Simulation (MABS) to study social, biological and artificial systems. Expand

This paper demonstrates the role of group normative reputation in the promotion of an aggression reducing possession norm in an artificial society. Expand
How to cheat BitTorrent and why nobody does
The BitTorrent peer-to-peer file-sharing system attempts to build robustness to free-riding by implementing a tit-for-tat-like strategy. Expand
Cooperation without Memory or Space: Tags, Groups and the Prisoner's Dilemma
We show that the biasing of game interaction towards agents sharing identical tags (arbitrary markings represented as bit strings) is sufficient to produce high levels of cooperation in the single round PD when agents are boundedly rational optimisers. Expand

A selfish re-wiring protocol that can spontaneously self-organize networks into internally specialized groups (or ‘tribes’). Expand
Can Tags Build Working Systems? From MABS to ESOA
We outline new results coming from multi-agent based social simulation (MABS) that harness "tag-based" mechanisms in the production of self-organized behavior in simulation models. Expand
