Studying Complex Stellar Dynamics Using a Hierarchical Multi-Agent Model

This paper defines a new approach for cosmological simulation based on complex systems theory : a hierarchical multi-agent system is used to study stellar dynamics. At each level of the model, global behavior emerges from agent interactions. The presented model uses physicaly-based laws and agentinteractions to present stellar structures has the result of selforganisation. Nevertheless a strong bond with cosmology is kept by showing the capacity of the model to exibit structures close to thoses of the observable universe.
