Simulated Evolution is the umbrella name for a set of projects focused on using agent-based modeling to explore and learn about evolutionary processes.
Emergent system simulations like NetLogo do not model the problem of imperfect information or agent perceptions of their environment; real-world emergence, in contrast, may depend upon it. Structure is determined by the action of agents, but is in turn determinant of the actions of agents.
