In this paper, I analyze the organization of tasks or activities by acollection of agents. I begin by formally defining organized collections androbustly organized collections of agents in the context of a simple model.Within this framework, I demonstrate that organized collections androbustly organized collections exist and equilibria need not beorganized. I then test whether adaptive agents can self-organize inthis environment. I find that simple behavioral rules can lead to nearly organized, fairly robust collections of agents.
