Abstract for
"Emergent segregation and over-mixing from symmetric movement rules"

In complex systems the interactions of multiple agents with one another and their environment can generate system-level patterns that are quite surprising even when the behavior of the individual agents is simple and well understood. Here we present a paradigmatic example of such a system involving segregation and mixing in a heterogeneous population of agents This model is of interest for several reasons: 1) there is a striking incongruity between the symmetry of the agents’ rules of motion and the asymmetry of the emergent system-level patterns, 2) the cuasal connection s between the local rules and the emergent system-level patterns are understood in unusual detail, and 3) the emergence of segregation and mixing exemplified by this model have important implications in both the biological and social sciences.
