Query: Emergence of diverse collective behaviors from local topological
  perception   We present a dynamical model for generic crowds in 2D in which individual
agents are aware of their local environment -- i.e., neighboring agents and
domain boundary features -- and may seek static target locations. Our model
incorporates features common to many other "active matter" models like
collision avoidance, alignment among agents, and homing toward targets.
However, it is novel in key respects: the model combines topological and
metrical features in a natural manner based upon the local environment of the
agent's Voronoi diagram. With only two parameters, it is shown to capture a
wide range of collective behaviors.
