SUMMARY:Simulation of swarming behavior using anti-Newtonian forces\, 
 Chaos & Complex Systems Seminar\, Vladimir Zhdankin\, UW Department of
  Physics
DESCRIPTION:The emergent behavior of swarming is investigated by using
  computer simulation. Each biological agent can be represented as a pa
 rticle being influenced by forces due to the other agents in the syste
 m. A short-range repulsive force and long-range attractive force resul
 ts in cohesive swarming behavior. However\, more complicated dynamics 
 can occur when two distinct species are defined to interact with diffe
 rent force laws. In order to recreate predator and prey swarming behav
 ior that has been observed in nature\, an "anti-Newtonian" force will 
 be used between the two species\, which violates Newton's Third Law. T
 he resulting dynamics display a lush variety of features\, including c
 haos and emergent behavior. The interesting cases will be demonstrated
  visually through animations that show the simulations unfold.
