Well, yes ... it is sort of a mix of the two. We compare the resulting
spatial forms qualitatively to Hawick's clusters. But it is definitely a
predator-prey model, and the oscillations match what you would expect
generally from the Lotka-Volterra equations. (I say generally because of
course an
I'd be careful assuming 2D problems having similarity with 3D problems.
An example Frank can tell you more about is the commutability of
rotations. This works fine in 2D but not in 3D.
In an area I'm more familiar with, polynomial time vs exponential time
algorithms, there is a huge break
I am not sure what you want to model,
perhaps you are mixing different models here?
* predator-prey or Lotka-Volterra equations describe
the long-term population density over multiple generations
* boids and flocking models describe the short-term
spatial form of animal groups on the move
I

It pretty much explains the rapid decline of places like LANL, as well as
the US financial system.
