This model looks at the effects of a “control” on agent populations. Much like farmers spraying pesticides/herbicides to manage pest populations, the user sets a control management regiment to be used in the patch environment. Agents also evolve an optimum dispersal rate for a given combination of controls.
The model is a modification of one described in The American Naturalist by Poethke et al. (2003). There the author investigates the emergence of optimum dispersal rates for density-dependent and independent local extinction events.
