Models considered for the initial competition, winner of competition, and time-to-resolution of competition analyses.

dN/dt is the focal species' rate of population
change; dE/dt is the rate of environmental change;
n is the size of the competitor's gene
network; sf is the topology (e.g.,
scale-free) of the
competitor's network; μ is the competitor's mutation
rate; r is the competitor's recombination
rate; and these abbreviations are combined for brevity in some model
descriptions.
