Field Summary

long	evaluations How many evaluations have we run so far?
protected boolean	firstTime First time calling evolve
boolean	generationBoundary Did we just start a new generation?
int	generationSize how big is a generation? Set to the size of subpopulation 0 of the initial population.
long	numEvaluations How many evaluations should we run for? If set to UNDEFINED (0), we run for the number of generations instead.
static java.lang.String	P_NUMEVALUATIONS
static java.lang.String	P_STEADYSTATE base parameter for steady-state
