public interface PopulationFitnessVector

An interface to a vector of fitnesses of a population.

Nested Class Summary

Nested Classes

Modifier and Type	Interface	Description
static interface	PopulationFitnessVector.DoubleFitness	An interface to a vector of fitnesses, each a double, of a population.
static interface	PopulationFitnessVector.IntegerFitness	An interface to a vector of fitnesses, each an int, of a population.

Method Summary

Modifier and Type	Method	Description
double	fitnessAsDouble(int i)	The fitness of the a member of the population represented as a double.
int	size()	The size of the population.

Method Details

size

int size()

The size of the population.

Returns:

the size of the population

fitnessAsDouble

double fitnessAsDouble(int i)

The fitness of the a member of the population represented as a double. For implementations of the PopulationFitnessVector.DoubleFitness interface, this is the same as the PopulationFitnessVector.DoubleFitness.fitness(int) method. For implementations of the PopulationFitnessVector.IntegerFitness interface, this method simply returns PopulationFitnessVector.IntegerFitness.fitness(int). This method is provided as a convenience for cases where you cannot exploit integer-valued fitnesses for code optimization. Thus utilizing the fitnessAsDouble method may lead to simplified code.

Parameters:

i - The index into the population, which must be in the interval [0, size()).

Returns:

the fitness of population member i.
