Constructor Detail

SimpleGeneticAlgorithm

public SimpleGeneticAlgorithm()

Construct a new GeneticAlgorithm.

Method Detail

getPopulationGrowth

public double getPopulationGrowth()

Description copied from class: GeneticAlgorithm

Get the population growth factor.

Specified by:

getPopulationGrowth in class GeneticAlgorithm

Returns:

the factor by which the population size increases with each generation (or decreases if < 1).

evolve

public void evolve()

Description copied from class: GeneticAlgorithm

evolves to the next generation for this population. Parents are selected and will recombine and mutate to produce children genomes who will replace some genomes in this population. This operation is sometimes called breeding.

Specified by:

evolve in class GeneticAlgorithm
