Method Detail

evaluateIndividual

public void evaluateIndividual(Individual<IntegerChromosome> individual)

Description copied from class: GeneticAlgorithm

Evaluates a single individual. This evaluation of individuals is specifically related to the problem to solve. If the genetic algorithm's body has a Fitness, this method calls Fitness.evaluate(jenes.population.Individual) method, otherwise method requiring an implementation by the sublass.

Overrides:

evaluateIndividual in class GeneticAlgorithm<IntegerChromosome>

Parameters:

individual - the individual to be evaluated

randomizeIndividual

protected void randomizeIndividual(Individual<IntegerChromosome> individual)

Description copied from class: GeneticAlgorithm

Performs an individual randomization. It is invoked by GeneticAlgorithm.randomizePopulation(Population). By default randomization is delegated to the individual. In some problems, it would be useful to control the randomization process of individual. This is especially the case of when there are some constraints on genes in order to make the individual valid.

Overrides:

randomizeIndividual in class GeneticAlgorithm<IntegerChromosome>

Parameters:

individual - the individual to be randomize
