evaluateIndividual

protected 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, thus it is an abstract method requiring an implementation by the sublass.

Specified by:

evaluateIndividual in class GeneticAlgorithm<IntegerChromosome>

Parameters:

individual - the individual to be evaluated

end

protected boolean end()

Description copied from class: GeneticAlgorithm

Provides the algorithm termination condition. By default it returns false as reaching the generation limit is the sole ending criterion Subclasses can override this method in order to provide a problem specific termination condition.

Overrides:

end in class GeneticAlgorithm<IntegerChromosome>

Returns:

true if the ga evolution reached the termination condition, false otherwise
