Field Detail

population

protected java.util.Collection population

Data structure holding the individuals of this population. This collection may be used in subclasses, but need not. In case another model is used a user must ensure that all necessary methods are overloaded correctly. Beyond this a new individual iterator must be written.

generation

protected int generation

Generation counter. This counter contains the current generation number. The counter is incremented everytime the insert(IIndividualSet) method is called.

filter

protected IInsertionFilter filter

Individual filter for insertion of individuals into this population.

Constructor Detail

AbstractPopulation

public AbstractPopulation()

Constructor.
