      org.evolvica.core.population.EliteInsertion

All Implemented Interfaces:

IInsertionFilter

Direct Known Subclasses:

ElitistInsertion

public class EliteInsertion

extends AbstractInsertionFilter

Elite reinsertion. According to the value of generationGap the worst individuals will be discarded and replaced by the best individuals of the insertion pool according to the value of insertionRate. With respective values a growing or downsizing population can be set up.
