Class DifferentialEvolutionSelection

java.lang.Object

org.uma.jmetal.operator.selection.impl.DifferentialEvolutionSelection

All Implemented Interfaces:

Serializable, Operator<List<DoubleSolution>,List<DoubleSolution>>, SelectionOperator<List<DoubleSolution>,List<DoubleSolution>>

public class DifferentialEvolutionSelection
extends Object
implements SelectionOperator<List<DoubleSolution>,List<DoubleSolution>>

Class implementing the selection operator used in DE: a number of different solutions are returned from a population. The number of solutions is requested in the class constructor (by default, its value is 3), and they must be also different from the one indicated by an index (typically, the current solution being processed by a DE algorithm). This current solution can belong to the returned list if the selectCurrentSolution variable is set to True; in this case, the current solution will be the last one of the returned list.
