public abstract class ArrayPreselection<R extends java.io.Serializable,T extends Solution<io.vavr.collection.Array<R>>>
extends java.lang.Object
implements Preselection<T>

Abstract Preselection implementation. Relies on subclasses to provide the indices of the preselected solution (note that any solution may be chosen multiple times).

Method Detail

preselect

public final io.vavr.collection.List<T> preselect(io.vavr.collection.List<T> population)

Specified by:

preselect in interface Preselection<T extends Solution<io.vavr.collection.Array<R>>>

preselectIndices

protected abstract int[] preselectIndices(double[] values)

Performs the actual preselection. Given an array of evaluation values, returns an array containing indices of the preselected solutions. Any given solution may be preselected multiple times, in which case it will be copied in the resulting preselected population.

Parameters:

values - The solutions evaluation values

Returns:

The indices of the preselected solutions

isMemoized

public boolean isMemoized()
