public class InvertedDTLZ1
extends DTLZ1

The Inverted DTLZ1 test problem. This problem was introduced to test reference-point based algorithms since not all reference points lie on or intersect with the inverted Pareto front.

InvertedDTLZ1

public InvertedDTLZ1(int numberOfObjectives)

Constructs an Inverted DTLZ1 test problem with the specified number of objectives.

Parameters:

numberOfObjectives - the number of objectives for this problem

Method Details

evaluate

public void evaluate(Solution solution)

Description copied from interface: Problem

Evaluates the solution, updating the solution's objectives in place. Algorithms must explicitly call this method when appropriate to evaluate new solutions or reevaluate modified solutions.

Specified by:

evaluate in interface Problem

Overrides:

evaluate in class DTLZ1

Parameters:

solution - the solution to be evaluated
