Constructor Details

ZCAT20

public ZCAT20(int numberOfObjectives)

Constructs the ZCAT20 test problem.

Parameters:

numberOfObjectives - the number of objectives

ZCAT20

public ZCAT20(int numberOfObjectives,
 boolean complicatedPS)

Constructs the ZCAT20 test problem.

Parameters:

numberOfObjectives - the number of objectives

complicatedPS - true if using the complicated Pareto set shape function; false otherwise

Method Details

getDimension

public int getDimension(double[] y)

Description copied from class: ZCAT

The dimension of the Pareto front / Pareto set. This is typically numberOfObjectives-1 but can differ for certain degenerate (ZCAT14 - ZCAT16) or hybrid (ZCAT19 - ZCAT20) problems.

Overrides:

getDimension in class ZCAT

Parameters:

y - the normalized decision variables

Returns:

the dimension of the Pareto front / Pareto set
