Method Details

getMaximumValues

public static double[] getMaximumValues(Front front)

Deprecated.

Gets the maximum values for each objectives in a front

Parameters:

front - A front of objective values

Returns:

double [] An array with the maximum values for each objective

getMinimumValues

public static double[] getMinimumValues(Front front)

Deprecated.

Gets the minimum values for each objectives in a given front

Parameters:

front - The front

Returns:

double [] An array with the minimum value for each objective

distanceToNearestPoint

public static double distanceToNearestPoint(Point point,
 Front front)

Deprecated.

Gets the distance between a point and the nearest one in a front. If a distance equals to 0 is found, that means that the point is in the front, so it is excluded

Parameters:

point - The point

front - The front that contains the other points to calculate the distances

Returns:

The minimum distance between the point and the front

distanceToNearestPoint

public static double distanceToNearestPoint(Point point,
 Front front,
 Distance<double[],double[]> distance)

Deprecated.

Gets the distance between a point and the nearest one in a front. If a distance equals to 0 is found, that means that the point is in the front, so it is excluded

Parameters:

point - The point

front - The front that contains the other points to calculate the distances

Returns:

The minimum distance between the point and the front

distanceToClosestPoint

public static double distanceToClosestPoint(Point point,
 Front front)

Deprecated.

Gets the distance between a point and the nearest one in a given front. The Euclidean distance is assumed

Parameters:

point - The point

front - The front that contains the other points to calculate the distances

Returns:

The minimum distance between the point and the front

distanceToClosestPoint

public static double distanceToClosestPoint(Point point,
 Front front,
 Distance<double[],double[]> distance)

Deprecated.

Gets the distance between a point and the nearest one in a given front

Parameters:

point - The point

front - The front that contains the other points to calculate the distances

Returns:

The minimum distance between the point and the front

getInvertedFront

public static Front getInvertedFront(Front front)

Deprecated.

This method receives a normalized pareto front and return the inverted one. This method is for minimization problems

Parameters:

front - The pareto front to inverse

Returns:

The inverted pareto front

convertFrontToArray

public static double[][] convertFrontToArray(Front front)

Deprecated.

Given a front, converts it to an array of double values

Parameters:

front -

Returns:

A front as double[][] array

convertFrontToSolutionList

public static List<PointSolution> convertFrontToSolutionList(Front front)

Deprecated.

Given a front, converts it to a Solution set of PointSolutions

Parameters:

front -

Returns:

A front as a List
