public class SumOfPenalties
extends PenaltyFunction

This penalty function sums up the costs from a set of constituent penalty functions. This builds a new composite penalty function from existing simpler ones. It applies to any constrained optimization problems.

Constructor Detail

SumOfPenalties

public SumOfPenalties(PenaltyFunction... penalties)

Construct a sum-of-penalties penalty function from a set of penalty functions. The penalties must have the same dimension.

Parameters:

penalties - the constituent penalty functions

Method Detail

evaluate

public java.lang.Double evaluate(Vector x)

Description copied from interface: Function

Evaluate the function f at x, where x is from the domain.

Parameters:

x - x

Returns:

f(x)

dimensionOfDomain

public int dimensionOfDomain()

Description copied from interface: Function

Get the number of variables the function has. For example, for a univariate function, the domain dimension is 1; for a bivariate function, the domain dimension is 2.

Returns:

the number of variables
