public abstract class PenaltyFunction
extends Object
implements RealScalarFunction

A function P: Rⁿ -> R is a penalty function for a constrained optimization problem if it has these properties.

• P is continuous;
• P(x) >= 0;
• P(x) = 0 if x is feasible; i.e., all constraints are satisfied

dimensionOfRange

public int dimensionOfRange()

Description copied from interface: Function

Get the dimension of the range space of the function. For example, for a Rⁿ->R^m function, the dimension of the range is m.

Specified by:

dimensionOfRange in interface Function<Vector,Double>

Returns:

the dimension of the range
