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.

evaluate
public Double evaluate(Vector x)
Description copied from interface:FunctionEvaluate 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:FunctionGet 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
