Method Detail

isSatisfied

public static boolean isSatisfied(Constraints constraints,
                                  Vector x,
                                  double epsilon)

Check if the constraints are satisfied.

Parameters:

constraints - the constraints

x - the value to evaluate the constraints at

epsilon - a precision parameter: when a number |x| ≤ ε, it is considered 0

Returns:

true if the constraints are satisfied

isSatisfied

public static boolean isSatisfied(Constraints constraints,
                                  Vector x)

Check if the constraints are satisfied.

Parameters:

constraints - the constraints

x - the value to evaluate the constraints at

Returns:

true if the constraints are satisfied

evaluate

public static Vector evaluate(Constraints constraints,
                              Vector x)

Evaluate the constraints.

Parameters:

constraints - the constraints

x - the value to evaluate the constraints at

Returns:

the constraint values
