Constructor Details

AbsoluteErrorPenalty

public AbsoluteErrorPenalty(EqualityConstraints constraints,
 double[] weights)

Construct an absolute error penalty function from a collection of equality constraints.

Parameters:

constraints - a collection of equality constraints

weights - the weights assigned to the constraints

AbsoluteErrorPenalty

public AbsoluteErrorPenalty(EqualityConstraints constraints,
 double weight)

Construct an absolute error penalty function from a collection of equality constraints. This assigns the same weight to all constraints.

Parameters:

constraints - a collection of equality constraints

weight - the same weight assigned to all constraints

AbsoluteErrorPenalty

public AbsoluteErrorPenalty(EqualityConstraints constraints)

Construct an absolute error penalty function from a collection of equality constraints. We assign the same default weight to all constraints.

Parameters:

constraints - a collection of equality constraints

Method Details

evaluate

public 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)
