class HCL_EvalBigMFcnl_d : public HCL_EvaluateFunctional_d

HCL_EvalBigMFcnl_d is the "evaluation object" for the functional class HCL_BigMFcnl_d, which implements a "big-M" functional for the problem of finding a vector satisfying (that is, the goal is to find a point strictly satisfying )

Inheritance:

Public Methods

	HCL_EvalBigMFcnl_d ( const HCL_GenericProductVector_d & x, HCL_LinearOp_d * AA, HCL_Vector_d * bb, double M, double eps ) Usual constructor; takes (a reference to) the input vector, a pointer to the linear operator, a pointer to the right-hand side vector, and the parameters and
virtual HCL_VectorSpace_d&	Domain () const Domain returns a reference to the domain space.
virtual double	Value () const Value computes the value of the functional.
virtual void	Gradient ( HCL_Vector_d & g ) const Gradient computes the gradient of the functional.
virtual HCL_LinearOp_d*	Hessian () const Hessian computes the Hessian of the functional
virtual ostream&	Write ( ostream & str ) const Write outputs a description of the object.

HCL_EvalBigMFcnl_d( const HCL_GenericProductVector_d & x, HCL_LinearOp_d * AA, HCL_Vector_d * bb, double M, double eps )

Usual constructor; takes (a reference to) the input vector, a pointer to the linear operator, a pointer to the right-hand side vector, and the parameters and

virtual HCL_VectorSpace_d& Domain() const

Domain returns a reference to the domain space.

virtual double Value() const

Value computes the value of the functional.

virtual void Gradient( HCL_Vector_d & g ) const

Gradient computes the gradient of the functional.

virtual HCL_LinearOp_d* Hessian() const

Hessian computes the Hessian of the functional. Note that this method creates an instance of HCL_LinearOp_d, which the calling routine must delete using HCL_delete.

virtual ostream& Write( ostream & str ) const

Write outputs a description of the object.
