Constructor & Destructor Documentation

ClpConstraintAmpl::ClpConstraintAmpl ( )

Default Constructor.

ClpConstraintAmpl::ClpConstraintAmpl	(	int	row,
		void *	amplInfo
	)

Constructor from ampl.

ClpConstraintAmpl::ClpConstraintAmpl ( const ClpConstraintAmpl & rhs )

Destructor.

Member Function Documentation

virtual int ClpConstraintAmpl::gradient	(	const ClpSimplex *	model,
		const double *	solution,
		double *	gradient,
		double &	functionValue,
		double &	offset,
		bool	useScaling = `false`,
		bool	refresh = `true`
	)			const `[virtual]`

Fills gradient.

If Ampl then solution may be NULL, also returns true value of function and offset so we can use x not deltaX in constraint If refresh is false then uses last solution Uses model for scaling Returns non-zero if gradient udefined at current solution

Implements ClpConstraint.

virtual void ClpConstraintAmpl::resize ( int newNumberColumns ) [virtual]

Resize constraint.

Implements ClpConstraint.
