	)

Constructor from ampl.

ClpConstraintAmpl::ClpConstraintAmpl ( const ClpConstraintAmpl & rhs )

Copy constructor .

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

virtual void ClpConstraintAmpl::resize ( int newNumberColumns )

virtual

Resize constraint.

virtual void ClpConstraintAmpl::deleteSome	(	int	numberToDelete,
		const int *	which
	)

virtual

Delete columns in constraint.

virtual void ClpConstraintAmpl::reallyScale ( const double * columnScale )

virtual

Scale constraint.

virtual int ClpConstraintAmpl::markNonlinear ( char * which ) const

virtual

Given a zeroed array sets nonampl columns to 1.

Returns number of nonampl columns

virtual int ClpConstraintAmpl::markNonzero ( char * which ) const

virtual

Given a zeroed array sets possible nonzero coefficients to 1.

Returns number of nonzeros

virtual void ClpConstraintAmpl::newXValues ( )

virtual

Say we have new primal solution - so may need to recompute.
