Constructor & Destructor Documentation

ClpAmplObjective::ClpAmplObjective ( )

Default Constructor.

ClpAmplObjective::ClpAmplObjective ( void * amplInfo )

Constructor from ampl info.

ClpAmplObjective::ClpAmplObjective ( const ClpAmplObjective & rhs )

Copy constructor .

virtual ClpAmplObjective::~ClpAmplObjective ( )

virtual

Destructor.

Member Function Documentation

virtual double* ClpAmplObjective::gradient	(	const ClpSimplex *	model,
		const double *	solution,
		double &	offset,
		bool	refresh,
		int	includeLinear = `2`
	)

virtual

Returns gradient.

If Ampl then solution may be NULL, also returns an offset (to be added to current one) If refresh is false then uses last solution Uses model for scaling includeLinear 0 - no, 1 as is, 2 as feasible

Implements ClpObjective.

virtual double ClpAmplObjective::reducedGradient	(	ClpSimplex *	model,
		double *	region,
		bool	useFeasibleCosts
	)

virtual

Resize objective.

Returns reduced gradient.Returns an offset (to be added to current one).

Implements ClpObjective.

virtual double ClpAmplObjective::stepLength	(	ClpSimplex *	model,
		const double *	solution,
		const double *	change,
		double	maximumTheta,
		double &	currentObj,
		double &	predictedObj,
		double &	thetaObj
	)

virtual

Returns step length which gives minimum of objective for solution + theta * change vector up to maximum theta.

arrays are numberColumns+numberRows Also sets current objective, predicted and at maximumTheta

Implements ClpObjective.

virtual double ClpAmplObjective::objectiveValue	(	const ClpSimplex *	model,
		const double *	solution
	)		const

virtual

Return objective value (without any ClpModel offset) (model may be NULL)

Implements ClpObjective.

virtual void ClpAmplObjective::resize ( int newNumberColumns )

virtual

Resize objective.

Implements ClpObjective.

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

virtual

Delete columns in objective.

Implements ClpObjective.

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

virtual

Scale objective.

Implements ClpObjective.

virtual int ClpAmplObjective::markNonlinear ( char * which )

virtual

Given a zeroed array sets nonlinear columns to 1.

Returns number of nonlinear columns

Reimplemented from ClpObjective.

virtual void ClpAmplObjective::newXValues ( )

virtual

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

Reimplemented from ClpObjective.

ClpAmplObjective& ClpAmplObjective::operator= ( const ClpAmplObjective & rhs )

Assignment operator.

virtual ClpObjective* ClpAmplObjective::clone ( ) const

virtual

Clone.

Implements ClpObjective.

double* ClpAmplObjective::linearObjective ( ) const

Linear objective.
