		void *	amplInfo
	)

Constructor from ampl.

ClpConstraintAmpl::ClpConstraintAmpl

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.

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

virtual

Delete columns in constraint.

Implements ClpConstraint.

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

virtual

Scale constraint.

Implements ClpConstraint.

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

virtual

Given a zeroed array sets nonampl columns to 1.

Returns number of nonampl columns

Implements ClpConstraint.

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

virtual

Given a zeroed array sets possible nonzero coefficients to 1.

Returns number of nonzeros

Implements ClpConstraint.

virtual void ClpConstraintAmpl::newXValues ( )

virtual

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

Reimplemented from ClpConstraint.

ClpConstraintAmpl& ClpConstraintAmpl::operator=

(

const ClpConstraintAmpl &

rhs

)

Assignment operator.

virtual ClpConstraint* ClpConstraintAmpl::clone ( ) const

virtual

Clone.

Implements ClpConstraint.

virtual int ClpConstraintAmpl::numberCoefficients ( ) const

virtual

Number of coefficients.

Implements ClpConstraint.

const int* ClpConstraintAmpl::column ( ) const

inline

Columns.

Definition at line 80 of file ClpConstraintAmpl.hpp.

const double* ClpConstraintAmpl::coefficient ( ) const

inline

Coefficients.
