Constructor & Destructor Documentation

ClpConstraintAmpl::ClpConstraintAmpl (  ) 

Default Constructor.

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

Constructor from ampl.

ClpConstraintAmpl::ClpConstraintAmpl ( const ClpConstraintAmpl rhs  ) 

Copy constructor .

virtual ClpConstraintAmpl::~ClpConstraintAmpl (  )  [virtual]

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]
