Member Function Documentation

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

Assignment operator.

virtual CbcHeuristic* CbcHeuristicPartial::clone ( ) const [virtual]

Clone.

Implements CbcHeuristic.

virtual void CbcHeuristicPartial::generateCpp ( FILE * fp ) [virtual]

Create C++ lines to get to current state.

Reimplemented from CbcHeuristic.

virtual void CbcHeuristicPartial::resetModel ( CbcModel * model ) [virtual]

Resets stuff if model changes.

Implements CbcHeuristic.

virtual void CbcHeuristicPartial::setModel ( CbcModel * model ) [virtual]

update model (This is needed if cliques update matrix etc)

Reimplemented from CbcHeuristic.

virtual int CbcHeuristicPartial::solution	(	double &	objectiveValue,
		double *	newSolution
	)			`[virtual]`

returns 0 if no solution, 1 if valid solution with better objective value than one passed in Sets solution values if good, sets objective value (only if good) This is called after cuts have been added - so can not add cuts

Implements CbcHeuristic.

virtual void CbcHeuristicPartial::validate ( ) [virtual]

Validate model i.e. sets when_ to 0 if necessary (may be NULL).

Reimplemented from CbcHeuristic.

void CbcHeuristicPartial::setFixPriority ( int value ) [inline]

Set priority level.
