Constructor & Destructor Documentation

CbcBranchDecision::CbcBranchDecision ( )

Default Constructor.

CbcBranchDecision::CbcBranchDecision ( const CbcBranchDecision & )

virtual CbcBranchDecision::~CbcBranchDecision ( ) [virtual]

Destructor.

Member Function Documentation

virtual CbcBranchDecision* CbcBranchDecision::clone ( ) const [pure virtual]

Clone.

Implemented in CbcBranchUserDecision, CbcBranchDefaultDecision, and CbcBranchDynamicDecision.

virtual void CbcBranchDecision::initialize ( CbcModel * model ) [pure virtual]

Initialize e.g. before starting to choose a branch at a node.

Implemented in CbcBranchUserDecision, CbcBranchDefaultDecision, and CbcBranchDynamicDecision.

virtual int CbcBranchDecision::betterBranch	(	CbcBranchingObject *	thisOne,
		CbcBranchingObject *	bestSoFar,
		double	changeUp,
		int	numberInfeasibilitiesUp,
		double	changeDown,
		int	numberInfeasibilitiesDown
	)			`[pure virtual]`

Compare two branching objects.

Return nonzero if branching using thisOne is better than branching using bestSoFar.

If bestSoFar is NULL, the routine should return a nonzero value. This routine is used only after strong branching. Either this or bestBranch is used depending which user wants.

Implemented in CbcBranchUserDecision, CbcBranchDefaultDecision, and CbcBranchDynamicDecision.
