const [virtual]

Clone.

virtual CbcNodeInfo* Bonmin::CbcNlpStrategy::fullNodeInfo	(	CbcModel *	model,
		int	numberRowsAtContinuous
	)		const [virtual]

Return a new Full node information pointer (descendant of CbcFullNodeInfo)

virtual CbcNodeInfo* Bonmin::CbcNlpStrategy::partialNodeInfo	(	CbcModel *	model,
		CbcNodeInfo *	parent,
		CbcNode *	owner,
		int	numberChangedBounds,
		const int *	variables,

After a CbcModel::resolve this can return a status.

-1 no effect 0 treat as optimal 1 as 0 but do not do any more resolves (i.e. no more cuts) 2 treat as infeasible
