Member Function Documentation

virtual int ClpPrimalQuadraticDantzig::pivotColumn	(	CoinIndexedVector *	updates,
		CoinIndexedVector *	spareRow1,
		CoinIndexedVector *	spareRow2,
		CoinIndexedVector *	spareColumn1,
		CoinIndexedVector *	spareColumn2
	)			[virtual]

Returns pivot column, -1 if none.

Lumbers over all columns - slow updateArray has cost updates (also use pivotRow_ from last iteration) Can just do full price if you really want to be slow

Implements ClpPrimalColumnPivot.

virtual void ClpPrimalQuadraticDantzig::saveWeights	(	ClpSimplex *	model,
		int	mode
	)			[inline, virtual]

Just sets model.

Implements ClpPrimalColumnPivot.
