Member Function Documentation

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

Returns pivot column, -1 if none.

Lumbers over all columns - slow The Packed CoinIndexedVector updates has cost updates - for normal LP that is just +-weight where a feasibility changed. It also has reduced cost from last iteration in pivot row Can just do full price if you really want to be slow

Implements ClpPrimalColumnPivot.

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

Just sets model.

Implements ClpPrimalColumnPivot.
