Pointer<IntervalGradientCut> IntervalGradientCutGenerator::get_cuts	(	const dvector &	x,
		int	k,
		const dvector &	low,
		const dvector &	up
	)

Generate interval gradient cut information according to a solution estimate and a block.

Parameters:

	x	The solution estimate. (reference point)
	k	The block-number.
	low	Current lower bounds.
	up	Current upper bounds.
