Detailed Description

Define Special Ordered Sets of type 1 and 2.

These do not have to be integer - so do not appear in lists of integers.

which_ points directly to columns of matrix

Constructor & Destructor Documentation

CbcSOS::CbcSOS

(

)

CbcSOS::CbcSOS	(	CbcModel *	model,
		int	numberMembers,
		const int *	which,
		const double *	weights,
		int	identifier,
		int	type = 1
	)

Useful constructor - which are indices and weights are also given.

If null then 0,1,2.. type is SOS type
