CbcLink() [2/4]

CbcLink::CbcLink	(	CbcModel *	model,
		int	numberMembers,
		int	numberLinks,
		int	first,
		const double *	weights,
		int	setNumber )

Useful constructor - A valid solution is if all variables are zero apart from k*numberLink to (k+1)*numberLink-1 where k is 0 through numberInSet-1.

The length of weights array is numberInSet. For this constructor the variables in matrix are the numberInSet*numberLink starting at first. If weights null then 0,1,2..

CbcLink() [3/4]

CbcLink::CbcLink	(	CbcModel *	model,
		int	numberMembers,
		int	numberLinks,
		int	typeSOS,
		const int *	which,
		const double *	weights,
		int	setNumber )

Useful constructor - A valid solution is if all variables are zero apart from k*numberLink to (k+1)*numberLink-1 where k is 0 through numberInSet-1.

The length of weights array is numberInSet. For this constructor the variables are given by list - grouped. If weights null then 0,1,2..
