OsiOldLink::OsiOldLink ( )
OsiOldLink::OsiOldLink ( const OsiSolverInterface solver,
int  numberMembers,
int  numberLinks,

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..

OsiOldLink::OsiOldLink ( const OsiSolverInterface solver,
int  numberMembers,

)

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..
