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..

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..

Member Function Documentation
| OsiOldLink& OsiOldLink::operator= | ( | const OsiOldLink & | rhs | ) |
Assignment operator.
Reimplemented from OsiSOS.
| virtual double OsiOldLink::infeasibility | ( | const OsiBranchingInformation * | info, | |
| int & | whichWay | |||
| ) | const [virtual] |
Infeasibility - large is 0.5.
Reimplemented from OsiSOS.
| virtual double OsiOldLink::feasibleRegion | ( | OsiSolverInterface * | solver, | |
| const OsiBranchingInformation * | info | |||
| ) | const [virtual] |
Set bounds to fix the variable at the current (integer) value.
Given an integer value, set the lower and upper bounds to fix the variable. Returns amount it had to move variable.
Reimplemented from OsiSOS.
| virtual OsiBranchingObject* OsiOldLink::createBranch | ( | OsiSolverInterface * | solver, | |
| const OsiBranchingInformation * | info, | |||
| int | way | |||
| ) | const [virtual] |
Creates a branching object.
The preferred direction is set by way, 0 for down, 1 for up.
Reimplemented from OsiSOS.
| virtual void OsiOldLink::resetSequenceEtc | ( | int | numberColumns, | |
| const int * | originalColumns | |||
| ) | [virtual] |
Redoes data when sequence numbers change.
Reimplemented from OsiSOS.
| int OsiOldLink::numberLinks | ( | ) | const [inline] |
Number of links for each member.
