Detailed Description
Define Special Linked Ordered Sets.
New style
members and weights may be stored in SOS object
This is for y and x*f(y) and z*g(y) etc

Member Function Documentation
| virtual double OsiLink::infeasibility | ( | const OsiBranchingInformation * | info, | |
| int & | whichWay | |||
| ) | const [virtual] |
Infeasibility - large is 0.5.
Reimplemented from OsiSOS.
| virtual double OsiLink::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* OsiLink::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 OsiLink::resetSequenceEtc | ( | int | numberColumns, | |
| const int * | originalColumns | |||
| ) | [virtual] |
Redoes data when sequence numbers change.
Reimplemented from OsiSOS.
| int OsiLink::numberLinks | ( | ) | const [inline] |
Number of links for each member.
Definition at line 621 of file CbcLinked.hpp.
| virtual bool OsiLink::canDoHeuristics | ( | ) | const [inline, virtual] |
Return true if object can take part in normal heuristics.
Reimplemented from OsiSOS.
Definition at line 626 of file CbcLinked.hpp.
| virtual bool OsiLink::boundBranch | ( | ) | const [inline, virtual] |
Return true if branch should only bound variables.
Reimplemented from OsiObject.
