Detailed Description
Define a follow on class.
The idea of this is that in air-crew scheduling problems crew may fly in on flight A and out on flight B or on some other flight. A useful branch is one which on one side fixes all which go out on flight B to 0, while the other branch fixes all those that do NOT go out on flight B to 0.
This branching rule should be in addition to normal rules and have a high priority.

Member Function Documentation
| CbcFollowOn& CbcFollowOn::operator= | ( | const CbcFollowOn & | rhs | ) |
Assignment operator.
Reimplemented from CbcObject.
| virtual double CbcFollowOn::infeasibility | ( | int & | preferredWay | ) | const [virtual] |
Infeasibility - large is 0.5.
Implements CbcObject.
| virtual void CbcFollowOn::feasibleRegion | ( | ) | [virtual] |
This looks at solution and sets bounds to contain solution.
Implements CbcObject.
| virtual CbcBranchingObject* CbcFollowOn::createBranch | ( | int | way | ) | [virtual] |
Creates a branching object.
Implements CbcObject.
| virtual int CbcFollowOn::gutsOfFollowOn | ( | int & | otherRow, | |
