Clone.
Implements CbcBranchDecision.
| virtual void CbcBranchUserDecision::initialize | ( | CbcModel * | model | ) | [virtual] |
Initialize i.e. before start of choosing at a node.
Implements CbcBranchDecision.

Returns nonzero if branching on first object is "better" than on second (if second NULL first wins).
This is only used after strong branching. The initial selection is done by infeasibility() for each CbcObject return code +1 for up branch preferred, -1 for down

| ) | [virtual] |
Compare N branching objects.
Return index of best and sets way of branching in chosen object.
This routine is used only after strong branching. This is reccommended version as it can be more sophisticated
