) | [virtual] |
Selects the next variable to branch on.
Returns true if all the fractional variables can be trivially rounded. Returns false, if there is at least one fractional variable that is not trivially roundable. In this case, the bestColumn returned will not be trivially roundable.
Implements CbcHeuristicDive.
