19  * @author Marc Pfetsch
20  *
21  * This heuristic takes a solution from somewhere else via the function SCIPheurPassSolTrySol(). It
22  * then tries to commit this solution. It is mainly used by cons_indicator, which tries to correct a
23  * given solution, but cannot directly submit this solution, because it is a constraint handler and
24  * not a heuristic.
