21
* Crossover is a large neighborhood search improvement heuristic that is inspired by genetic algorithms and requires
22
* more than one feasible solution. For a set of feasible solutions, e.g., the three best found so far, it fixes
23
* variables that take identical values in all of them and solves a corresponding sub-SCIP. See also @ref

* heur_mutation.h
