 * @brief  LNS heuristic that tries to combine several feasible solutions
 * @author Timo Berthold
 *
 * Crossover is a large neighborhood search improvement heuristic that is inspired by genetic algorithms and requires
 * more than one feasible solution. For a set of feasible solutions, e.g., the three best found so far, it fixes
 * variables that take identical values in all of them and solves a corresponding sub-SCIP. See also @ref
 * heur_mutation.h
