27 * @brief improvement heuristic which uses an auxiliary objective instead of the original objective function which
28 * is itself added as a constraint to a sub-SCIP instance. The heuristic was presented by Matteo Fischetti
33 /*---+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8----+----9----+----0----+----1----+----2*/
64 * @note the method can be applied in an iterative way, keeping the same subscip in between. If the @p freesubscip
65 * parameter is set to FALSE, the heuristic will keep the subscip data structures. Always set this parameter
