It * defines the neighborhood by introducing a distance function between the incumbent solution and the optimum of the LP * relaxation. When applied during a branch-and-bound search, it further takes into account how variables change their * values at different nodes of the tree. */ /*---+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8----+----9----+----0----+----1----+----2*/ #ifndef __SCIP_HEUR_DINS_H__ #define __SCIP_HEUR_DINS_H__ #include "scip/def.h" #include "scip/type_retcode.h" #include "scip/type_scip.h" #ifdef __cplusplus extern "C" { #endif /** creates the DINS primal heuristic and includes it in SCIP * * @ingroup PrimalHeuristicIncludes */ SCIP_EXPORT SCIP_RETCODE SCIPincludeHeurDins( SCIP* scip /**< SCIP data structure */ ); #ifdef __cplusplus } #endif #endif
