heur_rens.h File Reference Detailed DescriptionLNS heuristic that finds the optimal rounding to a given point. RENS is a large neighborhood search start heuristic, i.e., unlike other LNS heuristics, it does not need a known feasible solution. It solves a sub-SCIP that is created by fixing variables which take an integral value in a given LP or NLP solution. For the remaining integer variables, the bounds get tightened to the two nearest integral values. Definition in file heur_rens.h. #include "scip/scip.h" Go to the source code of this file.
