heur_linesearchdiving.h File Reference Detailed DescriptionLP diving heuristic that fixes variables with a large difference to their root solution. Diving heuristic: Iteratively fixes some fractional variable and resolves the LP-relaxation, thereby simulating a depth-first-search in the tree. Line search diving chooses the variable with the greatest difference of its root LP solution and the current LP solution, hence, the variable that developed most. It is fixed to the next integer in the direction it developed. One-level backtracking is applied: If the LP gets infeasible, the last fixing is undone, and the opposite fixing is tried. If this is infeasible, too, the procedure aborts. Definition in file heur_linesearchdiving.h. #include "scip/scip.h"Go to the source code of this file.
