This site contains accompanying material to the papers
by Matteo Fischetti, Ivana Ljubic and Markus Sinnl.
Can be found in the UflLib. Note that some of them have also been used for qUFL.
- ORLIB-format (see here for a format description)
- LP-files of perspective reformulation-10 to 80 facilities
- LP-files of perspective reformulation-100 to 250 facilities
Solutions are in the UflLlib format, i.e., for every customer, the facility it is allocated to is given, and in the end, the solution value is given.
- Heuristic Results for KG-instances g*500/750 (Local Branching Table from the "Redesigning Benders"-paper) Note: Includes also local branching results for the 10 g*500/750 instances, where the optimal solution is known; moreover, for three instances, improved heuristic solutions compared to the ones in the paper are included (obtained a with more aggressive local branching setting).
