Multi Mode Data Sets

TGZ / ZIP: Compressed archives containing the original instance files. Both formats provide identical content and differ only in compression type.
HRS (Heuristic Solutions): Best known feasible solutions obtained by heuristic methods. These solutions are not guaranteed to be optimal.
LB (Lower Bounds): Proven lower bounds on the optimal objective value, provided to assess solution quality and compute optimality gaps.
OPT (Optimal Solutions): Solutions for which optimality has been formally proven. These files are available only for fully solved instances.
JSON: Summary of each instance set in JSON format.
