GCG

This classifier adds constraints to classes according to their type given by SCIP. There are different constraint types supported:

• Linear Constraints (linear)
• Knapsack Constraints (knapsack)
• Variable Bounds (varbound)
• Set Packing Constraints (setpacking)
• Set Covering Constraints (setcovering)
• Set Partitioning Constraints (setpartitioning)
• Logical OR Constraints (logicor)
• Special Ordered Set (at most one variable non-zero) (sos1)
• Special Ordered Set (at most two variables non-zero (must be adjacent)) (sos2)
• Unknown Type Constraints (unknown)

Classification

Dantzig-Wolfe and Benders Decomposition

In both modes, the handling is as follows:

• A new class is generated for each of the aforementioned types.
• By default, the class with name newConstype is generated
