Hi,

Is the benders package provided by CPLEX the same with the conventional Benders implementation? or does it contain some acceleration techniques? For instance, does it consider Pareto optimal cuts? Does it try to add multi cuts?

Can you please clarify what you mean by "Benders package"? CPLEX does not provide any package called "Benders". What CPLEX has is an automated Benders decomposition that is built into the engine.

Sorry for the confusion. I meant the automated Benders.

The separation of Benders cuts in CPLEX has its own acceleration techniques, although not the ones you mention. We have some specific normalization for feasibility cuts and we often use an in-out scheme in the Benders cutloop.

Hi,

Thanks for the answer. If I am only concerned with the optimality cuts, then CPLEX does not apply any sophisticated method on the cuts generated, does it?

Not at the cut generating LP level.
