A hyper-matheuristic approach for solving mixed integer linear optimization models in the context of data envelopment analysis [PDF]
Mixed Integer Linear Programs (MILPs) are usually NP-hard mathematical programming problems, which present difficulties to obtain optimal solutions in a reasonable time for large scale models.

Two hybrid flow shop scheduling lines with assembly stage and compatibility constraints. [PDF]
Two hybrid flow shop scheduling lines must be coordinated to assemble batches of terminated products at their last stage. Each product is thus composed of two jobs, each produced in one of the lines.

A hybrid VNS matheuristic for a bin packing problem with a color constraint [PDF]
We study a new variant of the bin packing problem with a color constraint. Given a finite set of items, each item has a set of colors. Each bin has a color capacity, the total number of colors for a bin is the unification of colors for its items and ...

A Matheuristic Algorithm for the Multiple-Depot Vehicle and Crew Scheduling Problem
This work addresses the multiple-depot vehicle and crew scheduling problem (MDVCSP). In MDVCSP, we deal with two NP-hard problems in an integrated way: the multiple-depot vehicle scheduling problem (MDVSP) and the crew scheduling problem (CSP).
