Matheuristics: A Primer with Applications in Transportation and Logistics

Matheuristics are heuristic algorithms made by the interoperation of metaheuristics and mathematical programming (MP) techniques. That is, we are concerned with works that are, e.g., exploiting mathematical programming techniques in (meta)heuristic frameworks or with granting to mathematical programming approaches the cross-problem robustness and constrained CPU-time effectiveness which characterize metaheuristics. Popular matheuristics include POPMUSIC as well as generalized local branching. Common features use local search based candidate solutions by means of a fully-fledged optimization method generating optimal solutions over appropriately designed neighborhoods. That is, neighborhoods are constructed to be suitable domains for the optimization method used. We clarify differences and commonalities of these methods and exemplify by problems in transportation and logistics, and especially transportation network design and in maritime shipping.
