Covering problems are well-studied in the domain of Operations Research, and, more specifically, Location Science. When location space is a network, most frequent assumption to consider candidate facility locations, points be covered, or both, finite sets. In this work, we study set-covering problem when both locations and demand continuous on network. This variant has received little attention...

Cutting plane methods play a significant role in modern solvers for tackling mixed-integer programming (MIP) problems. Proper selection of cuts would remove infeasible solutions the early stage, thus largely reducing computational burden without hurting solution accuracy. However, major cut approaches heavily rely on heuristics, which strongly depend specific problem at hand and limit their gen...

We present a generic branch-and-bound algorithm for finding all the Pareto solutions of biobjective mixed-integer linear program. The main contributions are new algorithms obtaining dual bounds at node, checking node fathoming, presolve, and duality gap measurement. Our is predominantly decision space search method because branching performed on variables, akin to single objective problems, alt...
