This paper addresses the unrelated parallel machines scheduling problem with sequence and machine dependent setup times. Its goal is to minimize the makespan. The problem is solved by a combinatorial Benders decomposition. This method can be slow to

The focus of this work is the study of valid inequalities and exact algorithms for the pickup and delivery traveling salesman problem with multiple stacks. In the problem, a single vehicle must fulfill a set of client requests. Each request states th

We consider a problem arising in the design of ad-hoc wireless sensor networks. Given a connected bidirectional digraph with n sensors and a fixed sink, the p-arborescence star problem is the problem of clustering the sensors into p disjoint subsets

The Steiner Team Orienteering Problem (STOP) is defined on a digraph in which arcs are associated with traverse times, and whose vertices are labeled as either mandatory or profitable, being the latter provided with rewards (profits). Given a homogen
