Multi-level decision-making (MLDM) handles problems that require compromise between
the objectives of two or more interacting entities which are arranged within a hierarchical …

This work presents integer programming techniques to tackle the problem of the
International Nurse Rostering Competition. Starting from a compact and monolithic …

This chapter presents the main concepts of metaheuristic schemes for Wireless Sensor
Networks (WSNs). WSNs are multi-functional, low-cost, and low-power networks and rely on …

We propose algorithms to compute tight lower bounds and high quality upper bounds (UBs)
for the multilevel capacitated minimum spanning tree problem. We first develop a branch …

This work addresses the multi-level capacitated minimum spanning tree (MLCMST)
problem. It consists of finding a minimal cost spanning tree such that the flow to be …

Main components of internet of things such as wireless sensor networks (WSNs) are
generally modeled as graphs. Matching, dominating set, spanning tree, and vertex cover are …

Résumé This work deals with the routing and Wavelength assignment (RWA) in optical
WDM networks independently on the underlying physical topology. We begin with a review …

The telecommunication network design problem is to configure a telecommunication
network of major hardware and their links in order to satisfy traffic demands and flows …

The capacitated minimum spanning tree (CMST) problem is fundamental to the design of
centralized communication networks. In this paper we consider the multi-level capacitated …

Throughout the last several decades there has been remarkable progress within the
Operational Research (OR) field. The amount of progress is particularly significant when …
