The aim of this work was to solve the switch-box routing problem to optimality by using a branch-and-price algorithm based on an IP model where variables represent Steiner trees and where the pricing problem becomes the problem of finding a Steiner tree in a graph. In the primal algorithm,...

This work presents a Branch-and-Price algorithm for solving a compressor scheduling problem with applications in oil production. The problem consists in defining a set of compressors to be installed for supplying the gas-lift demand of oil wells while minimizing the associated costs. Owing to the...
