“…The paper of Martello et al (1997) discusses effective lower bounds for the problem based on Lagrangian relaxation and presents some approximate algorithms. Some efficient heuristic approaches are discussed in Glass et al (1994), Piersma and Van Dijk (1996), Srivastava (1998), Sourd (2001), Mokotoff and Chrétienne (2002), Mokotoff and Jimeno (2002), Ghirardi and Potts (2005), Monien and Woclaw (2006), Guo et al (2007), Fanjul-Peyro and Ruiz (2010), Fanjul-Peyro and Ruiz (2011) and Lin et al (2011). Glass et al (1994) perform a comparison between a genetic algorithm, a simulated annealing approach and a tabu search algorithm.…”
