“…Among the resolution methods proposed by the participants of the challenge, one finds essentially neighbourhood search methods as simulated annealing, iterative tabu search, iterative local search and variable neighbourhood search (Briant et al, 2007;Cordeau et al, 2007;Estellon et al, 2007;Ribiero et al, 2007a;Gavranović, 2007;Benoist, 2007), an ant colony optimization algorithm (ACO) and a genetic algorithm (GA) (Jaszkiewicz et al, 2004). Since the work of all the participating teams was not published, the previous enumeration is not exhaustive.…”
