In the capacitated arc routing problem with multiple centers (M-CARP) the objective is to ®nd routes starting from the given depots or centers such that each required arc is served, capacity (and usually additional) constraints are satis®ed and total travel cost is minimized. In this paper we consider a heuristic transformation of the M-CARP into a multiple(More)
