objective is to minimize the total distance traveled by all the vehicles. This paper presents a hybrid two-phase algorithm … called sweep algorithm (SW) + ant colony system (ACS) for the classical VRP. At the first stage, the VRP is solved by the SW … ; NP-hard problems ; sweep algorithm ; vehicle routing problem …
