A Branch‐and‐Price Algorithm for the Symmetric Electric Traveling Salesman Problem

Networks, EarlyView.
ABSTRACT The Electric Traveling Salesman Problem (ETSP) is a variant of the well‐known TSP in which an electric vehicle must visit a set of customers minimizing the total cost of its route. The vehicle is assumed to be equipped with a battery of limited capacity that may need to be recharged along the route.
