摘要
Given a graph whose arc traversal times vary over time, the Time-Dependent Travelling Salesman Problem consists of finding a Hamiltonian tour of least total duration. In this paper we exploit some properties of the problem and develop a branch-and-bound algorithm which outperforms the state-of-the-art branch-and-cut procedure by Cordeau et al. [5].
