    Source: Operations Research Letters
    DOI: 10.1016/j.orl.2019.11.005

The asymmetric vehicle routing problem with simultaneous pickup and deliveries is considered. This paper develops four new classes of valid inequalities for the problem. We generalize the idea of a no-good cut. Together, these help us solve 45-node randomly generated problem instances more efficient...(Read Full Abstract)
