The Vehicle Routing Problem with Backhauls (VRPB) is an extension of the VRP that deals with two types of customers: the consumers (linehaul) that request goods from the depot and the suppliers (backhaul) that send goods to the depot. In this paper, we propose a simple yet effective iterated...

Using a structured design methodology, we develop an eXcient iterated local search metaheuristic for the water distribution network design optimisation problem. The algorithm outperforms existing algorithms in the literature while being considerably less complex. Our approach is — contrary to...

We focus on the D-optimal design of screening experiments involving main-effects regression models, especially with large numbers of factors and observations. We propose a new selection strategy for the coordinate-exchange algorithm based on an orthogonality measure of the design. Computational...
