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...

This paper surveys the literature on the optimisation of water distribution network design. The water distribution network design (WDND) optimisation problem entails nding the type and diameter of each pipe in the network so that the total cost of the network is minimised without violating any...

In this paper a number of musical features are extracted from a large music database, which are consequently used to build three composer classification models. The first two models, an if-then ruleset and a decision tree, result in an understanding of the style differences between Bach, Haydn...

We consider a routing problem for ambulances in a disaster response scenario, in which a large number of injured people require medical aid at the same time. The ambulances are used to carry medical personnel and patients. We distinguish two groups of patients: slightly injured people who can be...

In this paper we defi?ne a new problem, the aim of which is to fi?nd a set of k dissimilar alternative solutions for a vehicle routing problem (VRP) on a single instance. ?This problem has several practical applications in the cash-in-transit sector and in the transportation of hazardous...

This paper describes the implementation of an Android application, called FuX1, that can continuously play a stream of newly generated fifth species counterpoint. A variable neighborhood search algorithm is implemented in order to generate the music. This algorithm is a modification of an...

In this paper, we present a new metaheuristic solution procedure for the travelling salesperson problem with hotel selection (TSPHS). We develop a simple but powerful metaheuristic for the TSPHS. On the existing benchmark instances for which an optimal solution is known, it obtains 27 out of 28...

This paper proposes a variant of the well-known capacitated vehicle routing problem that models the problem of routing vehicles in the cash-in-transit industry by introducing a risk constraint. In this problem, which is called the risk-constrained cash-in-transit vehicle routing problem...

Record companies invest billions of dollars in new talent around the globe each year. Gaining insight into what actually makes a hit song would provide tremendous benefits for the music industry. In this research we tackle this question by focussing on the dance hit song classification problem....
