We present a multi-objective approach to tackle a real-world nurse scheduling problem using an evolutionary algorithm. The aim is to generate a few good quality non-dominated schedules so that the decision-maker can select the most appropriate one. O...

Springer Verlag. https://doi.org/10.1007/978-3-540-79305-2_15

We are interested in the role of restricted mating schemes in the context of evolutionary multi-objective algorithms. In this paper, we propose an adaptive assortative mating scheme that uses similarity in the decision space (genotypic assortative ma...

Towards improving the utilization of university teaching space (2007)
Journal Article
Beyrouthy, C., Burke, E. K., Landa-Silva, D., McCollum, B., McMullan, P., & Parkes, A. J. (2009). Towards improving the utilization of university teaching space. Journal of the Operational Research Society, 60(1), 130-143. https://doi.org/10.1057/palgrave.jors.2602523

There is a perception that teaching space in universities is a rather scarce resource. However, some studies have revealed that in many institutions it is actually chronically under-used. Often, rooms are occupied only half the time, and even when in... Read More about Towards improving the utilization of university teaching space.

Obtaining better non-dominated sets using volume dominance (2007)
Presentation / Conference Contribution
Le, K., & Landa-Silva, D. (2007, September). Obtaining better non-dominated sets using volume dominance. Presented at 2007 IEEE Congress on Evolutionary Computation, CEC 2007, Singapore

An important goal in multiobjective optimisation is to And a good set of non-dominated solutions that is both well-distributed and well-converged. Most multiobjective optimisation algorithms use the conventional Pareto dominance relationship. Over re... Read More about Obtaining better non-dominated sets using volume dominance.

Asynchronous cooperative local search for the office-space-allocation problem (2007)
Journal Article
Landa-Silva, D., & Burke, D. K. (2007). Asynchronous cooperative local search for the office-space-allocation problem. INFORMS Journal on Computing, 19(4), 575-587. https://doi.org/10.1287/ijoc.1060.0200

We investigate cooperative local search to improve upon known results of the office-space-allocation problem in universities and other organizations. A number of entities (e.g., research students, staff, etc.) must be allocated into a set of rooms so... Read More about Asynchronous cooperative local search for the office-space-allocation problem.

The teaching space allocation problem with splitting (2006)
Book Chapter
Beyrouthy, C., Burke, E. K., Landa-Silva, D., Mccollum, B., Mcmullan, P., & Parkes, A. J. (2006). The teaching space allocation problem with splitting. In Practice and Theory of Automated Timetabling: VI 6th International Conference, PATAT 2006 Brno, Czech Republic, August 30–September 1, 2006 Revised Selected Papers (228-247). Springer Verlag. https://doi.org/10.1007/978-3-540-77345-0_15

A standard problem within universities is that of teaching space allocation which can be thought of as the assignment of rooms and times to various teaching activities. The focus is usually on courses that are expected to fit into one room. However,... Read More about The teaching space allocation problem with splitting.

The influence of the fitness evaluation method on the performance of multiobjective search algorithms (2006)
Journal Article
Burke, E. K., & Landa Silva, J. D. (2006). The influence of the fitness evaluation method on the performance of multiobjective search algorithms. European Journal of Operational Research, 169(3), 875-897. https://doi.org/10.1016/j.ejor.2004.08.028

In this paper we are concerned with finding the Pareto optimal front or a good approximation to it. Since non-dominated solutions represent the goal in multiobjective optimisation, the dominance relation is frequently used to establish preference bet...

Multi-objective hyper-heuristic approaches for space allocation and timetabling (2005)
Book Chapter

An important issue in multi-objective optimisation is how to ensure that the obtained non-dominated set covers the Pareto front as widely as possible. A number of techniques (e.g. weight vectors, niching, clustering, cellular structures, etc.) have b...
