The Countdown Problem (2002)
Journal Article
Hutton, G. (2002). The Countdown Problem. Journal of Functional Programming, 12(6),

We systematically develop a functional program that solves the countdown problem, a numbers game in which the aim is to construct arithmetic expressions satisfying certain constraints. Starting from a formal specification of the problem, we present... Read More about The Countdown Problem.

An indirect genetic algorithm for set covering problems (2002)
Journal Article
Aickelin, U. (2002). An indirect genetic algorithm for set covering problems. Journal of the Operational Research Society, 53(10), 1118-1126. https://doi.org/10.1057/palgrave.jors.2601317

This paper presents a new type of genetic algorithm for the set covering problem. It differs from previous evolutionary approaches first because it is an indirect algorithm, i.e. the actual solutions are found by an external decoder function. The gen...

'Enhanced Direct and Indirect Genetic Algorithm Approaches for a Mall Layout and Tenant Selection Problem' (2002)
Journal Article
Aickelin, U., & Dowsland, K. (2002). 'Enhanced Direct and Indirect Genetic Algorithm Approaches for a Mall Layout and Tenant Selection Problem'. Journal of Heuristics, 8(5), https://doi.org/10.1023/A%3A1016536623961

During our earlier research, it was recognised that in order to be successful with an indirect genetic algorithm approach using a decoder, the decoder has to strike a balance between being an optimiser in its own right and finding feasible solutions....
