A Recommender System based on the Immune Network (2002)
Presentation / Conference Contribution
Cayzer, S., & Aickelin, U. (2002). A Recommender System based on the Immune Network.

Abstract-The immune system is a complex biological system with a highly distributed, adaptive and self-organising nature. This paper presents an artificial immune system (AIS) that exploits some of these characteristics and is applied to the task of... Read More about A Recommender System based on the Immune Network.

'On the Effects of Idiotypic Interactions for Recommendation Communities in Artificial Immune Systems' (2002)
Presentation / Conference Contribution
Cayzer, S., & Aickelin, U. 'On the Effects of Idiotypic Interactions for Recommendation Communities in Artificial Immune Systems'. Presented at 1st International Conference on Artificial Immune Systems (ICARIS - 2002)

It has previously been shown that a recommender based on immune system idiotypic principles can outperform one based on correlation alone. This paper reports the results of work in progress, where we undertake some investigations into the nature of t...

Knowledge discovery in hyper-heuristic using case-based reasoning on course timetabling (2002)
Presentation / Conference Contribution
Burke, E., MacCarthy, B. L., Petrovic, S., & Qu, R. (2002). Knowledge discovery in hyper-heuristic using case-based reasoning on course timetabling.

This paper presents a new hyper-heuristic method using Case-Based Reasoning (CBR) for solving course timetabling problems. The term Hyper-heuristics has recently been employed to refer to 'heuristics that choose heuristics' rather than heuristics tha...

Prevalence and abundance of Cryptosporidium parvum and Giardia spp. in wild rural rodents from the Mazury Lake District region of Poland (2002)
Journal Article
Bajer, A., Bednarska, M., Pawelczyk, A., Behnke, J. M., Gilbert, F. S., & Sinski, E. (2002). Prevalence and abundance of Cryptosporidium parvum and Giardia spp. in wild rural rodents from the Mazury Lake District region of Poland. Parasitology, 125(1), https://doi.org/10.1017/S0031182002001865

Prevalence and abundance of Cryptosporodium parvum and Giardia spp. were studied in 3 species of rodents from forests and abandoned agricultural fields in N.E. Poland (Clethrionomys glareolus n=459; Microtus arvalis n=274; Apodemus flavicollis n=209)...

Non-Symbolic Fragmentation (2002)
Presentation / Conference Contribution
Ashman, H., Coupe, H., Smith, P., Neville-Smith, M., & Gilbert, M. (2002). Non-Symbolic Fragmentation.

This paper reports on the use of non-symbolic fragmentation of data for securing communications. Non-symbolic fragmentation, or NSF, relies on breaking up data into non-symbolic fragments, which are (usually irregularly-sized) chunks whose boundaries... Read More about Non-Symbolic Fragmentation.

'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....

Partnering Strategies for Fitness Evaluation in a Pyramidal Evolutionary Algorithm (2002)
Presentation / Conference Contribution
Aickelin, U., & Bull, L. Partnering Strategies for Fitness Evaluation in a Pyramidal Evolutionary Algorithm. Presented at Genetic and Evolutionary Computation Conference

This paper combines the idea of a hierarchical distributed genetic algorithm with different inter-agent partnering strategies. Cascading clusters of sub-populations are built from bottom up, with higher-level sub-populations optimising larger parts o...

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...
