Assessing hyper-heuristic performance (2020)
Journal Article
Pillay, N., & Qu, R. (2021). Assessing hyper-heuristic performance. Journal of the Operational Research Society, 72(11), 2503-2516. https://doi.org/10.1080/01605682.2020.1796538

Limited attention has been paid to assessing the generality performance of hyper-heuristics. The performance of hyper-heuristics has been predominately assessed in terms of optimality which is not ideal as the aim of hyper-heuristics is not to be com...

Information Retrieval for Evidence-Based Policy Making Applied to Lifelong Learning (2019)
Presentation / Conference Contribution
Clos, J., Qu, R., & Atkin, J. (2019, December). Information Retrieval for Evidence-Based Policy Making Applied to Lifelong Learning. Presented at International Conference on Innovative Techniques and Applications of Artificial Intelligence (SGAI 2019: Artificial Intelligence XXXVI), Cambridge, UK

© 2019, Springer Nature Switzerland AG. Policy making involves an extensive research phase during which existing policies which are similar to the one under development need to be retrieved and analysed. This phase is time-consuming for the following... Read More about Information Retrieval for Evidence-Based Policy Making Applied to Lifelong Learning.
