Research
Learning to optimise and make decisions in complex, dynamic systems
Evolutionary Computation for Combinatorial Optimisation
Designing evolutionary and memetic algorithms that find high-quality solutions to hard routing, scheduling and allocation problems — and scaling them to very large instances by decomposition.
Contributions: MAENS and decomposition-based memetic algorithms for arc routing; differential grouping and cooperative co-evolution for large-scale optimisation (IEEE TEVC Outstanding Paper Award).
Genetic Programming for Real-time Optimisation and Decision-Making
Evolving compact, interpretable decision rules with genetic programming that react instantly to dynamic events in factories, vehicle fleets, cloud data centres and traffic networks.
Contributions: GP hyper-heuristics for dynamic scheduling and routing; the first book on the topic; EuroGP and GECCO Best Paper Awards; HUMIES Silver Award.
Machine Learning and Automated Algorithm Design for Optimisation
Using machine learning to make optimisers smarter — learning which operator to apply, where to search, and even how to design the algorithm itself.
Contributions: Adaptive operator selection; learned and neural neighbourhood search for routing; GP-designed algorithm components; IEEE CIM Outstanding Paper Award; EvoStar 2026 Best Student Paper.
Explainable AI
Making AI decisions understandable — by evolving models that are interpretable by design, and by explaining the decisions of black-box models.
Contributions: Survey on explainable AI by GP; local and counterfactual explanations for evolved policies; interpretability-aware GP; GECCO 2022 Best Paper Award; ITNAC 2025 Best Student Paper.
Transfer, Multitask, and Lifelong Machine Learning
Reusing knowledge across related problems so that learning is faster and generalises better — from one task to another, across tasks at once, and over a lifetime of tasks.
Contributions: Knowledge-transfer and multitask GP; lifelong learning for optimiser generation and neural routing solvers (IJCAI 2025, ICLR 2026); EuroGP 2022 Best Paper Award.
