Advances in Evolutionary Hyper-Heuristics
Unlocking Adaptive Intelligence for Complex Optimization
This tutorial introduces 'Hyper-Heuristics' (HH), a meta-level search methodology that operates on a space of heuristics rather than directly on the problem search space. It covers various types of HH (selection, generation, constructive, perturbative), discusses generality levels and performance assessment, and explores advanced topics such as automated design, machine learning integration, continuous optimization, explainable AI (XAI), and transfer learning within the context of HH. The goal is to achieve higher levels of generality and reusability in solving complex optimization problems.
Executive Impact: Key Performance Indicators

Case Study: Hybridized Metaheuristics (Hassan & Pillay 2019)
This study uses a selection perturbative hyper-heuristic with a genetic algorithm to explore the heuristic space, where perturbative heuristics are metaheuristics to be hybridized. Applied to aircraft landing and bin packing problems, it produced competitive results with state-of-the-art approaches.
Highlight: Achieved competitive results in real-world problems like aircraft landing.
