Enhancements of the Harris Hawks Optimisation Algorithm for Multi-Objective Optimisation

This research presents a nature-inspired metaheuristic algorithm, Harris' Hawk Optimiser (HHO), which is further enhanced to form two multi-objective optimisation models. These models, i.e. four MO-HHO variants and an ensemble of MO-HHO variants (EMO-HHO), are evaluated with a series of multi-objective benchmark functions, and a maintenance scheduling case study is employed to assess the effectiveness of solving real-world problems.<p></p>
