A Supervised Parallel Optimisation Framework for Metaheuristic Algorithms

A Supervised Parallel Optimisation (SPO) is presented. The proposed framework couples different optimisation algorithms to solve single-objective optimisation problems. The supervision balances the exploration and exploitation capabilities of the distinct optimisers included, providing a general framework to solve problems with diverse characteristics. In this work, four optimisation algorithms are included in the ensemble: Particle Swarm Optimisation (PSO), Genetic Algorithm (GA), Covariance Matrix Adaption – Evolution Strategy (CMA-ES), and Modified Cuckoo Search (MCS). A path finding problem with numerous local minima is used to demonstrate the advantage of SPO. The effectiveness of the approach is compared with that of stand-alone incidences of the integrated optimisation strategies. The good solution generated by SPO is shown to be generally reproducible, while isolated algorithms, at best, render good solutions only occasionally.
