Carlos Segura, Alejandro Cervantes, Antonio J. Nebro, María Dolores Jaraíz-Simón, Eduardo Segredo, Sandra García, Francisco Luna, Juan Antonio Gómez-Pulido, Gara Miranda, Cristóbal Luque, Enrique Alba, Miguel Ángel Vega-Rodríguez (+2 others)
2009 Lecture Notes in Computer Science  
The cooperation of a team of multi-objective evolutionary algorithms has been performed with a novel optimization model.  ...  Such model is a hybrid parallel algorithm that combines a parallel islandbased scheme with a hyperheuristic approach.  ...  The model is based on the hybridization of parallel islandbased evolutionary algorithms and hyperheuristics.  ...

Multi‐Objective Hyper‐Heuristics [chapter]

Mashael Suliaman Maashi
2017 Heuristics and Hyper-Heuristics - Principles and Applications  
Some design issues related to the development of hyper-heuristic framework for multi-objective optimization are discussed.  ...  Work on hyper-heuristics for multi-objective optimization remains limited.  ...  Nevertheless, upcoming efforts are still necessary in advancing the approach. In Ref. [36] , a hypervolume-based hyper-heuristic for a dynamic-mapped multi-objective island-based model is proposed.  ...

Recent Advances in Selection Hyper-heuristics

John H. Drake, Ahmed Kheiri, Ender Özcan, Edmund K. Burke
2019 European Journal of Operational Research  
Hyper-heuristics have emerged as a way to raise the level of generality of search techniques for computational search problems.  ...  The current state-of-the-art in hyper-heuristic research comprises a set of methods that are broadly concerned with intelligently selecting or generating a suitable heuristic for a given situation.  ...  Acknowledgments This work has been partially funded by the DAASE project, EPSRC programme grant EP/J017515/1 and the OR-MASTER project, EPSRC programme grant EP/M020258/1 .  ...

Lost in Optimisation of Water Distribution Systems? A Literature Review of System Design

Helena Mala-Jetmarova, Nargiz Sultanova, Dragan Savic
2018 Water  
Optimisation of WDS design has also progressed from a cost-driven single-objective framework to multi-objective models, when various objectives that continually gain importance (e.g., environmental objectives  ...  To generate multi-objective optimal solutions, those studies use mainly metaheuristics or hyperheuristics, such as structured messy GA (SMGA) [63], NSGA-II [95], non-dominated sorting evolution strategy  ...  time and improve the quality of solutions obtained. • Two parallel models, global and island, are used.  ...
