====== Comparative Study of Recent Multimodal Evolutionary Algorithms ======

This page contains complimentary material for the paper Comparative Study of Recent Multimodal Evolutionary Algorithms ((Pighetti, R., Pallez, D., & Precioso, F. (2015, December). "Comparative Study of Recent Multimodal Evolutionary Algorithms". In Computational Intelligence, 2015 IEEE Symposium Series on (pp. 837-844). IEEE. [[https://www.researchgate.net/publication/282869185_Comparative_Study_of_Recent_Multimodal_Evolutionary_Algorithms|Available here]])).
This includes the implementation of PNA-NSGA2 ((S. Bandaru and K. Deb,"A parameterless-niching-assisted bi-objective approach to multimodal optimization", in Evolutionary Computation (CEC), 2013 IEEE Congress on, June 2013, pp. 95–102. [[https://www.researchgate.net/publication/261038299_A_parameterless-niching-assisted_bi-objective_approach_to_multimodal_optimization|Available here]])) (denoted MMNSGAII on the plots), MOBiDE ((A. Basak, S. Das, and K. Tan, "Multimodal optimization using a biobjective differential evolution algorithm enhanced with mean distance based selection", Evolutionary Computation, IEEE Transactions on, vol. 17, no. 5, pp. 666–685, Oct 2013. [[http://dl.acm.org/citation.cfm?id=2719895|Available here]])) and NSGA-II (( K. Deb, A. Pratap, S. Agarwal, and T. Meyarivan, "A fast and elitist multiobjective genetic algorithm: NSGA-II", Trans. Evol. Comp, vol. 6, no. 2, pp. 182–197, Apr. 2002. [[http://dx.doi.org/10.1109/4235.996017|Available here]])) used to obtain the presented results, as well as results obtained for all the functions from the CEC2013 benchmark ((X. Li, A. Engelbrecht, and M. G. Epitropakis, "Benchmark functions for cec’2013 special session and competition on niching methods for multimodal function optimization", Evolutionary Computation and Machine Learning Group, RMIT University, Australia, Tech. Rep., 2013. [[https://github.com/mikeagn/CEC2013|Available here]])).
Implementations were done in JAVA using ECJ library (("A java-based evolutionary computation research system, ecj", [[http://cs.gmu.edu/~eclab/projects/ecj/|Available here]], accessed: 2016-09-19.)).

All the results are computed with a precision of 1e-3.
