Abstract

© 2015 Elsevier B.V. All rights reserved. In last two decades, multiobjective optimization has become main stream and various multiobjective evolutionary algorithms (MOEAs) have been suggested in the field evolutionary computing (EC) for solving hard combinatorial and continuous multiobjective optimization. Most of MOEAs employ single evolutionary operators such as crossovers, mutation and selection for population evolution. In this paper, we have suggested a multiobjective evolutionary algorithm based on multimethod (MMTD) with dynamical resources allocation for coping with continuous multi-objective optimization problems (MOPs). The suggested algorithm has employed two well-known population based stochastic algorithms as a constituent algorithms namely MOEA/D and NSGA-II for population evolution based on dynamic resource allocation scheme. We have examined the performance of our proposed MMTD dealing with two different MOPs test suites, the widely used ZDT problems and recently formulated test instances for the special session of MOEAs competition in 2009 IEEE congress on evolutionary computation (CEC'09). The experimental results accomplished by suggested MMTD are more promising than some state-of-the-art MOEAs in terms of inverted generational distance (IGD)-metric values obtained for most test problems.
