Structural shape optimization using evolution strategiesStructural shape optimization using evolution strategies Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-081999enThe objective of this paper is to investigate the efficiency of combinatorial optimization methods and in particular algorithms based on evolution strategies, when incorporated into shape optimization problems. Evolution strategy algorithms are used either on a stand-alone basis, or combined with a conventional mathematical programming technique. The numerical tests presented demonstrate the computational advantages of the proposed approach which become more pronounced in large-scale optimization problems and/or parallel computing environment. http://creativecommons.org/licenses/by/4.0/Engineering Optimization 431515-540 Papadrakakis, Manolis Yiannis Tsompanakis Lagaros, Nikos D Greek mathematics mathematics greek greek mathematics --Cases, clinical reports, statistics --Statistical data statistics cases clinical reports statistics statistical data
