Multi-objective Hierarchic Memetic Solver for Inverse Parametric Problems Authors: Julen Álvarez-Aramberri,Julen Álvarez-Aramberri,Julen Álvarez-Aramberri,Maciej Smołka,Ewa Gajda-Zagórska,David Pardo,David Pardo,David Pardo,Robert Schaefer We propose a multi-objective approach for solving challenging inverse parametric problems. The objectives are misfits for several physical descriptions of a phenomenon under consideration, whereas their domain is a common set of admissible parameters. The resulting Pareto set, or parameters close… Elsevier BV	2015-01-01
