Abstract

An hybrid method combining two algorithms is proposed for the global optimization of inverted pattern functions encountered in non destructive control by eddy currents. This method performs first the exploration with a Genetic Algorithm, allowing to localize a "promising area" . Then the search is intensified inside that area, through a Nelder-Mead Simplex Search.
