| - | This optimization program allows the identification of the values of parameters likely to minimize an objective function representing the difference between two curves. The program will take a reference curve as an input (an experimental curve for instance) and will attempt to approach this curve with the finite element code Lagamine using different parameters obtained through the **Levenberg-Marquardt** algorithm. A schematic representation of th algorithm is shown in <imgref image1>. \\ \\ | + | This optimization program allows the identification of the values of parameters likely to minimize an objective function representing the difference between two curves.
