In the paper, two global optimization techniques (Coupled Local Minimizers method and the Differential Evolution Algorithm) are compared in a benchmark problem. The challenge is to find, by FE model updating, the crack locations and widths, the latter being related to the flexural spring stiffness used to model the crack. The effectiveness of the two algorithms to find the set of optimization parameters has been compared by performing a statistical analysis of the optimization results.

Abstract
In the paper, two global optimization techniques (Coupled Local Minimizers method and the Differential Evolution Algorithm) are compared in a benchmark problem. The challenge is to find, by FE model updating, the crack locations and widths, the latter being related to the flexural spring stiffness used to model the crack. The effectiveness of the two algorithms to find the set of optimization parameters has been compared by performing a statistical analysis of the optimization results.File in questo prodotto:
