                         identify the damage in a multi-DOF dynamical system composed of 
                         masses, springs, and dampers. The damage is introduced 
                         artificially by choosing a lower value for the stiffness. The 
                         applied algorithms include Nelder-Mead Simplex, BFGS Quasi-Newton, 
                         interior point, and sequential quadratic programming - SQP. In 
                         addition, some different strategies to identify damage are 
                         applied. First, a deterministic analysis is performed to identify 
                         the damage; i.e, the values of the stiffnesses. Then, random 
                         forces are considered, and finally, the stiffness values are 
                         considered uncertain and the different strategies are compared.",
