..., the enhanced multipoint approximation method (MAM) is used to reduce the original nonlinear optimization problem to a sequence of approximations. Then, the sequential quadratic programing technique is applied to find the continuous solution. Following that, the implementation of discrete capability...

... intermediate designs generated by an optimization algorithm. As has been shown previously[14], these phenomena may severely spoil the Optimization of non-linear structures 77 EC 13,2/3/4 78 accuracy of approximate functions, which are used for the multipoint approximation method[13]. Finite element analyses...
