Multilevel Objective-Function-Free Optimization with an Application to Neural Networks Training

S. Gratton, A. Kopanicakova, Ph. L. Toint

A class of multi-level algorithms for unconstrained nonlinear optimization is presented which does not require the evaluation of the objective function. The class contains the mome…
