Trust-region algorithms: probabilistic complexity and intrinsic noise with applications to subsampling techniques

Autor: Bellavia, S., Gurioli, G., Morini, B., Toint, Ph. L.

A trust-region algorithm is presented for finding approximate minimizers of smooth unconstrained functions whose values and derivatives are subject to random noise. It is shown that, under suitable probabilistic assumptions, the new method finds (in

Adaptive Regularization Algorithms with Inexact Evaluations for Nonconvex Optimization

Autor: Bellavia, S., Gurioli, G., Morini, B., Toint, Ph. L.

A regularization algorithm using inexact function values and inexact derivatives is proposed and its evaluation complexity analyzed. This algorithm is applicable to unconstrained problems and to problems with inexpensive constraints (that is constrai
