Retraction based Direct Search Methods for Derivative Free Riemannian Optimization

Vyacheslav Kungurtsev, Francesco Rinaldi, Damiano Zeffiro

Direct search methods represent a robust and reliable class of algorithms for solving black-box optimization problems. In this paper, we explore the application of those strategies…

Stochastic trust-region and direct-search methods: A weak tail bound condition and reduced sample sizing

Francesco Rinaldi, Luis Nunes Vicente, Damiano Zeffiro

Using tail bounds, we introduce a new probabilistic condition for function estimation in stochastic derivative-free optimization which leads to a reduction in the number of samples…
