Orizon Pereira Ferreira (Universidade Federal de Goiás) - First order methods for optimization on Riemannian manifolds
Abstract In this presentation we consider optimization problems on Riemannian manifolds and presents asymptotic and iteration-complexity analysis for gradient and subgradient methods on manifolds with sectional curvatures bounded from below. It also establishes asymptotic and iteration-complexity analysis for the proximal point method on Hadamard manifolds.
Ana Luísa Custódio (Nova School of Science and Technology - Portugal) - Ten years of Direct Multisearch
Abstract Direct Multisearch (DMS) is a well-known multiobjective derivative-free optimization class of methods, with competitive computational implementations that are often successfully used for benchmark of new algorithms and in practical applications. As a directional direct search method, its structure is organized in a search step and a poll step, being...
