We consider algorithms for solving\nboth convex and non-convex minimization problems, as well as more general min-max and variational\ninequalities problems. Our speakers will present their works covering a broad spectrum of applications\nincluding safe learning, derivative-free optimization, second-order optimization, and also adaptive,\nstochastic, and decentralized learning<br>\n\n<strong>Mini symposium organizers:<\/strong><br>\nNikita Doikov (\u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne)<br>\nGeovani Nunes Grapiglia (Universit\u00e9 Catholique de Louvain)<br>\n<\/p>\n<p>\n<strong>Session 3.
