Abstract: Black-box optimization problems arise frequently in real-world applications. In these problems, the function values are provided by black-boxes (typically simulations or experiments), and there is no access to derivatives. They have stimulated optimization methods that do not use derivatives, which are commonly referred to as derivative-free optimization methods. This mini-symposium intends to present the latest advances on black-box and derivative-free optimization both in theory (convergence analysis and complexity control) and in practice (software developments and applications). The talks will be particularly focused on large-scale problems, constrained problems, parallel methods, subspace methods, and randomized methods.
