An adaptive stochastic gradient-free approach for high-dimensional blackbox optimization
Anton Dereventsov, Clayton G. Webster, Joseph D. Daws
In this work, we propose a novel adaptive stochastic gradient-free (ASGF) approach for solving high-dimensional nonconvex optimization problems based on function evaluations. We em…
