WebMar 6, 2024 · It is know that if the problem is convex then we can use the KKT conditions to find the solution. However, is it still possible to use the KKT conditions in the same way if the objective function is quasi-convex instead of being convex. (I mean with turning the original problem into feasibility problems.) Thanks in advance. optimization Web2.1 Stochastic Nonconvex Optimization To show that private optimization has the same order of util-ity with nonprivate optimization, we invoke the same set of assumptions for both by following [Yuan et al., 2024; Zhao et al., 2024; Ramezani-Kebrya et al., 2024].
