WebNov 11, 2024 · You need to be able to express the solution to the inner level optimization problem as the solution to the Karush Kuhn Tucker (KKT) first order optimality conditions. This can be done for any convex optimization problem satisfying a KKT constraint qualification, in which case 1st order KKT conditions are necessary and … WebMay 22, 2024 · Most students learn the first-order optimality conditions for unconstrained optimization in a first course, but sometimes that course gets everyone too stuck on the idea of computing a gradient. What is really happening is that the function should be “flat in all directions,” i.e. all directional derivatives are zero.
