WebDec 11, 2024 · It's possible for a convex optimization problem to have an optimal solution but no KKT points. Constraint qualifications such as Slater's condition, LICQ, MFCQ, etc. are necessary to ensure that an optimal solution will satisfy the KKT conditions. Here, the only feasible point is x 1 ∗ = 0, x 2 ∗ = 0. Thus that point is an optimal solution. Webfrf(x)gunless fis convex.

WebThe KKT conditions are always su cient for optimality. The KKT conditions are necessary for optimality if strong duality holds. We often use Slater’s condition to prove that strong duality holds (and thus KKT conditions are necessary). Slater’s condition implies that strong duality holds for a convex primal with all a ne constraints .
