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.
WebAgain, KKT gives us a complementary slackness condition: m.R = 0 and the sign condition for the inequality constraints: m ≥ 0.
