"WebKKT Conditions For an unconstrained convex optimization problem, we know we are at the global minimum if the gradient is zero. The KKT conditions are the equivalent condi-tions for the global minimum of a constrained convex optimization problem. If strong duality holds and (x ∗,α∗,β∗) is optimal, then x minimizes L(x,α∗,β∗) " - Convex kkt
