Webare called the Karush-Kuhn-Tucker (KKT) conditions. Remark 4. The regularity condition mentioned in Theorem 1 is sometimes called a constraint quali- cation. A common one is that the gradients of the binding constraints are all linearly independent at x . There are many variations of constraint quali cations. We will not deal with these in ...
