WebMay 3, 2016 · The KKT conditions have been generalized in various directions: to necessary or sufficient conditions, or both types, for an extremum of a function subject to equality or inequality constraints [6]; especially in case of convex functions $f$ and $g_i$ and affine $h_j$, the KKT conditions \eqref {eq:1} are sufficient, see [9], pp. 243–246. WebAs shown in the previous subsection, the KKT conditions represent necessary conditions to obtain a local optimum. Since LP problems are convex, the conditions become also sufficient to define a global optimum: hence, a problem solution exists, and it is optimal iff there are multipliers that satisfy the KKT conditions.
