## On enhanced KKT optimality conditions for smooth nonlinear optimization

The Fritz-John (FJ) and KKT conditions are a fundamental tool to characterize minimizers and lie in the root of almost any method for constrained optimization. Since the seminal works of Fritz John, Karush, Kuhn and Tucker, FJ/KKT conditions have been enhanced by adding extra necessary conditions. Such an extension was first proposed by Hestenes in … Read more
