Lagrangian multiplier kkt
Tīmeklisby no means guaranteed that the Lagrangian has any saddle points at all. This can be seen in the problem discussed in Example 3.4: Here the points x∗= ±1 are KKT points (and global solutions) with Lagrange multipliers λ∗= 1/4. However, the points (x ∗,λ) = (±1,1/4) are not saddle points of the Lagrangian in the sense of Definition 4.1, as
