Optimality Conditions for Constrained Optimization
Theorem 1 3 [Constrained First-Order Optimality Conditions] Let x 2 ⌦ be a local solution to P at which ⌦ is regular Then there exist u 2 Rm such that (1) 0=r xL(xu) (2) 0=u if i(x) for i =1 sand (3) 0 u i i =1 s where the mapping L : Rn ⇥Rm! R is defined by L(xu):=f 0(x)+ Xm i=1 u if i(x) and is called the Lagrangian for |

Optimality Conditions
Optimality Conditions 1 Constrained Optimization 1 1 First–Order Conditions In this section we consider first–order optimality conditions for the constrained problem P : minimize subject to f0(x) x ∈ Ω where f0 Rn Rn : → R is continuously differentiable and Ω ⊂ is closed and non-empty |
Does x Rn satisfy the first-order condition for optimality?
Indeed, this equivalence is the heart of the proof of Theorem 1.3.1. The equivalence of (b) and (c) is an immediate consequence of 1.3.2. In the sequel, we say that x ∈ Rn satisfies the first-order condition for optimality for the convex composite optimization problem if it satisfies any of the three conditions (a)–(c) of Lemma 1.3.2.
What is a first-order optimality measure in a toolbox solver?
Most constrained toolbox solvers separate their calculation of first-order optimality measure into bounds, linear functions, and nonlinear functions. The measure is the maximum of the following two norms, which correspond to Equation 5 and Equation 6: where the norm of the vectors in Equation 7 and Equation 8 is the infinity norm (maximum).
What is first-order optimality?
The meaning of first-order optimality in this case is more complex than for unconstrained problems. The definition is based on the Karush-Kuhn-Tucker (KKT) conditions. The KKT conditions are analogous to the condition that the gradient must be zero at a minimum, modified to take constraints into account.
