First-order necessary condition for optimality Suppose that f is a C1 (continuously di erentiable) function and x is its local minimum Pick an arbitrary vector d 2 Rn Since we are in the unconstrained case moving away from x in the direction of dor d cannot immediately take us outside D In other words we have x + d2 Dfor all 2 R close |
What is the first-order necessary condition for constrained optimality?
The first-order necessary condition for constrained optimality generalizes the corresponding result we derived earlier for the unconstrained case. The condition ( 1.25) together with the constraints ( 1.18) is a system of equations in unknowns: components of plus components of the Lagrange multiplier vector .
How do you find the second order necessary condition?
Theorem 2 (Second-Order Necessary Condition) Let f (x) be a C2 function where x Rn. Then, if x Furthermore, if 2f (x) 0, then the condition becomes sufficient. 8 0 . Hessian would be a descent direction from x. Again, they may still not be sufficient, e.g., f (x) = x3.
What is the RST-order necessary condition for optimality?
Since d was arbitrary, we conclude that This is the rst-order necessary condition for optimality. A point x satisfying this condition is called a stationary point. The condition is \\ rst-order" because it is derived using the rst-order expan-sion (1.5). We emphasize that the result is valid when f 2 C1 and x is an interior point of D.
Is f ′′(x) second-order necessary condition (SONC) sufficient?
It is necessary f ′′(x) second-order necessary condition (SONC), which we would explored further. These conditions are still not, in general, sufficient. It does not distinguish between local minimizers, local maximizers, or saddle points. convex, then x is a local minimizer.
