WebTHE GOLDSTEIN CONDITIONS Like the Wolfe conditions, the Goldstein conditionsensure that the step length α achieves sufficient decrease but is not too short. The Goldstein conditions can also be stated as a pair of inequalities, in the following way: f(xk)+ (1- c)αk∇ fTk pk ≤ f(xk + αkpk)≤ f(xk)+ cαk∇ fTk pk, (3.11) with 0 < c < 1/2.

WebSimilar results to this theorem holds when the Goldstein conditions or strong Wolfe conditions are used. For all these strategies, the step length selection implies this inequality, which we call the Zoutendijk condition. The Zoutendijk condition implies that cos 2 θ k ‖ ∇ f ‖ 2 → 0 Warning How to show this? WebThe Wolfe (or strong Wolfe) conditions are among the most widely applicable and useful termination conditions. We now describe in some detail a one-dimensional search procedure that is guaranteed to ﬁnd a step length satisfying the strong Wolfe conditions (3.7) for any parameters c1and c2 satisfying 0 < c1< c2 < 1. sandy meadows lodge park site map
