    Variable Metric Methods for Nonsmooth Optimization

  • Original language description

    A variable metric method is introduced for nonsmooth unconstrained optimization, which has a feature of both standard variable metric methods and standard bundle methods. This method is competitive with standard bundle methods measured by number of iterations, but it is more efficient than these methods measured by computational time, since it does not use any time consuming quadratic programming subalgorithm. Numerical comparisons of this method with standard methods are given.

    Metody s proměnnou metrikou pro nehladkou optimalizaci

  • Czech description

    V příspěvku je uvedena metoda s proměnnou metrikou pro nehladkou nepodmíněnou optimalizaci, která má vlastnosti standardních metod s proměnnou i standardních svazkových metod. Tato metoda konkuruje standardním svazkovým metodám co do počtu iterací , aleje mnohem rychlejší, neboť nepoužívá časově náročné řešení úloh kvadratického programování. Je uvedeno numerické porovnání této metody s oběma standardními metodami.
