Moreover , we show that after finite iterations , the unit step is always accepted 此外,我們還證明:經(jīng)一定的迭代步后,單位步長總可以取到。
Moreover , we prove that after finite iterations , the unit step is always accepted and the proposed method essentially reduces to the modified bgs method with the unit steplength 此外,還證明了經(jīng)一定的迭代步后,單位步長總可以取到。因此算法在解的局部還原為用單位步長的bfgs算法。
Under mild conditions , we prove that the proposed method is globally convergent . moreover , we show that after finite iterations , the unit step is always accepted , and the method locally reduces to the modified bfgs method 在較弱的條件下,我們證明所提出的方法具有全局收斂性,此外,本文證明在有限次迭代后,單位步長總是可接受的,因此,算法還原為mbfgs法,從而這種方法具有局部超線性收斂性。
