Moreover , we show that after finite iterations , the unit step is always accepted 此外,我们还证明:经一定的迭代步后,单位步长总可以取到。
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,还证明了经一定的迭代步后,单位步长总可以取到。因此算法在解的局部还原为用单位步长的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 在较弱的条件下,我们证明所提出的方法具有全局收敛性,此外,本文证明在有限次迭代后,单位步长总是可接受的,因此,算法还原为mbfgs法,从而这种方法具有局部超线性收敛性。
