摘要
利用H ilbert空间几何特征,修正了Broyden求解奇异问题的方法.在几乎不增加计算量的前提下,使修正的Broyden方法的渐进收敛速率,由0.618 0提高到0.381 9.
In this paper, the singular problems are solved by using the character of Hilbert Space and modifying Broyden＇ s method. On the condition of the same calculation, the modified Broyden＇ s method is shown to yield a sequence that improves the asymptotic linear rate from 0. 6180 to 0. 3819.
