摘要
本文提出了二类新的摄动可行方向法,发展和完善了这类方法.新方法形式简单而且不必用Polak程序.适当选择算法中有关参数可减少计算量,还可加快算法的收敛速度.
This paper presents two classes of new perturbed feasible direction methods which develop and complete this kind of methods^([1.2]). The new methods are simple in form and the Polak' s procedure need not be used in them. When selecting the parameters in the methods properly, the computations can be reduced and the rate of convergence may be accelarated.
