本章的目的是调查这一领域最重要的贡献。为此,我们将通过形式为xn+ 1= f(T,xn),n= 0,1,2,.的一般关系来定义不动点迭代过程,(1)其中T:X→ X是一个算子,并且x 0 ∈ X,通过默认考虑f(T,xn)在(1)的右边确实包含定义给定不动点迭代过程的所有参数。例如,在Mann迭代过程M(x 0,αn,T)的情况下,出现在(1)中的f(T,xn),由公式f(T,xn)=(1-αn)xn+αnTxn给出,隐含地包括{αn}。
It is the aim of this chapter to survey the most significant contributions to this area. To this end, we shall define a fixed point iteration procedure by a general relation of the form xn+ 1= f (T, xn), n= 0, 1, 2,...,(1) where T: X→ X is an operator and x0∈ X, by tacitly considering that f (T, xn) in the right-hand side of (1) does contain all parameters that define the given fixed point iteration procedure. For example, in the case of Mann iteration procedure M (x0, αn, T), f (T, xn) appearing in (1), given by the formula f (T, xn)=(1− αn) xn+αnTxn implicitly includes {αn}.
