不动点迭代 Fixed-Point Iteration 首先,什么是不动点 定义(不动点 fixed point) 若g(p)=p 则称p 是函数 g 的不动点,即 p 是方程 g(x)-x=0 的一个根 比如对于 g(x)=x 所有点都是不动点;若 g(x) = x^2-2 那么不动点 p 满足p^2-2=p ,所以 p=-1 且p=2 什么样的函数存在一个...
求解f(x)=0还是很有用的,具体应用此不做讨论。这里将使用一系列专题阐述求解f(x)=0的各种方法。此次先讨论固定点迭代法(Fixed Point Iteration)。 下面先直接给出解法,后面再对原理进行阐述。 【问题描述】 已知f(x)=0,求使等式成立的x的值。

FIXED POINT ITERATION FOR LOCAL STRICTLY PSEUDO-CONTRACTIVE MAPPING XINLONG WENG (Communicated by Paul S. Muhly) Abstract. A fixed point of the local strictly pseudo-contractive mapping is obtained as the limit of an iteratively constructed sequence with an error esti- ...
Loadrunner中,我们在参数列表里面设置参数时,需选择值的调用方式(update value on)each iteration,each occurrence和once。 如何来区别这三种方式呢? each iteration是指每迭代一次取一次值; each occurrence是指每发生一次取一次值; once是指仅取一次值。 假如参数为{department},其参数值有四种【如果只...解决...
看论文的时候出现了投影不动点迭代的概念,在网上搜索了一圈也没有看到太多相关的东西。 只看到了很多凸优化方面的不动点迭代内容,先粘个参考链接,学懂了前来补充~ 投影的概念和不动点迭代的结合 不动点迭代 不动点迭代的概念在第1个参考链接里描述的比较明确,梯度等于0 x与算子之间的关系,画图来看就是函数曲线...
fixed point iterationThis paper provides a survey of iteration procedures that have been used to obtain fixed points for maps satisfying a variety of contractive conditions. The author does not claim to provide complete coverage of the literature, and admits to certain biases in the theorems that ...
