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...

Fixed point iteration for computing the time elapse operator - Sankaranarayanan, Sipma, et al. - 2006 () Citation Context ... w2 ˙ = w1 + 9w2 + 1 2 w3, w3 ˙ = 2w2 + 16w3 Its initial conditions are given by w1 ∈ [0, 1], w2 ∈ [0, 1], w3 ∈ [0, 1]. We analyze ...
I have the fixed point iteration x(i+1) = g(xi) where g(x) = 1 - 5x + 15/2x^2 - 5/2x^3. From this I have to find initial guesses for which FPI cycles endlessly through interval (0, 1), interval (1, 2) and when it diverges to infinity. ...
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...
It is easy to understand that each fixed point of this iteration is a solution of (6.4), and vice versa. To study this fixed-point iteration, we need some concepts about cones. Let E be a real Banach space. If P is a nonempty closed and convex set in E where • x∈ P and λ...
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- ...
