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- ...
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...
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. ...
it provides a method (generally, iterative) for constructing the fixed point(s); (b) it is able to provide information on the error estimate or / and rate of convergence of the iterative process used to approximate the fixed point; and (c) it can give concrete information on the stability...
