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 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- ...

These methods leverage fixed-point and weight-splitting schemes for computation. The study demonstrates the convergence of the proposed schemes to nonnegative solutions of the SARE in specific situations. Additionally, various numerical examples illustrate the effectiveness of these schemes in solving ...
