摘要

本文提出了一种改进的自适应惯性次梯度外聚算法,该算法将两个投影投影到半空间上。此外,在温和的条件下,我们得到了在实数Hilbert空间中近似变分不等式问题的公共解和有限半收缩映射族的公共不动点的算法所生成的序列的强收敛性。该算法的主要优点是:在不知道相关单调算子的Lipschitz常数的前提下得到强收敛结果;在半空间上进行两个投影;采用惯性技术加快了收敛速度。最后,我们给出了一个应用和一个数值例子来说明我们的算法的有效性和适用性。

A new inertial-projection algorithm for approximating common solution of variational inequality and fixed point problems of multivalued mappings
In this paper, we present a new modified self-adaptive inertial subgradient extragradient algorithm in which the two projections are made onto some half spaces. Moreover, under mild conditions, we obtain a strong convergence of the sequence generated by our proposed algorithm for approximating a common solution of variational inequality problem and common fixed point of a finite family of demicontractive mappings in a real Hilbert space. The main advantages of our algorithm are: strong convergence result obtained without prior knowledge of the Lipschitz constant of the related monotone operator, the two projections made onto some half-spaces and the inertial technique which speeds up rate of convergence. Finally, we present an application and a numerical example to illustrate the usefulness and applicability of our algorithm.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
