摘要

本文研究了实希尔伯特空间中的常见变分包容问题。为了解决这个问题,我们提出了一种具有两个初始参数步长的新加速方法,并建立了一个强收敛定理。我们的方案结合了粘度近似法和曾氏前向后向分裂法,并使用自适应步长。我们在每次迭代的第一步同时计算惯性外推法和粘度近似法。我们证明,在常规和适当的假设条件下,迭代法收敛性很强。我们还研究了普通最小点问题、分割可行性问题以及最小绝对选择和收缩算子(LASSO)的一些应用。最后,我们介绍了希尔伯特空间中的两个数值结果以及对 LASSO 问题的一个应用,以说明所考虑方法的收敛性分析,并将我们的结果与 Cholamjiak 等人 (J. Sci. Comput., 88(85), 2021) 以及 Gibali 和 Thong (Calcolo, 55(49), 2018) 所介绍的相关结果进行比较。

A new algorithm for approximating solutions of the common variational inclusion

A new algorithm for approximating solutions of the common variational inclusion

This paper studies the common variational inclusion problem in real Hilbert spaces. To solve this problem, we propose a new accelerated approach with two initial parameter steps and establish a strong convergence theorem. Our scheme combines the viscosity approximation method with Tseng’s forward backward-forward splitting method and uses self-adaptive step sizes. We simultaneously compute the inertial extrapolation and viscosity approximation at the first step of each iteration. We show that the iterative method converges strongly under conventional and appropriate assumptions. We also study some applications to the common minimum point problems, split feasibility problems, and to the least absolute selection and shrinkage operators (LASSO). Finally, we present two numerical results in Hilbert space and an application to the LASSO problem in order to illustrate the convergence analysis of the considered methods as well as compare our results to the related ones introduced by Cholamjiak et al. (J. Sci. Comput., 88(85), 2021) and Gibali and Thong (Calcolo, 55(49), 2018).

期刊介绍: Computational & Applied Mathematics began to be published in 1981. This journal was conceived as the main scientific publication of SBMAC (Brazilian Society of Computational and Applied Mathematics). The objective of the journal is the publication of original research in Applied and Computational Mathematics, with interfaces in Physics, Engineering, Chemistry, Biology, Operations Research, Statistics, Social Sciences and Economy. The journal has the usual quality standards of scientific international journals and we aim high level of contributions in terms of originality, depth and relevance.
