摘要

摘要利用动态步长技术,在存在惯性项的情况下,提出了一种新的自适应cq算法,用于求解包含有限个极大单调集值算子的凸可行性问题和单调包含问题。为此,在一定的Banach空间中构造了一个收敛于右Bregman强非扩张映射不动点的算法,并同时解决了凸可行性和单调包含问题。该算法在不计算相关算子范数的情况下具有较强的收敛性。文中还给出了有趣的数值例子,说明了该方案的实现和有效性。通过这项工作获得的结果在文献中改进和扩展了以前的同类结果。

A new self-adaptive inertial CQ-algorithm for solving convex feasibility and monotone inclusion problems
Abstract Using a dynamical step size technique, a new self-adaptive CQ-algorithm is proposed in the presence of an inertial term to find the solution of convex feasibility problem and monotone inclusion problem involving a finite number of maximal monotone set valued operators. To do this, in certain Banach spaces, we construct an algorithm which converges to the fixed point of right Bregman strongly nonexpansive mappings and coincidentally solves the convex feasibility and monotone inclusion problems. Strong convergence of the algorithm is achieved without computation of the associated operator norms. Interesting numerical examples which illustrate the implementation and efficiency of our scheme are also given. Results obtained via this work improve and extend on previous results of its kind, in the literature.
