Implicit Iterative Method for Hierarchical Variational Inequalities
We introduce a new implicit iterative scheme with
perturbation for finding the approximate solutions of a hierarchical variational inequality, that is, a variational inequality over the
common fixed point set of a finite family of nonexpansive mappings. We establish some convergence theorems for the sequence
generated by the proposed implicit iterative scheme. In particular, necessary and sufficient conditions for the strong convergence
of the sequence are obtained
Synchronal Algorithm and Cyclic Algorithm for Hierarchical Fixed Point Problems and Variational Inequalities
We propose synchronal algorithm and cyclic algorithm based on the general iterative method for solving a hierarchical fixed point problem. Under suitable parameters, the iterative sequence converges strongly to a common fixed point of nonexpansive mappings and also the unique solution of a variational inequality. The results
presented in this paper improve and extend the corresponding results reported recently by some authors. Furthermore, a numerical example is given to demonstrate the effectiveness of our iterative schemes
Strong Convergence of an Iterative Algorithm for Hierarchical Problems
We introduce the triple hierarchical problem over the solution set of the variational inequality problem and the fixed point set of a nonexpansive mapping. The strong convergence of the algorithm is proved under some mild conditions. Our results extend those of Yao et al., Iiduka, Ceng et al., and other authors
