摘要

In this paper, we address a general bilevel variational inequality problem that incorporates variational inequalities defined over the intersection of the common fixed points of a finite family of generalized demimetric mappings and the solutions to a quasi-monotone variational inequality. We introduce a novel projection contraction-type algorithm that employs an inertial approach with three correction terms to accelerate convergence. We establish the strong convergence of the proposed algorithm under appropriate conditions on the parameters. Additionally, we provide numerical examples to illustrate and assess the effectiveness of our method.
