Abstract
The paper presents a new iterative algorithm based on Mann-type subgradient extragradient method to solve pseudomonotone variational inequalities and fixed point problems of quasi-nonexpansive mappings in real Hilbert spaces. Our algorithm, employing inertial technique in each iteration, significantly enhances its convergence. We prove a strong convergence theorem under suitable conditions imposed on the operators and parameters, without prior knowledge of the Lipschitz constant. The efficacy and validity of the proposed method are confirmed through several numerical experiments.
