摘要

The purpose of this work is to refine the inertial subgradient extragradient algorithm for solving variational inequality problems in real Hilbert spaces. Under the new assumptions, the cost operator does not need any monotonicity. Moreover, the advantage of the proposed algorithm is that the analysis and proof of its weak convergence use self-adaptive step-sizes without requiring the Lipschitz continuity condition and any line-search rules or adding projection onto the feasible subset. The results of this paper provide new insights into non-monotone variational inequality problems and non-Lipschitz continuity, extending and enriching existing results in the literature. Finally, we give numerical experiments to illustrate the effectiveness of our proposed algorithm.
