An approximate proximal-extragradient type method for monotone variational inequalities. (English) Zbl 1068.65087
One of the most known approaches to constructing solution methods for monotone variational inequalities consists in incorporating a predictor step for computing parameters of a separating hyperplane and for providing the Fejér-monotone convergence. This approach is also known as combined relaxation; see {\it I. V. Konnov} [Russ. Mathem. (Iz. VUZ), 37, No. 2, 44--51 (1993; Zbl 0835.90123)] and can be extended in several directions. {\it M. V. Solodov} and {\it B. F. Svaiter} [Math. Progr. 88, 371--389 (2000; Zbl 0963.90064)] proposed an inexact proximal point iteration as the predictor step. The authors suggest a modification of this method which involves an additional projection iteration for completing the predictor step. The method possesses the same convergence properties. Some results of numerical experiments on a network equilibrium problem are reported.
