A new method of the extragradient type for the approximate solution of variational inequalities with pseu-domonotone and Lipschitz-continuous operators acting in a finite-dimensional linear normed space is proposed. This method is a modification of the subgradient extragradient algorithm using the Bregman divergence instead of the Euclidean distance. A theorem on the convergence of the method is proved, and, in the case of a monotone operator, non-asymptotic estimates of the effectiveness of the method are obtained.
