“…Variational inequalities have extensively been investigated, see [1,2,15,17,18,20,22,24,[26][27][28] for more details. In 1976, Korpelevich [14] proposed an iterative algorithm for solving VIP (1.1) in Euclidean space R n : y n = P C (x n − τAx n ), x n+1 = P C (x n − τAy n ), ∀n 0, with τ > 0 a given number, which is known as the extragradient method.…”
