It is well known that the variational inequalities are equivalent to the fixed point problems. A new three-steps iterative algorithm is proposed for general variational inequalities based on the equivalence. The new algorithm includes the known two-steps iterative algorithm as special case, and modifies the iterative algorithm with the third-step iteration scheme by using the technique of updating. The convergence of the algorithm is proved under mild conditions. The results in this paper can be viewed as an improvement and extension of the previously known results for general variational inequalities.
