KW - Nonlinear saddle point problem, inexact Uzawa algorithm,  preconditioned,  convergence analysis, numerical experiments.
AB - <p style="text-align: justify;">In this paper, we consider the inexact Uzawa algorithm for solving the nonlinear saddle point problem. Based on the energy norm, some sufficient conditions are given for the convergence of the algorithm, and the error analysis is also presented. Moreover, some numerical results are reported to illustrate the efficiency of the considered algorithm.</p>
