چکیده

This study presents the process of using extrapolation methods to solve the nonlinear Volterra-Fredholm integral equations of the second kind. To do this, by approximating the integral terms contained in equations by a quadrature rule, the nonlinear Volterra-Fredholm integral equations of the second kind are reduced to a set of nonlinear algebraic equations, then the solution of the corresponding system of nonlinear equations is approximated by an iterative method, and finally, these iterations are accelerated by an extrapolation method. We demonstrate the effectiveness of the proposed approach by solving some numerical examples.
