Abstract: In this work the well known variational iteration method is used for finding the solution of a semi-linear inverse parabolic equation. This method is based on the use of Lagrange multipliers for identification of optimal values of parameters in a functional. Using this method a rapid convergent sequence is produced which tends to the exact solution of the problem. Thus the variational iteration method is suitable for finding the approximation of the solution without discretization of the problem. We will change the main problem to a direct problem which is easy to handle the variational iteration method. To show the efficiency of the present method, several examples are presented. Also it is shown that this method coincides with Adomian decomposition method for the studied problem.
