Abstract
In this paper, the variational iteration method is applied to solving an inverse problem of determining more than one unknown parameters in a linear parabolic equation with Neumann boundary conditions. If one of boundary conditions is considered as unknown, it is desirable to be able to determine more than one parameter from the given data. This method is based on the use of Lagrange multipliers for identification of optimal valuse of parameters in a functional. We get a rapid convergent sequence tending to the exact solution of the inverse problem. To show the efficiency of the present method, one interesting example is presented.
