Численное решение обратной задачи Коши для эллиптического уравнения

This paper is interested at the Cauchy problem for Laplace's equation, which is to recover Dirichlet condition on the accessible part of the domain from additional conditions on the other part of domain. To solve this kind of ill-posed problem, we use a variational iterative method. Also, a direct method for numerical solution of the inverse boundary value problem is presented.
