In this paper, two flow charts for solving the same inverse problem by an optimization method are presented. On numerical examples it is shown that the first flow chat often used by researchers requires much more computer costs than the second one. This is because of the necessity of using a fine net and due to an increase in the number of minimization iterations of the residual functional for its decrease up to a certain value.
