Abstract
A method for solving linear systems of equations with sign-definite self-adjoint operator matrix by the Richardson iteration method in case of the absence of information about the lower spectral bound of a problem is presented. The algorithm is based on the simultaneous operation of two competing iterative processes, the effectiveness of which is constantly analyzed. The method is explained on an example of one-dimensional steady-state heat equation.
