   <abstract xml:lang="ru">
    <p>В работе описывается методика применения вариационно-комбинаторного подхода при решении обратных линейных и нелинейных задач геофизики в рамках теории дискретного потенциала. Информация, получаемая благодаря дистанционному зондированию Земли и планет, носит исключительно дискретный характер, несмотря на поистине огромные массивы данных. Комбинаторные методы дискретной математики позволяют, если можно так выразиться, организовать «селективный отбор» информации о физических полях: аналитические аппроксимации строятся только по тем значениям элементов поля, которые могут быть надежно идентифицированы как полезный сигнал, а не случайная или систематическая помеха.</p>

    <p>Variational-combinatoric approach is used when solving linear and nonlinear inverse problems of geophysics within the framework of discrete potential. The acquired data about physical fields and their sources are of discrete character. Combinatoric methods of discrete mathematics allow us to organize some selective choice of the information on the physical field elements. Analytical approximations are built only by means of verified data which can be recognized as useful signal, not as an arbitrary or systematic noise.</p>
