Но решение прямой задачи при заданной модели среды и граничных условиях единственно, отклик среды на источник электромагнитного поля уникален. Рассматривается алгоритм, ведущий к точному решению тестовой задачи при стремлении к нулю невязок входных и модельных данных. Используется несколько стартовых моделей среды и два метода оптимизации: нелинейный метод наименьших квадратов с вычислениями матрицы чувствительности и метод на базе метаэвристических алгоритмов, применяемых, когда целевые функции имеют несколько локальных минимумов. С помощью численных расчетов получено устойчивое решение обратной задачи МТЗ для модели 3D-среды.</p></abstract><trans-abstract xml:lang="en"><p>When solving inverse problems of magnetotelluric sounding (MTS), equivalent solutions appear, noticeably different from each other. But the solution of a direct problem under a given medium model and boundary conditions is the only one, the response of the medium to the source of the electromagnetic field is unique. An algorithm is considered that leads to an accurate solution of the test problem when striving for zero inconsistencies in input and model data. Several starting medium models and two optimization methods are used: a nonlinear least squares method with calculations of the sensitivity matrix and a method based on metaheuristic algorithms used when target functions have several local minima. Using numerical calculations, a stable solution of the inverse MTS problem for the 3D-medium model was obtained.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Магнитотеллурическое зондирование</kwd><kwd>обратная задача</kwd><kwd>устойчивое решение</kwd><kwd>трехмерная модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Magnetotelluric sounding</kwd><kwd>inverse problem</kwd><kwd>stable solution</kwd><kwd>three-dimensional model</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при поддержке проекта ФНИ № FWZZ-2022-0025.
