This makes the proposed computational scheme potentially highly efficient for solving a wide class of high-dimensional problems on modern high-performance computing platforms, such as <bold>Nvidia Cuda</bold>. It is shown that the proposed algorithms can be used to solve ill-conditioned linear systems and least squares problems, as well as to construct iterative regularization algorithms. The results of computational experiments are presented, confirming the effectiveness of the proposed computational algorithms.</p></abstract><trans-abstract xml:lang="ru"><p>Предложена новая версия неявной итерационной схемы, для реализации которой требуются лишь матрично-векторные вычислительные процедуры. Это делает предлагаемую вычислительную схему потенциально высокоэффективной для решения широкого класса задач большой размерности на современных высокопроизводительных вычислительных платформах, например <bold>Nvidia Cuda</bold>. Показано, что предлагаемые алгоритмы могут быть использованы для решения плохо обусловленных линейных систем и задач наименьших квадратов, а также для построения итерационных алгоритмов регуляризации. Приводятся результаты вычислительных экспериментов, подтверждающие эффективность предлагаемых вычислительных алгоритмов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>implicit iterative scheme</kwd><kwd>simple iteration method</kwd><kwd>ill-conditioned problems</kwd><kwd>Ben–Israel iterative pseudo-inversion</kwd><kwd>iterative regularization</kwd><kwd>matrix-vector operations</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>неявная итерационная схема</kwd><kwd>метод простых итераций</kwd><kwd>плохо обусловленные задачи</kwd><kwd>итерационное псевдообращение Бен–Израэля</kwd><kwd>итерационная регуляризация</kwd><kwd>матрично-векторные операции</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Sun L., Wei Y., Zhou J.
