It is shown that all the iteration methods with third-order convergence are equivalent to the standard Tchebyshev method. The acceleration of the convergence of the Newton method is also considered. New iteration methods on the procedure discussed above are proposed. Comparison between different iteration methods is given by test examples.</abstract><trans-abstract xml:lang="ru">В данной работе изучены итерационные методы высокого порядка сходимости для решения нелинейных уравнений. Показано, что все методы третьего порядка сходимости эквивалентны эталонному методу Чебышева. Рассмотрены приёмы ускорения сходимости метода Ньютона. На этой основе предложены новые итерационные методы. На тестовых примерах сделано сравнение различных итерационных методов.</trans-abstract><kwd-group xml:lang="en"><kwd>Newton method</kwd><kwd>iteration methods</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>метод Ньютона</kwd><kwd>итерационные методы</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Aslam N.
