В настоящей работе рассматривается задача, в которой требуется определить, существует ли в заданном 3n-вершинном расщепляемом графе n попарно непересекающихся порожденных подграфов, изоморфных простой цепи порядка 3. Разработан полиномиальный алгоритм, который решает эту задачу. В его основе лежит техника увеличивающих подграфов. Алгоритм может найти применение при решении задач формирования команд.</p></abstract><trans-abstract xml:lang="en"><p>The study of the computational complexity of problems on graphs is an urgent problem. We show that the problem of deciding whether the vertex set of a given split graph of order 3n can be partitioned into induced subgraphs isomorphic to P3 is a polynomially solvable problem. We develop a polynomial-time algorithm based on the method of augmenting graphs. The developed efficient algorithm can be used for solving team formation problems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>разбиение графа на специальные подграфы</kwd><kwd>расщепляемый граф</kwd><kwd>полиномиальный алгоритм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>partitioning a graph into certain subgraphs</kwd><kwd>split graph</kwd><kwd>polynomial-time algorithm</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Лекции по теории графов / В.
