Предлагаемый способ использует наследование решений порождающих задач, при котором оценка вариантов порожденных задач о назначении проводится методом коррекции дерева кратчайших путей приращений. Реоптимизация дерева путей приращений на структурах смежности приводит к гарантированному снижению вычислительной сложности задачи на порядок.</p></abstract><trans-abstract xml:lang="en"><p>The problem of the solution of asymmetric traveling salesman problem with sparse matrix, based on branch and bound techniques with linear assignment problems relaxation, is considered. Inheritance of the result’s data of previous problems and its reoptimization allows to decreasing time of reception of the new solution on branch’s tree path. The reoptimization algorithm, based on a Shortest Augmenting Path method, is offered.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>задача коммивояжера</kwd><kwd>метод ветвей и границ</kwd><kwd>вычислительная сложность</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">Miller D., Pekny J. // Science. 1991.
