Предложен полиномиальный алгоритм построения наибольших клиринговых матриц в финансовых сетях с правилом ограниченных равных выплат, используемым при распределении имеющегося у агента денежного резерва между его кредиторами. Предполагается, что исходный денежный резерв каждого из агентов равен нулю (между кредиторами распределяются лишь средства, получаемые от других агентов). Алгоритм основан на использовании выявленных свойств взвешенных сильно связных графов. Получены необходимые и достаточные условия, при которых наибольшая клиринговая матрица отлична от нулевой при нулевых денежных резервах агентов.</p></sec><sec><title>Заключение</title><p>Заключение.

A polynomial-time algorithm for constructing the greatest clearing matrices for financial networks with a rule of constrained equal awards for the distribution of the agent's estate between its creditors is proposed. It is assumed that the cash reserves of each agent are equal to zero (funds received from other agents are distributed among creditors). The algorithm is based on the use of the identified properties of weighted strongly connected graphs. Necessary and sufficient conditions are obtained under which the greatest clearing matrix is different from zero at zero cash reserves of agents'.</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed approach can be used in constructing clearing algorithms for financial networks with other rules for distributing the agent’s estate between its creditors.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>финансовая сеть</kwd><kwd>клиринговая матрица</kwd><kwd>правила распределения средств агента</kwd><kwd>представление сети графом</kwd><kwd>сильно связный граф</kwd></kwd-group><kwd-group xml:lang="en"><kwd>financial network</kwd><kwd>clearing matrix</kwd><kwd>rules for distribution of the agent's estate</kwd><kwd>graph representation of the network</kwd><kwd>strongly connected graph</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Автор благодарит кандидата физико-математических наук В.
