V. I. Tsurkov Sov. Math. Dokl. , 22 , 01.1980 , p. 726-728, language: английский ISSN 0197-6788  Аннотация A method is proposed for decomposition on the basis of macrovariable introduction, which is applicable to a wide class of extremal problems described by partial differential equations of various types. The main point of the method is blockwise aggregation scheme, used for a particular linear programming problem.  Ключевые слова elliptic partial differential equations; global constraints; global constraints; iterative method; monotony
