摘要:

On the setof then-dimensional 0 – 1 vectors with at least ϱ positive components a semi-ordering is introduced. Each real valued functionf(x), defined on, withf(x) ≦f(y) forx<yis called 0 – 1 – ρ-monoton increasing. Combinatorial algorithms, presented by the authors for linear 0 – 1-programming, are extend to 0 – 1-programming problems with 0 – 1 – ρ-monoton increasing objective function and arbitrary restrictions.

摘要:

This paper presents a new extremal approach to deriving dual optimization problems with proper duality inequality which simplifies, and generalizes the Fenchel-Rockafellar scheme. Our derivation proceeds in two stages, (i) inequality attainment,(ii) decoupling primal and dual variables, The power and convenience of this approach are exhibited through a new, much simpler derivation of the Charnes-Cooper results for Khinchin-Kullback-Leibler statistical estimation [1], the immediate establishment of the C2duality for general distributions and its extensions to general linear inequality constraints, plus the development of a new two-person zero-sum game connection.

摘要:

Cutting plane and column generation algorithms are known to be dual in a certain sense. In this paper, a general cutting plane algorithm of Kelley type for convex programs and a general column generation algorithm of Dantzig-Wolfe type for Wolfe's generalized program are described. These two algorithms are shown to be dual. An estimation of the optimal value known for Dantzig-Wolfe methods is carried over to cutting plane methods.

摘要:

An upper bound of the number of switch-over points of extremal controls is given for certain linear controllable systems with stationary equations of motion and a set of feasible controls in form of any compact convex polyhedron, For these investigations results of the linear parametric programming are used.

摘要:

LetKbe a closed convex order-bounded set of an order-complete vector lattice and letAbe a him continuous linear operator. Then the equalityAK=A(extK) is proved, where extKis the set of all extremal points ofK. It is shown that various generalizations of the Ljapunov-theorem on the range of vector-measures are special cases of this general statement.
