摘要:

The equivalence of the notions of independence systems and monotone boolean functions is proved. This result permits to establish some new connections between discrete analysis and discrete optimization. We discuss possible directions of research following from these connections. Some Questions connected with the reducibility of general in-dependence systems to threshold ones are also considered.

摘要:

A necessary and sufficient condition for a distance matrix which can be reduced to a matrix with fulfilled triangle inequality is presented. If the reduced matrix fulfills the triangle inequality then the dimension of the original traveling salesman problem can be at least halved.

摘要:

A method is developed to solve a special integer programming problem with additional performance functionals. Using this method three different types of problems are to be solved successively. For each of these problems the solutions are given explicitely.

摘要:

At first discrete-differential processes are reduced to “shortest-path-problems” in graphs without approximation. For vector minimum problems, especially shortest-path-problems with vector-valued lengths of arcs, the notion of an optimal-efficient solution,. of an optimal-efficient path resp. with regard to a real-valued valuation is introduced. To compute an optimal-efficient path, analog of the algorithms of Bellman, Ford, Floyd and Dantzing for vector-valued lengths of arcs and generalized measures of paths are given.

摘要:

The aim of this paper consists in constructing and investigating such extremal problems that methods of feasible directions and penalty methods generate sequences having at least two accumulation points.

摘要:

In this paper we derive a modified Hooke-Jeeves and a modified Choit-Schack method for nonlinear, unconstrained programming problems. We illustrate on some numerical examples the applicability and the accuracy of these modifications.
