Significant changes are introduced in Czech and Russian Enterprise management as part of the economic reforms, particularly in enterprise goals and decentralization of managerial authority. This paper reviews major aspects of this new managerialism and hints that there may be a "theory of convergence" in the making in communist countries. [ABSTRACT FROM AUTHOR]

The purpose of this paper is to furnish a computational scheme for a class of programming problems with nonlinear constraints. The algorithm is sequential in nature, producing a sequence of feasible solutions whose limit points are optimal solutions of the original problem. Further, with a view to accelerating convergence we suggest two variants of the solution procedure. [ABSTRACT FROM AUTHOR]

In the generation of an additional constraint or cut for integer programming introduced by Ralph Gomory, there is a certain parameter whose value is customarily chosen so that one of the original variables has a zero coefficient in the cut-equation. In this paper we consider alternative values of the parameter and refer to any linear combination of the original source equation and this cut as a "generalised cut." Attention is then focused, as customary, on those cuts of this type for which the original variable has a zero coefficient. In particular, we show how to determine values for Gomory's parameter so that only a subset of the feasible solutions to the cuts used by Gomory's method of integer forms are feasible for the generalized cuts.

A callback policy must balance the reduced yield (and higher cost) from additional callbacks against the benefits of a more representative final sample. This study provides evidence on the rate at which sample values converge on their estimated population distribution as the number of callbacks increases. [ABSTRACT FROM AUTHOR]
