Cybernetics and Systems Analysis Aims and scope

Abstract

Using exact penalty functions in schemes of decomposition in variables for nonlinear optimization make it possible to overcome problems related to implicit description of the feasible region of master problem. The paper deals with determining the values of penalty coefficients in such an approach. In the case where the functions of the original problem are not defined on the whole space of variables, the author proposes to use convex extension of functions.
