Optimal Control Problem for Switched System with the Nonsmooth Cost Functional

open access: yesAbstract and Applied Analysis, 2013
We examine the relationships between lower exhausters, quasidifferentiability (in the Demyanov and Rubinov sense), and optimal control for switching systems.

Optimality conditions for distributive justice [PDF]

open access: yesInternational Transactions in Operational Research, 2010
AbstractThis paper uses optimization theory to address a fundamental question of ethics: how to divide resources justly among individuals, groups, or organizations. It formulates utilitarian and Rawlsian criteria for distributive justice as optimization problems.

On the problem of optimal control in the coefficients of an elliptic equation

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
In this paper we consider the optimal control problem for linear elliptic equations of the second order. Control functions are included in the coefficients of the equation for the state, including the coefficients of the highest derivatives.
