On team decision problems with nonclassical information structures

AA Malikopoulos - IEEE Transactions on Automatic Control, 2022 - ieeexplore.ieee.org
In this article, we consider sequential dynamic team decision problems with nonclassical
information structures. First, we address the problem from the point of view of a “manager” …

Separation of learning and control for cyber–physical systems

AA Malikopoulos - Automatica, 2023 - Elsevier
Most cyber–physical systems (CPS) encounter a large volume of data which is added to the
system gradually in real time and not altogether in advance. In this paper, we provide a …

[KNYGA][B] Finite Approximations in discrete-time stochastic control

N Saldi, T Linder, S Yüksel - 2018 - Springer
Control and optimization of dynamical systems in the presence of stochastic uncertainty is a
mature field with a large range of applications. A comprehensive treatment of such problems …

A universal dynamic program and refined existence results for decentralized stochastic control

S Yüksel - SIAM Journal on Control and Optimization, 2020 - SIAM
For sequential stochastic control problems with standard Borel measurement and control
action spaces, we introduce a general (universally applicable) dynamic programming …

Convex analysis in decentralized stochastic control, strategic measures, and optimal solutions

S Yuksel, N Saldi - SIAM Journal on Control and Optimization, 2017 - SIAM
This paper is concerned with the properties of the sets of strategic measures induced by
admissible team policies in decentralized stochastic control and the convexity properties in …

Optimality of independently randomized symmetric policies for exchangeable stochastic teams with infinitely many decision makers

S Sanjari, N Saldi, S Yüksel - Mathematics of Operations …, 2023 - pubsonline.informs.org

identical interest stochastic dynamic games) with large or countably infinite numbers of …

Zero-sum games involving teams against teams: Existence of equilibria, and comparison and regularity in information

I Hogeboom-Burr, S Yüksel - Systems & Control Letters, 2023 - Elsevier
Many emerging problems involve teams of agents taking part in a game. Such problems
require a stochastic analysis with regard to the correlation structures among the agents …

Controlled diffusions under full, partial and decentralized information: Existence of optimal policies and discrete-time approximations

S Pradhan, S Yüksel - arxiv preprint arxiv:2311.03254, 2023 - arxiv.org
We present existence and discrete-time approximation results on optimal control policies for
continuous-time stochastic control problems under a variety of information structures. These …
