Information-Theoretic Meta Dynamic Programming for Signalling and Control of POMDPs
Charalambos D. Charalambous, Stelios Louka, Photios A. Stavrou
In this paper, we study the information-theoretic characterization of simultaneous signalling and control over channels modeled by partially observable Markov decision processes (P…

Private and Common Information States in Decentralized Parallel Dynamic Programming for Delayed Sharing Patterns
Charalambos D. Charalambous, Umarbek Guvercin, Seddik Djouadi
This paper develops a dynamic programming (DP) approach for decentralized stochastic optimal control problems with delayed sharing information patterns, which exhibits the fundamen…

General Decentralized Stochastic Optimal Control via Change of Measure: Applications to the Witsenhausen Counterexample
Bhagyashri Telsang, Seddik Djouadi, Charalambos D. Charalambous
In this paper we present global and person-by-person (PbP) optimality conditions for general decentralized stochastic dynamic optimal control problems, using a discrete-time versio…
