Private & Common Information States in Decentralized Team Equilibrium via Dynamic Programming for POMDPs with Delayed Sharing
Charalambos D. Charalambous, Umarbek Guvercin, Seddik Djouadi
Witsenhausen, in his seminal 1971 paper [1], introduced decentralized partially observable Markov decision problems (POMDPs), with multiple agents or controls operating under T-ste…

Private and Common Information States in Decentralized Parallel Dynamic Programming for Delayed Sharing Patterns
Charalambos D. Charalambous, Umarbek Guvercin, Seddik Djouadi

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…
