Some new numeric results concerning the Witsenhausen Counterexample

Optimal decentralized control with delays

“…It was shown for example by Witsenhausen that under LQG assumptions, linear compensators can be strictly suboptimal [41]. Solving for the optimal control policy for Witsenhausen's counterexample is still an active area of research [21,37]. Several related decentralized control problems were shown to be intractable due to the presence of structural constraints imposed by inter-agent communication [1].…”
