Center node: "optimal control strategies in delayed sharing information structures"
  Abstract: The n-step delayed sharing information structure is investigated. This information structure comprises of K controllers that share their information with a delay of n time steps. This information structure is a link between the classical information structure, where information is shared perfectly between the controllers, and a non-classical information structure, where there is no “lateral” sharing of information among the controllers. Structural results for optimal control strategies for systems with such information structures are presented. A sequential methodology for finding the optimal strategies is also derived. The solution approach provides an insight for identifying structural results and sequential decomposition for general decentralized stochastic control problems.
