human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "on the controller synthesis problem for distributed systems with causal memory"
  Abstract: The decidability of the distributed version of the Ramadge and Wonham controller synthesis problem#R##N#where both the plant and the controllers are modelled as Zielonka automata#R##N#and the controllers have causal memory#R##N#is a challenging open problem.#R##N#There exists three classes of plants for which the existence of a correct controller with causal memory has been shown decidable: when the dependency graph of actions is series-parallel, #R##N#when the processes are connectedly communicating and when the dependency graph of processes is a tree. #R##N#We provide a unified proof of these three results,#R##N#and design a class of plants, called broadcast games, #R##N#with a decidable controller synthesis problem.#R##N#This leads to new examples of decidable architectures.

Connected through hyperedge HE-1 (induced by source paper "a class of zielonka automata with a decidable controller synthesis problem"):
  with members:
    - "automated synthesis of distributed controllers"
    - "distributed synthesis for acyclic architectures"
    - "asynchronous games over tree architectures"

The 40 classes are: cs.NA(Numerical Analysis), cs.MM(Multimedia), cs.LO(Logic in Computer Science), cs.CY(Computers and Society), cs.CR(Cryptography and Security), cs.DC(Distributed, Parallel, and Cluster Computing), cs.HC(Human-Computer Interaction), cs.CE(Computational Engineering, Finance, and Science), cs.NI(Networking and Internet Architecture), cs.CC(Computational Complexity), cs.AI(Artificial Intelligence), cs.MA(Multiagent Systems), cs.GL(General Literature), cs.NE(Neural and Evolutionary Computing), cs.SC(Symbolic Computation), cs.AR(Hardware Architecture), cs.CV(Computer Vision and Pattern Recognition), cs.GR(Graphics), cs.ET(Emerging Technologies), cs.SY(Systems and Control), cs.CG(Computational Geometry), cs.OH(Other Computer Science), cs.PL(Programming Languages), cs.SE(Software Engineering), cs.LG(Machine Learning), cs.SD(Sound), cs.SI(Social and Information Networks), cs.RO(Robotics), cs.IT(Information Theory), cs.PF(Performance), cs.CL(Computation and Language), cs.IR(Information Retrieval), cs.MS(Mathematical Software), cs.FL(Formal Languages and Automata Theory), cs.DS(Data Structures and Algorithms), cs.OS(Operating Systems), cs.GT(Computer Science and Game Theory), cs.DB(Databases), cs.DL(Digital Libraries), cs.DM(Discrete Mathematics). Directly output the class name.
