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: "generating single peaked votes"
  Abstract: We discuss how to generate singled peaked votes uniformly from the Impartial Culture model.

Connected through hyperedge HE-1 (induced by source paper "individual based stability in hedonic diversity games"):
  with members:
    - "convergence and hardness of strategic schelling segregation"
    - "schelling games on graphs"
    - "hedonic diversity games"
    - "on the likelihood of single peaked preferences"
    - "fractional hedonic games"
    - "eliciting single peaked preferences using comparison queries"

Connected through hyperedge HE-2 (induced by source paper "equilibria under the probabilistic serial rule"):
  with members:
    - "manipulating the probabilistic serial rule"
    - "allocation of divisible goods under lexicographic preferences"
    - "fair assignment of indivisible objects under ordinal preferences"
    - "the computational complexity of random serial dictatorship"

Question: Please tell me which class the center node belongs to. 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.
