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: "connection matrices and the definability of graph parameters"
  Abstract: In this paper we extend and prove in detail the Finite Rank Theorem for#N#connection matrices of graph parameters definable in Monadic Second Order Logic#N#with counting (CMSOL) from B. Godlin, T. Kotek and J.A. Makowsky (2008) and#N#J.A. Makowsky (2009). We demonstrate its vast applicability in simplifying#N#known and new non-definability results of graph properties and finding new#N#non-definability results for graph parameters. We also prove a Feferman-Vaught#N#Theorem for the logic CFOL, First Order Logic with the modular counting#N#quantifiers.

Connected through hyperedge HE-1 (induced by source paper "efficient computation of generalized ising polynomials on graphs with fixed clique width"):
  with members:
    - "complexity of ising polynomials"
    - "on the complexity of the interlace polynomial"

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.
