human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "a coinductive semantics of the unlimited register machine"):
  Abstract: We exploit (co)inductive specifications and proofs to appro ach the evaluation of low-level programs for the Unlimited Register Machine (URM)within the Coq system, a proof assistant based on the Calculus of (Co)Inductive Constructionstype theory. Our formalization allows us to certify the implementation of partial functions, thus it can be regarde d as a first step towards the development of a workbench for the formal analysis and verification of both c onverging and diverging computations.

Includes members:
  Member "using structural recursion for corecursion":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "miniagda integrating sized and dependent types")
  Member "coinductive big step operational semantics":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "program sketching with live bidirectional evaluation")

Question: Please tell me which class the source paper 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.
