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 "optimal multibinding unification for sharing and linearity analysis"):
  Abstract: In the analysis of logic programs, abstract domains for detecting sharing properties are widely used. Recently the new domain ShLin ! has been introduced to generalize both sharing and linearity information. This domain is endowed with an optimal abstract operator for single-binding unication. The authors claim that the repeated application of this operator is also optimal for multi-binding unication. This is the proof of such a claim.

Includes members:
  Member "on the interaction between sharing and linearity":
    also connected through other hyperedges:
      (none)
  Member "optimality in goal dependent analysis of sharing":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "on the interaction between sharing and linearity")
  Member "enhanced sharing analysis techniques a comprehensive evaluation":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on the interaction between sharing and linearity")

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.
