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 "language asp f with arithmetic expressions and consistency restoring rules"):
  Abstract: In this paper we continue the work on our extension of Answer Set Programming by non-Herbrand functions and add to the language support for arithmetic expressions and various inequality relations over non-Herbrand functions, as well as consistency-restoring rules from CR-Prolog. We demonstrate the use of this latest version of the language in the representation of important kinds of knowledge.

Includes members:
  Member "functional answer set programming":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "an asp semantics for constraints involving conditional aggregates")
  Member "a decidable subclass of finitary programs":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "constraint answer set programming without grounding")
  Member "stable models and an alternative logic programming paradigm":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "the seventh answer set programming competition design and results")
