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: "translation based constraint answer set solving"
  Abstract: We solve constraint satisfaction problems through translation to answer set programming (ASP). Our reformulations have the property that unit-propagation in the ASP solver achieves well defined local consistency properties like arc, bound and range consistency. Experiments demonstrate the computational value of this approach.

Connected through hyperedge HE-1 (induced by source paper "sat vs csp a commentary"):
  with members:
    - "a translational approach to constraint answer set solving"
    - "decomposition of the nvalue constraint"
    - "circuit complexity and decompositions of global constraints"
    - "decompositions of all different global cardinality and related constraints"

Connected through hyperedge HE-2 (induced by source paper "predicate logic as a modelling language the idp system"):
  with members:
    - "lazy model expansion interleaving grounding with search"
    - "the third open answer set programming competition"
    - "an enhanced features extractor for a portfolio of constraint solvers"
    - "asp modulo csp the clingcon system"
