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 "automating resolution is np hard"):
  Abstract: We show that the problem of finding a Resolution refutation that is at most polynomially longer than a shortest one is NP-hard. In the parlance of proof complexity, Resolution is not automatizable unless P = NP. Indeed, we show it is NP-hard to distinguish between formulas that have Resolution refutations of polynomial length and those that do not have subexponential length refutations. This also implies that Resolution is not automatizable in subexponential time or quasi-polynomial time unless NP is included in SUBEXP or QP, respectively.

Includes members:
  Member "resolution lower bounds for refutation statements":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "global cardinality constraints make approximating some max 2 csps harder")
  Member "the constant inapproximability of the parameterized dominating set problem":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "trapping problem on star type graphs with applications")
  Member "narrow proofs may be maximally long":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "regular resolution for cnf of bounded incidence treewidth with few long clauses")
