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 "phase transition for random quantified xor formulas"):
  Abstract: The QXOR-SAT problem is the quantified version of the satisfiability problem XOR-SAT in which the connective exclusive-or is used instead of the usual or. We study the phase transition associated with random QXOR-SAT instances. We give a description of this phase transition in the case of one alternation of quantifiers, thus performing an advanced practical and theoretical study on the phase transition of a quantified problem.

Includes members:
  Member "typical random 3 sat formulae and the satisfiability threshold":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "satisfiability threshold for power law random 2 sat in configuration model")
  Member "approximating the satisfiability threshold for random k xor formulas":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "lower bounds on the rate distortion function of ldgm codes")
