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 "symmetry breaking constraints recent results"):
  Abstract: Symmetry is an important problem in many combinatorial problems. One way of dealing with symmetry is to add constraints that eliminate symmetric solutions. We survey recent results in this area, focusing especially on two common and useful cases: symmetry breaking constraints for row and column symmetry, and symmetry breaking constraints for eliminating value symmetry

Includes members:
  Member "the alldifferent constraint with precedences":
    also connected through other hyperedges:
      (none)
  Member "on the complexity and completeness of static constraints for breaking row and column symmetry":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a commentary on breaking row and column symmetries in matrix models")
