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 "a commentary on breaking row and column symmetries in matrix models"):
  Abstract: The CP 2002 paper entitled "Breaking Row and Column Symmetries in Matrix Models" by Flener et al. (this https URL) describes some of the first work for identifying and analyzing row and column symmetry in matrix models and for efficiently and effectively dealing with such symmetry using static symmetry-breaking ordering constraints. This commentary provides a retrospective on that work and highlights some of the subsequent work on the topic.

Includes members:
  Member "breaking symmetry with different orderings":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "symmetries of quantified boolean formulas")
  Member "on the complexity and completeness of static constraints for breaking row and column symmetry":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "breaking symmetries in graph search with canonizing sets")
  Member "multiset ordering constraints":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "breaking symmetry with different orderings")
  Member "filtering algorithms for the multiset ordering constraint":
    also connected through other hyperedges:
      (none)
  Member "slide a useful special case of the cardpath constraint":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "classifying pattern and feature properties to get a θ n checker and reformulation for sliding time series constraints")
