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 "unshuffling fields in data formats"):
  Abstract: Data format reverse engineering commonly involves identifying conserved format motifs. However, this process typically requires establishing a common ordering for format elements across instances, particularly for formats using type-(length)-value tuples or "chunk" encoding. It is useful to \emph{unshuffle} chunks with common length statistics as a precursor to identifying conserved internal structures. We formalize the unshuffling problem and subsequently derive probabilistic bounds and outline corresponding algorithms for it. We empirically demonstrate unshuffling and highlight connections with the related class of synchronization problems.

Includes members:
  Member "de bruijn entropy and string similarity":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "the geometry of syntax and semantics for directed file transformations")
  Member "multireference alignment using semidefinite programming":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "synchronisation of partial multi matchings via non negative factorisations")
