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 "practical evaluation of lempel ziv 78 and lempel ziv welch tries"):
  Abstract: We present the first thorough practical study of the Lempel-Ziv-78 and the Lempel-Ziv-Welch computation based on trie data structures. With a careful selection of trie representations we can beat well-tuned popular trie data structures like Judy, m-Bonsai or Cedar.

Includes members:
  Member "dynamic space efficient hashing":
    also connected through other hyperedges:
      (none)
  Member "compression with the tudocomp framework":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "bidirectional text compression in external memory")
  Member "faster 64 bit universal hashing using carry less multiplications":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "fast hashing with strong concentration bounds")
