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 "translating between wavelet tree and wavelet matrix construction"):
  Abstract: The wavelet tree (Grossi et al. [SODA, 2003]) and wavelet matrix (Claude et al. [Inf. Syst., 2015]) are compact data structures with many applications such as text indexing or computational geometry. By continuing the recent research of Fischer et al. [ALENEX, 2018], we explore the similarities and differences of these heavily related data structures with focus on their construction. We develop a data structure to modify construction algorithms for either the wavelet tree or matrix to construct instead the other. This modification is efficient, in that it does not worsen the asymptotic time and space requirements of any known wavelet tree or wavelet matrix construction algorithm.

Includes members:
  Member "simple fast and lightweight parallel wavelet tree construction":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "improved parallel construction of wavelet trees and rank select structures")
  Member "wavelet trees meet suffix trees":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "string synchronizing sets sublinear time bwt construction and optimal lce data structure")
