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 "dynamic 3 sided planar range queries with expected doubly logarithmic time"):
  Abstract: This work studies the problem of 2-dimensional searching for the 3-sided range query of the form $[a, b]\times (-\infty, c]$ in both main and external memory, by considering a variety of input distributions. We present three sets of solutions each of which examines the 3-sided problem in both RAM and I/O model respectively. The presented data structures are deterministic and the expectation is with respect to the input distribution.

Includes members:
  Member "i o efficient data structures for colored range and prefix reporting":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "partial sums on the ultra wide word ram")
  Member "dynamic ordered sets with exponential search trees":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "improved dynamic graph coloring")
