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 "robust proximity search for balls using sublinear space"):
  Abstract: Given a set of n disjoint balls b1, . . ., bn in IRd, we provide a data structure, of near linear size, that can answer (1 \pm \epsilon)-approximate kth-nearest neighbor queries in O(log n + 1/\epsilon^d) time, where k and \epsilon are provided at query time. If k and \epsilon are provided in advance, we provide a data structure to answer such queries, that requires (roughly) O(n/k) space; that is, the data structure has sublinear space requirement if k is sufficiently large.

Includes members:
  Member "approximating minimization diagrams and generalized proximity search":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "resolving sinr queries in a dynamic setting")
  Member "down the rabbit hole robust proximity search and density estimation in sublinear space":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "lower bounds for k distance approximation")
