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 "finding a curve in a point set"):
  Abstract: Let $P$ be a polygonal curve in $\mathbb{R}^D$ of length $n$, and $S$ be a point set of size $k$. The Curve/Point Set Matching problem consists of finding a polygonal curve $Q$ on $S$ such that its Fr\'echet distance from $P$ is less than a given $\varepsilon$. In this paper, we consider this problem with the added freedom to transform the input curve $P$ by translating it, rotating it, or applying an arbitrary affine transform. We present exact and approximation algorithms for several variations of this problem.

Includes members:
  Member "computing the discrete fr echet distance in subquadratic time":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "efficient nearest neighbor query and clustering of planar curves")
  Member "hardness results on curve point set matching with frechet distance":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "applied similarity problems using frechet distance")
