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 "approximation schemes for partitioning convex decomposition and surface approximation"):
  Abstract: We revisit two NP-hard geometric partitioning problems - convex decomposition and surface approximation. Building on recent developments in geometric separators, we present quasi-polynomial time algorithms for these problems with improved approximation guarantees.

Includes members:
  Member "qptas for geometric set cover problems via optimal separators":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "optimal parameterized algorithms for planar facility location problems using voronoi diagrams")
  Member "quasi polynomial time approximation scheme for sparse subsets of polygons":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "efficient approximation schemes for uniform cost clustering problems in planar graphs")
  Member "a qptas for maximum weight independent set of polygons with polylogarithmically many vertices":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "quasi polynomial time approximation schemes for packing and covering problems in planar graphs")
  Member "approximation schemes for maximum weight independent set of rectangles":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "independent sets of dynamic rectangles algorithms and experiments")
  Member "computing homotopic shortest paths efficiently":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "homotopic curve shortening and the affine curve shortening flow")
