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 "unfolding orthogonal polyhedra with quadratic refinement the delta unfolding algorithm"):
  Abstract: We show that every orthogonal polyhedron homeomorphic to a sphere can be unfolded without overlap while using only polynomially many (orthogonal) cuts. By contrast, the best previous such result used exponentially many cuts. More precisely, given an orthogonal polyhedron with n vertices, the algorithm cuts the polyhedron only where it is met by the grid of coordinate planes passing through the vertices, together with Theta(n^2) additional coordinate planes between every two such grid planes.

Includes members:
  Member "unfolding manhattan towers":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "unfolding genus 2 orthogonal polyhedra with linear refinement")
  Member "epsilon unfolding orthogonal polyhedra":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "unfolding polyhedra")
  Member "ununfoldable polyhedra with convex faces":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "unfolding polyhedra")
