human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "finding points in general position"
  Abstract: We study computational aspects of the General Position Subset Selection problem defined as follows: Given a set of points in the plane, find a maximum-cardinality subset of points in general position. We prove that General Position Subset Selection is NP-hard, APX-hard, and give several fixed-parameter tractability results.

Connected through hyperedge HE-1 (induced by source paper "computational complexity aspects of point visibility graphs"):
  with members:
    - "on colouring point visibility graphs"
    - "recognition and complexity of point visibility graphs"
    - "some results on point visibility graphs"
    - "unsolved problems in visibility graphs of points segments and polygons"

Connected through hyperedge HE-2 (induced by source paper "a practical algorithm for enumerating collinear points"):
  with members:
    - "point line cover the easy kernel is essentially tight"

Connected through hyperedge HE-3 (induced by source paper "an improved lower bound for general position subset selection"):
  with members:
    - "point line cover the easy kernel is essentially tight"
