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 "metric dimension parameterized by max leaf number"):
  Abstract: The metric dimension of a graph is the size of the smallest set of vertices whose distances distinguish all pairs of vertices in the graph. We show that this graph invariant may be calculated by an algorithm whose running time is linear in the input graph size, added to a function of the largest possible number of leaves in a spanning tree of the graph.

Includes members:
  Member "model checking lower bounds for simple graphs":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "simplified algorithmic metatheorems beyond mso treewidth and neighborhood diversity")
  Member "on the parameterized and approximation hardness of metric dimension":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "the fault tolerant metric dimension of cographs")
  Member "kernel bounds for path and cycle problems":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "parameterized pre coloring extension and list coloring problems")
  Member "on the complexity of metric dimension":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "the fault tolerant metric dimension of cographs")
