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 "on independence domination"):
  Abstract: Let G be a graph. The independence-domination number is the maximum over all independent sets I in G of the minimal number of vertices needed to dominate I. In this paper we investigate the computational complexity of independence domination for graphs in several graph classes related to cographs. We present an exact exponential algorithm. We also present a PTAS for planar graphs.

Includes members:
  Member "known algorithms for edge clique cover are probably optimal":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "potential maximal cliques parameterized by edge clique cover")
  Member "simple linear time modular decomposition":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "the result for the grundy number on p4 classes")
