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 "game theoretical modelling of network cyber security review paper"):
  Abstract: Game theory is an established branch of mathematics that offers a rich set of mathematical tools for multi-person strategic decision making that can be used to model the interactions of decision makers in security problems who compete for limited and shared resources. This article presents a review of the literature in the area of game theoretical modelling of network/cybersecurity.

Includes members:
  Member "kidnapping model an extension of selten s game":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "game theoretical modelling of network cybersecurity")
  Member "information leakage games":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "hybrid statistical estimation of mutual information and its application to information flow")
  Member "optimizing active cyber defense":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "metrics towards measuring cyber agility")
