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 "formation games of reliable networks"):
  Abstract: We establish a network formation game for the Internet's Autonomous System (AS) interconnection topology. The game includes different types of players, accounting for the heterogeneity of ASs in the Internet. We incorporate reliability considerations in the player's utility function, and analyze static properties of the game as well as its dynamic evolution. We provide dynamic analysis of its topological quantities, and explain the prevalence of some "network motifs" in the Internet graph. We assess our predictions with real-world data.

Includes members:
  Member "network formation games with heterogeneous players and the internet structure":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "geometric network creation games")
  Member "network formation heterogeneous traffic bilateral contracting and myopic dynamics":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "strategic formation of heterogeneous networks")
