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 "directed graph embeddings"):
  Abstract: Definitions of graph embeddings and graph minors for directed graphs are introduced. For the class of 2-terminal directed acyclic graphs (TDAGs) the definitions coincide, and the class is closed under both operations. The usefulness of the directed embedding operation is demonstrated be characterizing all TDAGs with parallel-width at most $k$, which generalizes earlier characterizations of series-parallel graphs.

Includes members:
  Member "informational braess paradox the effect of information on traffic congestion":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "signaling in bayesian network congestion games the subtle power of symmetry")
  Member "asymptotically tight bounds for inefficiency in risk averse selfish routing":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "can taxes improve congestion on all networks")
  Member "playing the wrong game smoothness bounds for congestion games with heterogeneous biases":
    also connected through other hyperedges:
      (none)
  Member "computational issues in time inconsistent planning":
    also connected through other hyperedges:

  Member "a complete anytime algorithm for treewidth":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "graph convolutional policy for solving tree decomposition via reinforcement learning heuristics")
