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 "reachability for branching concurrent stochastic games"):
  Abstract: We give polynomial time algorithms for deciding almost-sure and limit-sure reachability in Branching Concurrent Stochastic Games (BCSGs). These are a class of infinite-state imperfect-information stochastic games that generalize both finite-state concurrent stochastic reachability games, as well as branching simple stochastic reachability games.

Includes members:

    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "xpl an extended probabilistic logic for probabilistic transition systems")
