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 in succinct one counter games"):
  Abstract: We consider the reachability problem on transition systems corresponding to succinct one-counter machines, that is, machines where the counter is incremented or decremented by a value given in binary.

Includes members:
  Member "on the complexity of counter reachability games":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "reachability games with relaxed energy constraints")
  Member "reachability in two clock timed automata is pspace complete":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "life is random time is not markov decision processes with window objectives")
  Member "the complexity of robot games on the integer line":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "quantitative aspects of programming languages and systems over the past 2 4 years and beyond")
  Member "reachability games on extended vector addition systems with states":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "energy mean payoff games")
