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 "simulation problems over one counter nets"):
  Abstract: One-counter nets (OCN) are nite automata equipped with a counter that can store non-negative integer values, and that cannot be tested for zero. Equivalently, these are exactly 1-dimensional vector addition systems with states. We show that both strong and weak simulation preorder on OCN are PSPACE-complete.

Includes members:
  Member "infinite state energy games":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "energy mean payoff games")
  Member "decidability of weak simulation on one counter nets":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "shortest paths in one counter systems")
  Member "simulation over one counter nets is pspace complete":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "verification for timed automata extended with unbounded discrete data structures")
  Member "beyond language equivalence on visibly pushdown automata":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "bisimulation equivalence of first order grammars is ackermann complete")
  Member "equivalence checking on infinite state systems techniques and results":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "branching bisimilarity on normed bpa is exptime complete")
