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 "a load buffer semantics for total store ordering"):
  Abstract: We address the problem of verifying safety properties of concurrent programs running over the Total Store Order (TSO) memory model. Known decision procedures for this model are based on complex enc ...

Includes members:
  Member "stateless model checking for power":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "dynamic verification with observational equivalence of c c concurrency")
  Member "stateless model checking for tso and pso":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "dynamic verification with observational equivalence of c c concurrency")
  Member "robustness against power is pspace complete":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "checking robustness against snapshot isolation")
  Member "herding cats modelling simulation testing and data mining for weak memory":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "realitycheck bringing modularity hierarchy and abstraction to automated microarchitectural memory consistency verification")
