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 "linearizable iterators for concurrent data structures"):
  Abstract: In this work, we provide a general framework for adding a linearizable iterator to data structures with set operations. We propose a condition on these set operations, called locality, so that any data structure implemented from local atomic operations can be augmented with a linearizable iterator as described by our framework. We then apply the iterator framework to various data structures, prove locality of their operations, and demonstrate that the iterator framework does not significantly affect the performance of concurrent operations.

Includes members:
  Member "range queries in non blocking k ary search trees":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "pam parallel augmented maps")
  Member "a general technique for non blocking trees":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "dynamic graph operations a consistent non blocking approach")
