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 "computing the frechet distance of trees and graphs of bounded tree width"):
  Abstract: We give algorithms to compute the Frechet distance of trees and graphs with bounded tree width. Our algorithms run in $O(n^2)$ time for trees of bounded degree, and $O(n^2\sqrt{n \log n})$ time for trees of arbitrary degree. For graphs of bounded tree width we show one can compute the Frechet distance in FPT (fixed parameter tractable) time.

Includes members:
  Member "an improved isomorphism test for bounded tree width graphs":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "hypergraph isomorphism for groups with restricted composition factors")
  Member "fixed parameter tractable canonization and isomorphism test for graphs of bounded treewidth":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "graph isomorphism in quasipolynomial time parameterized by treewidth")
  Member "can we compute the similarity between surfaces":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "tighter connections between formula sat and shaving logs")
