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 "funseqset towards a purely functional data structure for the linearisation case of dynamic trees problem"):
  Abstract: Dynamic trees, originally described by Sleator and Tarjan, have been studied deeply for non persistent structures providing $\mathcal{O}(\log n)$ time for update and lookup operations as shown in theory and practice by Werneck. However, discussions on how the most common dynamic trees operations (i.e. link and cut) are computed over a purely functional data structure have not been studied. Even more, asking whether vertices $u$ and $v$ are connected (i.e. within the same forest) assumes that corresponding indices or locations for $u$ and $v$ are taken for granted in most of the literature, and not performed as part of the whole computation for such a question. We present FunSeqSet, based on the primitive version of finger trees, i.e. the de facto sequence data structure for the purely functional programming language Haskell, augmented with variants of the collection (i.e. sets) data structures in order to manage efficiently $k$-ary trees for the linearisation case of the dynamic trees problem. Different implementations are discussed, and the performance is measured.
