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 note on the longest common substring with k mismatches problem"):
  Abstract: The recently introduced longest common substring with $k$-mismatches ($k$-LCF) problem is to find, given two sequences $S_1$ and $S_2$ of length $n$ each, a longest substring $A_1$ of $S_1$ and $A_2$ of $S_2$ such that the Hamming distance between $A_1$ and $A_2$ is at most $k$. So far, the only subquadratic time result for this problem was known for $k = 1$~\cite{FGKU2014}. We first present two output-dependent algorithms solving the $k$-LCF problem and show that for $k = O(\log^{1-\varepsilon} n)$, where $\varepsilon > 0$, at least one of them works in subquadratic time, using $O(n)$ words of space. The choice of one of these two algorithms to be applied for a given input can be done after linear time and space preprocessing. Finally we present a tabulation-based algorithm working, in its range of applicability, in $O(n^2\log\min(k+\ell_0, \sigma)/\log n)$ time, where $\ell_0$ is the length of the standard longest common substring.
