Details of the hypergraph:
Center node: "constant factor approximation of near linear edit distance in near linear time"
  Abstract: We show that the edit distance between two strings of length $n$ can be computed within a factor of $f(\epsilon)$ in $n^{1+\epsilon}$ time as long as the edit distance is at least $n^{1-\delta}$ for some $\delta(\epsilon) > 0$.
