Constant-factor approximation of near-linear edit distance in near-linear time
Joshua Brakensiek, Aviad Rubinstein·2019-04-11·via cs.DS updates on arXiv.org
We show that the edit distance between two strings of length $n$ can be computed within a factor of $f(ε)$ in $n^{1+ε}$ time as long as the edit distance is at least $n^{1-δ}$ for some $δ(ε) > 0$.
