论文摘要
考虑一个文本$ t [1..n] $由参考序列$ r = t [1 .. \ ell] $前缀。我们展示了如何给定$ r $和$ z'$ - 短语相对Lempel-Ziv parse $ t [\ ell + 1..n] $的$ t [\ ell + 1..n] $,对于$ r $,我们可以构建$ n \,\ mathrm {polylog}(polylog}(polylog}(n)$ o(n)$ o(n)$ o(n)$ o(n)$ o($ o(el)$ o(el e el + z'),我们可以构建$ t $ $ t $的lz77 parse。
Consider a text $T [1..n]$ prefixed by a reference sequence $R = T [1..\ell]$. We show how, given $R$ and the $z'$-phrase relative Lempel-Ziv parse of $T [\ell + 1..n]$ with respect to $R$, we can build the LZ77 parse of $T$ in $n\,\mathrm{polylog} (n)$ time and $O (\ell + z')$ total space.
