Deterministic Sparse Suffix Sorting in the Restore Model (1509.07417v2)

Published 24 Sep 2015 in cs.DS

Abstract: Given a text $T$ of length $n$, we propose a deterministic online algorithm computing the sparse suffix array and the sparse longest common prefix array of $T$ in $O(c \sqrt{\lg n} + m \lg m \lg n \lg* n)$ time with $O(m)$ words of space under the premise that the space of $T$ is rewritable, where $m \le n$ is the number of suffixes to be sorted (provided online and arbitrarily), and $c$ is the number of characters with $m \le c \le n$ that must be compared for distinguishing the designated suffixes.
