Suffix array is a data structure that can be used to index a large text file so that queries of its content can be answered quickly. Basically a suffix array is an array of all suffixes of the text in the lexicographic order. Whether or not a word occurs in the text can be answered in logarithmic time by binary search over the suffix array.

Compressed Compact Suffix Arrays
2004The compact suffix array (CSA) is a space-efficient full-text index, which is fast in practice to search for patterns in a static text. Compared to other compressed suffix arrays (Grossi and Vitter, Sadakane, Ferragina and Manzini), the CSA is significantly larger (2.7 times the text size, as opposed to 0.6–0.8 of compressed suffix arrays).

Surprisingly enough, it is not yet known how to build directly a suffix array that indexes just the k positions at word-boundaries of a text T[1, n], taking O(n) time and O(k) space in addition to T. We propose a class-note solution to this problem that achieves such optimal time and space bounds.

The suffix tree is one of the oldest full-text inverted indexes and one of the most persistent subjects of study in the theory of algorithms. With extensions and refinements, including succinct and compressed variants that provide some of its expressive power in smaller space, it constitutes a fundamental conceptual tool in the design of string ...

Gapped suffix arrays (also known as bi-factor arrays) were recently presented for approximate searching under the Hamming distance. These structures can be used to find occurrences of a pattern P, where the characters inside a gap do not have to match. This paper describes a succinct representation of gapped suffix arrays.

Computing all Repeats Using Suffix Arrays
2003We describe an algorithm that identifies all the repeating substrings (tandem, overlapping, and split) in a given string $x = x[1...n]$. Given the suffix arrays of $x$ and of the reversed string $\hat{x}$, the algorithm requires $\Theta(n)$ time for its execution and represents its output in $\Theta(n)$ space, either as a reduced suffix array ...

Suffix cactus: A cross between suffix tree and suffix array
1995The suffix cactus is a new alternative to the suffix tree and the suffix array as an index of large static texts. Its size and its performance in searches lies between those of the suffix tree and the suffix array. Structurally, the suffix cactus can be seen either as a compact variation of the suffix tree or as an augmented suffix array.
