Absent subsequences in words
An absent factor of a string w is a string u which does not occur as a contiguous substring
(aka factor) inside w. We extend this well-studied notion and define absent subsequences: a …

Reverse-safe text indexing
We introduce the notion of reverse-safe data structures. These are data structures that
prevent the reconstruction of the data they encode (ie, they cannot be easily reversed). A …

Constructing antidictionaries of long texts in output-sensitive space
A word x that is absent from a word y is called minimal if all its proper factors occur in y.
Given a collection of k words y 1,…, yk over an alphabet Σ, we are asked to compute the set …

Substring complexity in sublinear space
Shannon's entropy is a definitive lower bound for statistical compression. Unfortunately, no
such clear measure exists for the compressibility of repetitive strings. Thus, ad hoc measures …
