Data structures and algorithms for the string statistics problem. (English) Zbl 0846.68023
Summary: Given a textstring \(x\) of length \(n\), the minimal augmented suffix tree \(\widehat T(x)\) of \(x\) is a digital-search index that returns, for any query string \(w\) and in a number of comparisons bounded by the length of \(w\), the maximum number of nonoverlapping occurrences of \(w\) in \(x\). It is shown that, denoting the length of \(x\) by \(n\), \(\widehat T(x)\) can be built in time \(O(n\log^2 n)\) and space \(O(n\log n)\), off-line on a RAM.
