متن کاملReplacing suffix trees with enhanced suffix arrays
The suffix tree is one of the most important data structures in string processing and comparative genomics. However, the space consumption of the suffix tree is a bottleneck in large scale applications such as genome analysis. In this article, we will overcome this obstacle. We will show how every algorithm that uses a suffix tree as data structure can systematically be replaced with an algorit...

متن کاملWavelet Trees Meet Suffix Trees
We present an improved wavelet tree construction algorithm and discuss its applications to a number of rank/select problems for integer keys and strings. Given a string of length n over an alphabet of size σ ≤ n, our method builds the wavelet tree in O(n log σ/ √ logn) time, improving upon the state-of-the-art algorithm by a factor of √ log n. As a consequence, given an array of n integers we c...
