Optimized succinct data structures for massive data

  title={Optimized succinct data structures for massive data},
  author={Simon Gog and Matthias Petri},
  journal={Softw., Pract. Exper.},
Succinct data structures provide the same functionality as their corresponding traditional data structure in compact space. We improve on functions rank and select , which are the basic building blocks of FM-indexes and other succinct data structures. First, we present a cache-optimal, uncompressed bitvector representation which outperforms all existing approaches. Next, we improve — in both space and time — on a recent result by Navarro and Providel on compressed bitvectors. Last we show… CONTINUE READING
