Abstract

The FM index (Ferragina & Manzini, J. ACM, 2005) is a widely-used compresseddata structure that stores a string T in a compressed form that also supports fast pattern matching queries. Fixed-block boosting is a relatively straightforward technique that achieves optimal index size in theory, but to date it is unclear how best to translate the method into practice. In this paper we describe several new techniques for implementing fixed-block boosting efficiently. The new indexes are consistently fast and small relative to the state-of-the-art, and thus make a good 'off-the-shelf' choice for most applications.
