Simple Compression Code Supporting Random Access and Fast String Matching
Given a sequence S of n symbols over some alphabet Σ, we develop a new compression method that is (i) very simple to implement; (ii) provides O(1) time random access to any symbol...

Pattern matching in Lempel-Ziv compressed strings: fast, simple, and deterministic
Countless variants of the Lempel-Ziv compression are widely used in many real-life applications. This paper is concerned with a natural modification of the classical pattern match...
