The Context Trees of Block Sorting Compression
Abstract. The Burrows-Wheeler transform (BWT) and block sorting compression are closely related to the context trees of PPM. The usual approach of treating BWT as merely a permutat...

Multiple Pattern Matching in LZW Compressed Text
In this paper we address the problem of searching in LZW compressed text directly, and present a new algorithm for finding multiple patterns by simulating the move of the Aho-Cora...
