The algorithm works by replacing repeated occurrences of data with references to a single copy of that data existing earlier in the uncompressed data stream. The LZ77 algorithm operates on a buffer ...

This repository contains a Java implementation of the LZ-77 data compression algorithm. LZ-77 is a lossless data compression method that replaces repetitive sequences of characters with references to ...

Abstract: Consider the case where consecutive blocks of N letters of a semi-infinite individual sequence X over a finite alphabet are being compressed into binary sequences by some one-to-one mapping.

Abstract: The longest match strategy in LZ77, a major bottleneck in the compression process, is accelerated in enhanced algorithms such as LZ4 and ZSTD by using a hash table. However, it may results ...

Grammar compression is, next to Lempel-Ziv (LZ77) and run-length Burrows-Wheeler transform (RLBWT), one of the most flexible approaches to representing and processing highly compressible strings. The ...
