Abstract: The Lempel Ziv Algorithm is an algorithm for lossless data compression. It is not a single algorithm, but a whole family of algorithms, stemming from the two algorithms proposed by Jacob Ziv and Abraham Lem-pel in their landmark papers in 1977 and 1978. Lempel Ziv algorithms are widely used in compression utilities such as gzip, GIF image compression and the V.42 modem standard. Figure 1: The Lempel Ziv Algorithm Family This report shows how the two original Lempel Ziv algorithms, LZ77 and LZ78, work and also presents and compares several of the algorithms that have been derived from the original Lempel Ziv algorithms.

A universal algorithm for sequential data compression
Jacob Ziv,A. Lempel +1 more
TL;DR: The compression ratio achieved by the proposed universal code uniformly approaches the lower bounds on the compression ratios attainable by block-to-variable codes and variable- to-block codes designed to match a completely specified source.
Compression of individual sequences via variable-rate coding
Jacob Ziv,A. Lempel +1 more
TL;DR: The proposed concept of compressibility is shown to play a role analogous to that of entropy in classical information theory where one deals with probabilistic ensembles of sequences rather than with individual sequences.
