Lossless data compression algorithms: LZ77 by Abraham Lempel 1977 [1] and LZ78 by Jacob Ziv 1978 [2]. DEFLATE by Phil Katz: is a combination of the LZ77 algorithm and Huffman coding. Used by PNG and ZIP Lempel-Ziv-Welch (LZW) improved implementation of (1) and (2) published by Terry Welch 1984. Used by GIF Find out how these methods differ from run-length encoding
