LZW

LZW84 (Lempel-Ziv-Welch 84) je bezeztrátový kompresní algoritmus vyvinutý Abrahamem Lempelem, Jacobem Zivem a Terry Welchem. Byl publikován v roce 1984 jako vylepšení algoritmů LZ77 a LZ78 publikovaných v letech 1977 a 1978. Je relativně jednoduchý a rychlý, ale nedosahuje zdaleka tak dobré komprese jako náročnější algoritmy jako LZMA, je většinou horší…
