- LZRW
**Lempel-Ziv Ross Williams**, (**LZRW**) refers to variants of theLZ77 lossless data compression algorithms with an emphasis on improving compression speed through the use of hash tables and other techniques. This family was explored byRoss Williams , who published a series of algorithms [*Williams, Ross. [*] beginning with LZRW1 in*http://www.ross.net/compression/lzrw1.html LZRW1*] . May 16 2005.1991 .The variants are:

* LZRW1 [

* LZRW1-A

* LZRW2

* LZRW3

* LZRW3-A

* LZRW4

* LZRW5The

LZJB algorithm is derived from LZRW1.**Notes**
