ANNOUNCING LZRW1
================
I have developed  a fast text compression algorithm  called lzrw1. The
algorithm compresses about 10% worse  than Unix compress but runs four
times faster. The  algorithm is not patented and will  not be patented
and to the best of my knowledge is not covered by any patents as it is
a LZ77  class algorithm. A  paper describing the algorithm  appears in
the proceedings of the data compression  conference held in Utah a few
weeks ago:

IEEE/NASA Data Compression Conference April 8-1, 1991, Snowbird, Utah.
"An Extremely Fast Ziv-Lempel Data Compression Algorithm"
by R.N.Williams, p.362-371.

C and 68000 code for the algorithm is available by ftp access:

Machine: sirius.itd.adelaide.edu.au
Directory: pub/misc
Files: lzrw1.c   and   lzrw1.68000

The 68000  code takes about 13  instructions per byte to  compress and
about 4 instructions per byte to decompress.

Enjoy,

Ross Williams.
