ST compression

ST is mainly built for high compression with some focus on run time speed. PPM is the algorithm of choice used in development.


Usage:

ST <e|d> [switch] <Inputfilename> <Outputfilename>

e: encode
d: decode

Switches
-n - normal compression
-f - fast compression
-b - best compression


2GB RAM
x86 compatible CPU


 ST 0.8
 ST 0.75
 ST 0.7
 ST 0.6
 ST 0.56
 ST 0.51

	I would like to thank my teachers for their insights and continuing support.
	Thanks for the large collection of papers maintained at compression.ru
	Thanks to Matt Mahoney of mattmahoney.net for including version 0.5.1 of ST in his Large Text Compression Benchmark.
