Hi guys,

I was planning on making a Compressor/De-compressor with the Lempel-Ziv-Welch alogarithm. I've been looking around the internet for some implications and noticed that they're really long when making a the compressor alone. Does anyone know a simple code so I can understand it? A simple compressor and decompressor using LZW alogarithm. I plan on using textfiles first :)

*this isn't a home work. I'm just trying to get a broader view of these things.

:) I implemented that algorithm as the final project. I would share it but unfortunately it was very long time ago and I lost it (possibly somewhere in a CD). maybe you know, but the idea is to construct a dictionary for binary sequences. use short key for a long repeating series, and add new key (longest) for a new sequence. (or something like that :))

If you want some code to play with, search for past CP articles.
