LZ differential ?

[Cyan]

Hello

As anyone heard or looked into something similar as
LZ differential, proposed by Jeremy de Bonet ?

http://www.debonet.com/Research/lzd/

The principles are well explained, but a single benchmark provided,
and unfortunately there is nothing else,
so that's really much too little.

The guy seems well above average when reading its other publications. so i don't doubt the results. However, if this was really interesting, someone else should have already noticed and re-use same principles in another algorithm ?

It seems to be delta encoding.

It's widely used.

Thanks for pointing these similarities

Still, it would be interesting to have a lzd compressor available, just for testing.
