[comp.sys.apple] Compression Routines

I was jusst thinking the other day - how the heck can a whole disk be packed
down to such a miniscule size??  Then I was trying to understand the routines
involved in things like DDDeluxe and Shrinkit, and I was saying to myself "it
must take a mathematical GENIOUS to come up with these things!"  Well, I for
one would liek to learn of these types of things.  I am familiar with the
good old fashioned routine that goes like this:

1 0 0 1 1 0 goes to 01 01 02 00 02 01 01 00

that is the type that MacPaint graphics use, but sometimes that can make
compression BIGGER than the original code was.  I am just flabbergasted.  Can
anyone help here??

Always expect the least and you will never be disappointed.
