regards, My name is putu budayasa, I study at a university in
Indonesia, I read your notes about lzip. can i make your notes as a
reference for my thesis?, whether you are having other notes about
LZMA because I wanted to take a topic about LZMA method, and Can you
explain algorithm or how to work this LZMA.
Of course you may use my notes as a reference.
About other notes, you may find interesting to read LZMA's talk page in
the Wikipedia
http://en.wikipedia.org/wiki/Talk:Lempel%E2%80%93Ziv%E2%80%93Markov_chain_algorithm
Explaining in detail how LZMA works is not easy. If you really want to
understand how it works I recommend you the following sequence:
First, study the decompression code in lzip. This code illustrates the
structure of the LZMA stream.
http://www.sfr-fresh.com/unix/misc/lzip-1.11-rc5.tar.gz:a/lzip-1.11-rc5/decoder.h
http://www.sfr-fresh.com/unix/misc/lzip-1.11-rc5.tar.gz:a/lzip-1.11-rc5/decoder.cc
Then study the compression code in lzip. This code shows how LZMA tries
to find the optimal values to encode but is much simpler than the
original LZMA code by Igor Pavlov.
And last, you can see the full LZMA code from Pavlov himself shipped
with pdlzip.

Best regards,
Antonio.
