1. sequence compression ?

I am looking for a method to compress/decompress a sequence of 32bit integers
that has the highest compression ratio in Euphoria

Thanks Bernie

2. Re: sequence compression ?

Are you looking to compress just sequences? or maybe whole files? there are a
few different ways
to go about compressing data once the intent is specified. I've found that
Huffman compression
works well on large text files, yielding results of 40% - 60%, but there are
others out there,
just search for 'compression' in the Archive.

Greg:

I'am just talking about sequences.
I know about the compression routine files in archive.

Ok, another question... do you want compress the length of a sequence, or the
acutal memory size
(in bytes)?

Greg:

I want to shrink the sequence to it's smallest length but have
an alglorithm to restore it as I poke the integers into memory.

Thanks

Jordah:

  I modified my eru.ex file to use your binary.e and
  when I used your code to compress resource files
  the resulting file size was 205,013 with the method
  that I'am already currently using; the resulting
  file size is 93,960; so I did not gain any better
  compression from your binary.e.
  But that could be because you are compressing Objects and
  I am only concerned with a sequence compression.
  
Thank You for your response,
Bernie
