Sorry, I should have mentioned that I didn't mean to use the Base64 module, I was considering writing the numbers in base 64, so that when I run out of 0-9 I go through a-z then A-Z, etc, so I use more of the bits of the characters, and use fewer digits to represent the same number.

The penalty for compression on small strings is the dictionary that gets set up for the string. If I use a fixed dictionary, this shouldn't be a problem. So I need a customized version of the compression code.

With compression, I shouldn't need to use base 64, and I'm guessing that I will get about a 60% reduction in size.

Another optimization I thought of was to change the numbers to represent the differences between the numbers instead of the numbers themselves. So instead of

1,10,45,50,120
I would have
1,9,35,5,70

It should work perfectly the first time! - toma

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
