... the length of my strings (3k characters), and the number of elements (300) leads to prohibitive times for my search. It took a week just to check one element of the array against every other element.

Can you confirm this please. Your current method took 1 week to do 299 LCSs. Which as you have (300 * 299)/2 = 44,850 to do, this would take 150 weeks to perform the processing?

If so, I think I can help you. I believe I can get that down to 67 hours. But, as this is so much quicker (than both your current method and a couple of others I have tried), I would very much like to verify my program against some known data.

So, if you could let us/me have say 5 of your 3k strings, and the LCS that your current method finds + the time taken, I could check what I have against your findings before exposing any stupidities to the world.

TIA.

Alternatively, I could provide my test data for you to try.

The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.

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.
