( #3333=superdoc: print w/replies, xml ) Need Help??

Your problem is very similar to protein sequence homology searches. A protein can be represented as nothing more than a string from an alphabet of 20 letters. Sequence homology searches (which are crucial to biology and bioinformatics) basically attempt to find and score similarities between two or more such sequences.

Various algorithms exist to do this e.g. Needleman and Wunsch (Journal of Molecular Biology 48 pp443) and the ever popular BLAST www.ncbi.nlm.nih.gov/blast Of course these solutions are designed for molecular biology and would require a lot of work to alter them to handle general strings. My guess is you are looking for a simpler solution...

Use:  <p> text here (a paragraph) </p>

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.
