One of my other examples for Algorithm::Genetic is redoing one of the best nodes, Genetic Programming or breeding Perls, using my module. This node uses bits of legal perl code like "$x += $y;" and "$y=$x;" to make up a long operation; the bits are breed and mutated such that the operation, when evals to a number, and the GA aims to make code that matched a given number. This is a much better GA example, since with a good operations set, there's numerous ways to calculate a given number.

The reason this JAPH one works is that I upped the mutation rate to 10%, such that when it's close but not at the solution, there's a good chance that that one character pertubation is the right one to lock in the right solution.

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 or How to display code and escape characters are good places to start.
