The "iterative graph" link may state this or you may have already considered this, but I seem to remember from an Operations Research class some 20 years ago something called the Law of Large Numbers: When you have to come up with a very good solution to a problem with a huge solution space, but not necessarily the optimal solution, generating roughly 30 solutions has something like a 90% chance of one of the solutions being among the top 5 or 10% of all possible solutions.

Thus, with your lottery approach and a consistent way of scoring the solution (weighted criteria), the highest scoring solution among 30 that you can generate will just (most likely) BE one of the very best solutions you could possibly generate. Not the optimal solution but an extremely good one. (Even if there are 436,357,219,651 possible solutions. A statistician could provide details. :-)

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.
