Thanks to all the contributors so far. What I seem to be sensing it that my idea wasn't too bad (hooray!), and if I try with different starting conditions, and occasionally allow "unfavourable" moves (as described by itub), I might be close to the right track. (Although see my response to dragonchild above, where I ponder whether simple distance travelled might be a good enough scoring mechanism for me.)

In my simplistic mind, the genetic algorithm solution sounds like a more complex method of roughly the same approach. (Although I need to investigate this further, really.)

I haven't really got my head around the suggested ILP approach, to be frank, but I can look into this further.

For the record, I'm talking of hundreds of sales reps in hundreds of locations, so I don't think the brute force method won't work with the computing power I have available.

Also for the record, I'm not required to find the optimum solution to a situation - merely a good one!

Thanks again, all,
SmugX

P.S. Incidentally, I'm by no means a regular on perlmonks - certainly not as much as I'd like to be - but I'm always so impressed by everyone's knowledge, helpfulness and courtesy. You're all great. Have a drink on me.

P.P.S. I'm just kidding about the drink.

• 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.
