I used a genetic algorithm that tries to find the best solution
possible in a given number of iterations.  It doesn't always find the
best, but generally does pretty well.  And because there are
randomized aspects to each run, you can end up with different
solutions (of different scores) on consecutive runs.  The code can be
found at:
