This kindof bugs me -- if you leave it stuck at a preset value, it makes it
possible to never delve into parts of solution space that have more optimal
solutions than the default seed will ever find.  Surely a random seed would
make the solution better on average over a large number of queries.

On the other hand, if the system as a whole is working well, it should not
matter what the seed is.
