   I would set Seed per default. Even worse than a bad query path
   is an unpredictable query path. I see no argument, that a random Seed
   would buy us anything.

   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.
