  18   Currently, the cost model uses formulas with predefined relative weights
  19   for alternative containers or container implementations.  For instance,
  20   iterating through a vector is X times faster than iterating through a list.
  21   </p><p>
  22   (Under development.)
  23   We are working on customizing this to a particular machine by providing
  24   an automated way to compute the actual relative weights for operations
  25   on the given machine.
  26   </p><p>
  27   (Under development.)
  28   We plan to provide a performance parameter database format that can be
  29   filled in either by hand or by an automated training mechanism.
  30   The analysis module will then use this database instead of the built in.
  31   generic parameters.
