No.  Adjusting a rule is entirely different from adjusting a number.
The adjustment of a number merely explores a space.  A number spectrum
does specify/describe a metric.  So, for example, adjusting an integer
with particular boundaries for the model, say [-10, 100] provides a
well-defined space.

The adjustment of a rule, however, doesn't _necessarily_ assume any such
space or metric, which is why we have to back off to the more flexible
word "measure".

The methods used for search and optimization are different when
exploring ill-formed "spaces" versus well-formed spaces.  And it's
important to point this out in order to be clear about one's research,
especially to an audience that may not be expert in modeling and simulation.
