Consistent with what? Your expectations? The standard? Some fundamental
laws?
For some consistency means that optimization never affects the results,
but language standards generally allow non-deterministic results when
it comes to fpt, so two results can be formally equivalent (they are
both arbitrary selections from a common set), even though they are
different.
