There is a different approach to functions depending on the
modus operandi. For example, if functions are 'poisoned' then
one wants to use the fewest possible functions to achieve some
effect. If the effect is unlikely, one may have to minimize cost, or
On the other hand, if the functions are exponential, then there
might be no risk, or it might be advantageous to have expert
advice on combining functions.
If the function must be related to an existing system or function,
then it is important to 'tailor' the function to fit the existing
If the function must be utilitarian, then the focus should be on
maximizing the good effects of the function, and streamlining
implementation, with an eye towards the advantage of repeated
iterations of improvements.
Generally, the advantage is always expressed in terms of
functions of whatever type.
