In this case, a heuristic like "less parameters, less operators and less function calls" covers all the cases.

It doesn't, because we might consider different outputs "simple" depending on what we're going to do next.

Sure, an example would be nice.

Examples in TFA and at least one in the thread. Or say 4-quadrant atan might be simpler or less simple than 2-quadrant atan, depending on what you're doing next. Lots of stuff like that. Is a factored polynomial simpler than unfactored?
