--------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  f(0()) -> 1()
     , f(s(x)) -> g(x, s(x))
     , g(0(), y) -> y
     , g(s(x), y) -> g(x, +(y, s(x)))
     , +(x, 0()) -> x
     , +(x, s(y)) -> s(+(x, y))
     , g(s(x), y) -> g(x, s(+(y, x)))}

Proof Output:    
  The input cannot be shown compatible
