MAYBE

We are left with following problem, upon which TcT provides the
certificate MAYBE.

Strict Trs:
  { f(0()) -> 1()
  , f(s(x)) -> g(f(x))
  , f(s(x)) -> +(f(x), s(f(x)))
  , g(x) -> +(x, s(x)) }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

The input cannot be shown compatible

Arrrr..
