MAYBE

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

Strict Trs:
  { ge(x, 0()) -> true()
  , ge(0(), s(x)) -> false()
  , ge(s(x), s(y)) -> ge(x, y)
  , minus(x, 0()) -> x
  , minus(s(x), s(y)) -> minus(x, y)
  , div(x, y) -> ify(ge(y, s(0())), x, y)
  , ify(true(), x, y) -> if(ge(x, y), x, y)
  , ify(false(), x, y) -> divByZeroError()
  , if(true(), x, y) -> s(div(minus(x, y), y))
  , if(false(), x, y) -> 0() }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

The input cannot be shown compatible

Arrrr..
