MAYBE

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

Strict Trs:
  { le(0(), y) -> true()
  , le(s(x), 0()) -> false()
  , le(s(x), s(y)) -> le(x, y)
  , minus(0(), y) -> 0()
  , minus(s(x), y) -> if_minus(le(s(x), y), s(x), y)
  , if_minus(true(), s(x), y) -> 0()
  , if_minus(false(), s(x), y) -> s(minus(x, y))
  , quot(0(), s(y)) -> 0()
  , quot(s(x), s(y)) -> s(quot(minus(x, y), s(y)))
  , log(s(0())) -> 0()
  , log(s(s(x))) -> s(log(s(quot(x, s(s(0())))))) }

  innermost runtime complexity
Answer:
  MAYBE

The input cannot be shown compatible

Arrrr..
