MAYBE

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

Strict Trs:
  { minus(x, 0()) -> x
  , minus(s(x), s(y)) -> minus(x, y)
  , quot(0(), s(y)) -> 0()
  , quot(s(x), s(y)) -> s(quot(minus(x, y), s(y)))
  , le(0(), y) -> true()
  , le(s(x), 0()) -> false()
  , le(s(x), s(y)) -> le(x, y)
  , inc(0()) -> s(0())
  , inc(s(x)) -> s(inc(x))
  , log(x) -> logIter(x, 0())
  , logIter(x, y) ->
    if(le(s(0()), x), le(s(s(0())), x), quot(x, s(s(0()))), inc(y))
  , if(true(), true(), x, y) -> logIter(x, y)
  , if(true(), false(), x, s(y)) -> y
  , if(false(), b, x, y) -> logZeroError() }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

The input cannot be shown compatible

Arrrr..
