TIMEOUT

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

Strict Trs:
  { exp(x, 0()) -> s(0())
  , exp(x, s(y)) -> *(x, exp(x, y))
  , *(0(), y) -> 0()
  , *(s(x), y) -> +(y, *(x, y))
  , -(x, 0()) -> x
  , -(0(), y) -> 0()
  , -(s(x), s(y)) -> -(x, y) }
Obligation:
  innermost runtime complexity
Answer:
  TIMEOUT

Computation stopped due to timeout after 10.0 seconds.

Arrrr..
