TIMEOUT

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

Strict Trs:
  { le(0(), y) -> true()
  , le(s(x), 0()) -> false()
  , le(s(x), s(y)) -> le(x, y)
  , minus(x, 0()) -> x
  , minus(0(), x) -> 0()
  , minus(s(x), s(y)) -> minus(x, y)
  , gcd(0(), y) -> y
  , gcd(s(x), 0()) -> s(x)
  , gcd(s(x), s(y)) -> if_gcd(le(y, x), s(x), s(y))
  , if_gcd(true(), x, y) -> gcd(minus(x, y), y)
  , if_gcd(false(), x, y) -> gcd(minus(y, x), x) }
Obligation:
  innermost runtime complexity
Answer:
  TIMEOUT

Computation stopped due to timeout after 10.0 seconds.

Arrrr..
