Answer:
  YES(O(1),O(n^2))

We use the processor 'matrix interpretation of dimension 1' to
orient following rules strictly.

Trs:
  { gcd(0(), y) -> y
  , gcd(s(x), 0()) -> s(x) }

The induced complexity on above rules (modulo remaining rules) is
YES(?,O(n^1)) . These rules are moved into the corresponding weak
component(s).

Answer:
  YES(O(1),O(n^2))

We use the processor 'matrix interpretation of dimension 1' to
orient following rules strictly.

Trs: { minus(x, 0()) -> x }

The induced complexity on above rules (modulo remaining rules) is
YES(?,O(n^1)) . These rules are moved into the corresponding weak
component(s).

We return to the main proof.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(1)).

Weak Trs:
  { le(0(), y) -> true()
  , le(s(x), 0()) -> false()
  , le(s(x), s(y)) -> le(x, y)
  , minus(x, 0()) -> x
  , 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(), s(x), s(y)) -> gcd(minus(x, y), s(y))
  , if_gcd(false(), s(x), s(y)) -> gcd(minus(y, x), s(x)) }
Obligation:
  runtime complexity
Answer:
  YES(O(1),O(1))

Empty rules are trivially bounded

Hurray, we answered YES(O(1),O(n^2))
