YES(O(1),O(n^1)) We are left with following problem, upon which TcT provides the certificate YES(O(1),O(n^1)). Strict Trs: { g(x, y) -> x , g(x, y) -> y , f(s(x), y, y) -> f(y, x, s(x)) } Obligation: innermost runtime complexity Answer: YES(O(1),O(n^1)) We use the processor 'matrix interpretation of dimension 1' to orient following rules strictly. Trs: { g(x, y) -> x , g(x, y) -> y } The induced complexity on above rules (modulo remaining rules) is YES(?,O(n^1)) . These rules are moved into the corresponding weak component(s).

[g](x1, x2) = [3] x1 + [3] x2 + [3] [f](x1, x2, x3) = [3] x1 + [1] x2 + [2] x3 + [1] [s](x1) = [1] x1 + [0] This order satisfies the following ordering constraints: [g(x, y)] = [3] x + [3] y + [3] > [1] x + [0] = [x] [g(x, y)] = [3] x + [3] y + [3] > [1] y + [0] = [y] [f(s(x), y, y)] = [3] x + [3] y + [1] >= [3] x + [3] y + [1] = [f(y, x, s(x))] We return to the main proof.
