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: { add(0(), x) -> x , add(s(x), y) -> s(add(x, y)) } 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: { add(0(), x) -> 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). Sub-proof: ---------- TcT has computed the following constructor-based matrix interpretation satisfying not(EDA). [add](x1, x2) = [2] x1 + [3] x2 + [0] [0] = [2] [s](x1) = [1] x1 + [0] This order satisfies the following ordering constraints: [add(0(), x)] = [3] x + [4] > [1] x + [0] = [x] [add(s(x), y)] = [2] x + [3] y + [0] >= [2] x + [3] y + [0] = [s(add(x, y))] We return to the main proof.
