We are left with following problem, upon which TcT provides the certificate YES(O(1),O(n^1)). Strict Trs: { g(f(x), y) -> f(h(x, y)) , h(x, y) -> g(x, f(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: { g(f(x), y) -> f(h(x, y)) , h(x, y) -> g(x, f(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). Sub-proof: ---------- The following argument positions are usable: Uargs(f) = {1} TcT has computed the following constructor-based matrix interpretation satisfying not(EDA). [g](x1, x2) = [2] x1 + [1] [f](x1) = [1] x1 + [4] [h](x1, x2) = [2] x1 + [4] The order satisfies the following ordering constraints: [g(f(x), y)] = [2] x + [9] > [2] x + [8] = [f(h(x, y))] [h(x, y)] = [2] x + [4] > [2] x + [1] = [g(x, f(y))] 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: { g(f(x), y) -> f(h(x, y)) , h(x, y) -> g(x, f(y)) } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) Empty rules are trivially bounded Hurray, we answered YES(O(1),O(n^1))
