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: { f(g(x)) -> g(g(f(x))) , f(g(x)) -> g(g(g(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: { f(g(x)) -> g(g(f(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). [f](x1) = [3] x1 + [0] [g](x1) = [1] x1 + [2] This order satisfies the following ordering constraints: [f(g(x))] = [3] x + [6] > [3] x + [4] = [g(g(f(x)))] [f(g(x))] = [3] x + [6] >= [1] x + [6] = [g(g(g(x)))] We return to the main proof.
