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(x, x) -> a() , f(g(x), y) -> f(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: { f(x, x) -> a() , f(g(x), y) -> f(x, 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: ---------- TcT has computed the following constructor-based matrix interpretation satisfying not(EDA). [f](x1, x2) = [1] x1 + [3] x2 + [3] [a] = [1] [g](x1) = [1] x1 + [3] This order satisfies the following ordering constraints: [f(x, x)] = [4] x + [3] > [1] = [a()] [f(g(x), y)] = [1] x + [3] y + [6] > [1] x + [3] y + [3] = [f(x, 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: { f(x, x) -> a() , f(g(x), y) -> f(x, 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))
