Strict Trs: { f(x, y, s(z)) -> s(f(0(), 1(), z)) , f(0(), 1(), x) -> f(s(x), x, x) } Obligation: 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, y, s(z)) -> s(f(0(), 1(), z)) } 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(s) = {1} TcT has computed the following constructor-based matrix interpretation satisfying not(EDA). [f](x1, x2, x3) = [4] x3 + [1] [0] = [0] [1] = [0] [s](x1) = [1] x1 + [2] The following symbols are considered usable {f} The order satisfies the following ordering constraints: [f(x, y, s(z))] = [4] z + [9] > [4] z + [3] = [s(f(0(), 1(), z))] [f(0(), 1(), x)] = [4] x + [1] >= [4] x + [1] = [f(s(x), x, x)] We return to the main proof.
