MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { f(x, x) -> f(g(x), x) , g(x) -> s(x) } Obligation: innermost runtime complexity Answer: MAYBE We add following weak dependency pairs: Strict DPs: { f^#(x, x) -> c_1(f^#(g(x), x)) , g^#(x) -> c_2() } and mark the set of starting terms. We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(x, x) -> c_1(f^#(g(x), x)) , g^#(x) -> c_2() } Strict Trs: { f(x, x) -> f(g(x), x) , g(x) -> s(x) } Obligation: innermost runtime complexity Answer: MAYBE We replace rewrite rules by usable rules: Strict Usable Rules: { g(x) -> s(x) } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(x, x) -> c_1(f^#(g(x), x)) , g^#(x) -> c_2() } Strict Trs: { g(x) -> s(x) } Obligation: innermost runtime complexity Answer: MAYBE The weightgap principle applies (using the following constant growth matrix-interpretation) The following argument positions are usable: Uargs(f^#) = {1}, Uargs(c_1) = {1} TcT has computed following constructor-restricted matrix interpretation. [g](x1) = [2] [s](x1) = [1] [f^#](x1, x2) = [1] x1 + [2] [c_1](x1) = [1] x1 + [2] [g^#](x1) = [1] [c_2] = [1] This order satisfies following ordering constraints: [g(x)] = [2] > [1] = [s(x)] Further, it can be verified that all rules not oriented are covered by the weightgap condition. We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(x, x) -> c_1(f^#(g(x), x)) , g^#(x) -> c_2() } Weak Trs: { g(x) -> s(x) } Obligation: innermost runtime complexity Answer: MAYBE We estimate the number of application of {2} by applications of Pre({2}) = {}. Here rules are labeled as follows: DPs: { 1: f^#(x, x) -> c_1(f^#(g(x), x)) , 2: g^#(x) -> c_2() } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(x, x) -> c_1(f^#(g(x), x)) } Weak DPs: { g^#(x) -> c_2() } Weak Trs: { g(x) -> s(x) } Obligation: innermost runtime complexity Answer: MAYBE The following weak DPs constitute a sub-graph of the DG that is closed under successors. The DPs are removed. { g^#(x) -> c_2() } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(x, x) -> c_1(f^#(g(x), x)) } Weak Trs: { g(x) -> s(x) } Obligation: innermost runtime complexity Answer: MAYBE The input cannot be shown compatible Arrrr..
