MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { h(x, y) -> f(x, y, x) , f(0(), 1(), x) -> h(x, x) , g(x, y) -> x , g(x, y) -> y } Obligation: innermost runtime complexity Answer: MAYBE We add following weak dependency pairs: Strict DPs: { h^#(x, y) -> c_1(f^#(x, y, x)) , f^#(0(), 1(), x) -> c_2(h^#(x, x)) , g^#(x, y) -> c_3() , g^#(x, y) -> c_4() } and mark the set of starting terms. We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { h^#(x, y) -> c_1(f^#(x, y, x)) , f^#(0(), 1(), x) -> c_2(h^#(x, x)) , g^#(x, y) -> c_3() , g^#(x, y) -> c_4() } Strict Trs: { h(x, y) -> f(x, y, x) , f(0(), 1(), x) -> h(x, x) , g(x, y) -> x , g(x, y) -> y } Obligation: innermost runtime complexity Answer: MAYBE No rule is usable, rules are removed from the input problem. We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { h^#(x, y) -> c_1(f^#(x, y, x)) , f^#(0(), 1(), x) -> c_2(h^#(x, x)) , g^#(x, y) -> c_3() , g^#(x, y) -> c_4() } Obligation: innermost runtime complexity Answer: MAYBE The weightgap principle applies (using the following constant growth matrix-interpretation) The following argument positions are usable: Uargs(c_1) = {1}, Uargs(c_2) = {1} TcT has computed following constructor-restricted matrix interpretation. [0] = [2] [1] = [1] [h^#](x1, x2) = [1] x1 + [1] [c_1](x1) = [1] x1 + [1] [f^#](x1, x2, x3) = [1] x3 + [2] [c_2](x1) = [1] x1 + [2] [g^#](x1, x2) = [2] [c_3] = [1] [c_4] = [1] This order satisfies following ordering constraints: 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: { h^#(x, y) -> c_1(f^#(x, y, x)) , f^#(0(), 1(), x) -> c_2(h^#(x, x)) } Weak DPs: { g^#(x, y) -> c_3() , g^#(x, y) -> c_4() } 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, y) -> c_3() , g^#(x, y) -> c_4() } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { h^#(x, y) -> c_1(f^#(x, y, x)) , f^#(0(), 1(), x) -> c_2(h^#(x, x)) } Obligation: innermost runtime complexity Answer: MAYBE The input cannot be shown compatible Arrrr..
