MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { f(0(), 1(), x) -> f(h(x), h(x), x) , h(0()) -> 0() , h(g(x, y)) -> y } Obligation: innermost runtime complexity Answer: MAYBE We add following dependency tuples: Strict DPs: { f^#(0(), 1(), x) -> c_1(f^#(h(x), h(x), x), h^#(x), h^#(x)) , h^#(0()) -> c_2() , h^#(g(x, y)) -> c_3() } and mark the set of starting terms. We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(0(), 1(), x) -> c_1(f^#(h(x), h(x), x), h^#(x), h^#(x)) , h^#(0()) -> c_2() , h^#(g(x, y)) -> c_3() } Weak Trs: { f(0(), 1(), x) -> f(h(x), h(x), x) , h(0()) -> 0() , h(g(x, y)) -> y } Obligation: innermost runtime complexity Answer: MAYBE We estimate the number of application of {2,3} by applications of Pre({2,3}) = {1}. Here rules are labeled as follows: DPs: { 1: f^#(0(), 1(), x) -> c_1(f^#(h(x), h(x), x), h^#(x), h^#(x)) , 2: h^#(0()) -> c_2() , 3: h^#(g(x, y)) -> c_3() } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(0(), 1(), x) -> c_1(f^#(h(x), h(x), x), h^#(x), h^#(x)) } Weak DPs: { h^#(0()) -> c_2() , h^#(g(x, y)) -> c_3() } Weak Trs: { f(0(), 1(), x) -> f(h(x), h(x), x) , h(0()) -> 0() , h(g(x, y)) -> y } 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. { h^#(0()) -> c_2() , h^#(g(x, y)) -> c_3() } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(0(), 1(), x) -> c_1(f^#(h(x), h(x), x), h^#(x), h^#(x)) } Weak Trs: { f(0(), 1(), x) -> f(h(x), h(x), x) , h(0()) -> 0() , h(g(x, y)) -> y } Obligation: innermost runtime complexity Answer: MAYBE Due to missing edges in the dependency-graph, the right-hand sides of following rules could be simplified: { f^#(0(), 1(), x) -> c_1(f^#(h(x), h(x), x), h^#(x), h^#(x)) } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(0(), 1(), x) -> c_1(f^#(h(x), h(x), x)) } Weak Trs: { f(0(), 1(), x) -> f(h(x), h(x), x) , h(0()) -> 0() , h(g(x, y)) -> y } Obligation: innermost runtime complexity Answer: MAYBE We replace rewrite rules by usable rules: Weak Usable Rules: { h(0()) -> 0() , h(g(x, y)) -> y } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(0(), 1(), x) -> c_1(f^#(h(x), h(x), x)) } Weak Trs: { h(0()) -> 0() , h(g(x, y)) -> y } Obligation: innermost runtime complexity Answer: MAYBE The input cannot be shown compatible Arrrr..
