We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Strict Trs: { h(x, c(y, z), t(w)) -> h(c(s(y), x), z, t(c(t(w), w))) , h(c(x, y), c(s(z), z), t(w)) -> h(z, c(y, x), t(t(c(x, c(y, t(w)))))) , h(c(s(x), c(s(0()), y)), z, t(x)) -> h(y, c(s(0()), c(x, z)), t(t(c(x, s(x))))) , t(x) -> x , t(x) -> c(0(), c(0(), c(0(), c(0(), c(0(), x))))) , t(t(x)) -> t(c(t(x), x)) } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) Arguments of following rules are not normal-forms: { h(x, c(y, z), t(w)) -> h(c(s(y), x), z, t(c(t(w), w))) , h(c(x, y), c(s(z), z), t(w)) -> h(z, c(y, x), t(t(c(x, c(y, t(w)))))) , h(c(s(x), c(s(0()), y)), z, t(x)) -> h(y, c(s(0()), c(x, z)), t(t(c(x, s(x))))) , t(t(x)) -> t(c(t(x), x)) } All above mentioned rules can be savely removed. We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Strict Trs: { t(x) -> x , t(x) -> c(0(), c(0(), c(0(), c(0(), c(0(), x))))) } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) We add the following weak dependency pairs: Strict DPs: { t^#(x) -> c_1() , t^#(x) -> c_2() } and mark the set of starting terms. We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Strict DPs: { t^#(x) -> c_1() , t^#(x) -> c_2() } Strict Trs: { t(x) -> x , t(x) -> c(0(), c(0(), c(0(), c(0(), c(0(), x))))) } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) No rule is usable, rules are removed from the input problem. We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Strict DPs: { t^#(x) -> c_1() , t^#(x) -> c_2() } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) The weightgap principle applies (using the following constant growth matrix-interpretation) The following argument positions are usable: none TcT has computed the following constructor-restricted matrix interpretation. [t^#](x1) = [1] [0] [c_1] = [0] [0] [c_2] = [0] [0] The order satisfies the following ordering constraints: [t^#(x)] = [1] [0] > [0] [0] = [c_1()] [t^#(x)] = [1] [0] > [0] [0] = [c_2()] 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 YES(O(1),O(1)). Weak DPs: { t^#(x) -> c_1() , t^#(x) -> c_2() } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) The following weak DPs constitute a sub-graph of the DG that is closed under successors. The DPs are removed. { t^#(x) -> c_1() , t^#(x) -> c_2() } We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Rules: Empty Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) Empty rules are trivially bounded Hurray, we answered YES(O(1),O(1))
