MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { f(x) -> g(f(x)) , g(x) -> a() , g(f(x)) -> x } Obligation: innermost runtime complexity Answer: MAYBE Arguments of following rules are not normal-forms: { g(f(x)) -> x } All above mentioned rules can be savely removed. We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { f(x) -> g(f(x)) , g(x) -> a() } Obligation: innermost runtime complexity Answer: MAYBE None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'empty' failed due to the following reason: Empty strict component of the problem is NOT empty. 2) 'Best' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'WithProblem (timeout of 60 seconds)' failed due to the following reason: We add the following dependency tuples: Strict DPs: { f^#(x) -> c_1(g^#(f(x)), f^#(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) -> c_1(g^#(f(x)), f^#(x)) , g^#(x) -> c_2() } Weak Trs: { f(x) -> g(f(x)) , g(x) -> a() } Obligation: innermost runtime complexity Answer: MAYBE We estimate the number of application of {2} by applications of Pre({2}) = {1}. Here rules are labeled as follows: DPs: { 1: f^#(x) -> c_1(g^#(f(x)), f^#(x)) , 2: g^#(x) -> c_2() } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(x) -> c_1(g^#(f(x)), f^#(x)) } Weak DPs: { g^#(x) -> c_2() } Weak Trs: { f(x) -> g(f(x)) , g(x) -> a() } 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) -> c_1(g^#(f(x)), f^#(x)) } Weak Trs: { f(x) -> g(f(x)) , g(x) -> a() } 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^#(x) -> c_1(g^#(f(x)), f^#(x)) } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(x) -> c_1(f^#(x)) } Weak Trs: { f(x) -> g(f(x)) , g(x) -> a() } 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: { f^#(x) -> c_1(f^#(x)) } Obligation: innermost runtime complexity Answer: MAYBE None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'empty' failed due to the following reason: Empty strict component of the problem is NOT empty. 2) 'WithProblem' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'empty' failed due to the following reason: Empty strict component of the problem is NOT empty. 2) 'Fastest' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'Fastest (timeout of 5 seconds)' failed due to the following reason: Computation stopped due to timeout after 5.0 seconds. 2) 'WithProblem' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'empty' failed due to the following reason: Empty strict component of the problem is NOT empty. 2) 'Polynomial Path Order (PS)' failed due to the following reason: The input cannot be shown compatible 3) 'Polynomial Path Order (PS)' failed due to the following reason: The input cannot be shown compatible 2) 'Best' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'Fastest (timeout of 5 seconds) (timeout of 60 seconds)' failed due to the following reason: Computation stopped due to timeout after 5.0 seconds. 2) 'WithProblem (timeout of 30 seconds) (timeout of 60 seconds)' failed due to the following reason: The weightgap principle applies (using the following nonconstant growth matrix-interpretation) The following argument positions are usable: Uargs(g) = {1} TcT has computed the following matrix interpretation satisfying not(EDA) and not(IDA(1)). [f](x1) = [1] x1 + [7] [g](x1) = [1] x1 + [7] [a] = [6] The following symbols are considered usable {f, g} The order satisfies the following ordering constraints: [f(x)] = [1] x + [7] ? [1] x + [14] = [g(f(x))] [g(x)] = [1] x + [7] > [6] = [a()] Further, it can be verified that all rules not oriented are covered by the weightgap condition.
