MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { f(s(s(s(s(s(s(s(s(x)))))))), y, y) -> f(id(s(s(s(s(s(s(s(s(x))))))))), y, y) , id(s(x)) -> s(id(x)) , id(0()) -> 0() } Obligation: runtime complexity Answer: MAYBE None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'WithProblem (timeout of 60 seconds)' failed due to the following reason: Computation stopped due to timeout after 60.0 seconds. 2) 'Best' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'WithProblem (timeout of 30 seconds) (timeout of 60 seconds)' failed due to the following reason: Computation stopped due to timeout after 30.0 seconds. 2) 'Fastest (timeout of 5 seconds) (timeout of 60 seconds)' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'Bounds with minimal-enrichment and initial automaton 'match'' failed due to the following reason: match-boundness of the problem could not be verified. 2) 'Bounds with perSymbol-enrichment and initial automaton 'match'' failed due to the following reason: match-boundness of the problem could not be verified. 3) 'Best' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'bsearch-popstar (timeout of 60 seconds)' failed due to the following reason: The processor is inapplicable, reason: Processor only applicable for innermost runtime complexity analysis 2) 'Polynomial Path Order (PS) (timeout of 60 seconds)' failed due to the following reason: The processor is inapplicable, reason: Processor only applicable for innermost runtime complexity analysis 3) 'Innermost Weak Dependency Pairs (timeout of 60 seconds)' failed due to the following reason: We add the following weak dependency pairs: Strict DPs: { f^#(s(s(s(s(s(s(s(s(x)))))))), y, y) -> c_1(f^#(id(s(s(s(s(s(s(s(s(x))))))))), y, y)) , id^#(s(x)) -> c_2(id^#(x)) , id^#(0()) -> 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^#(s(s(s(s(s(s(s(s(x)))))))), y, y) -> c_1(f^#(id(s(s(s(s(s(s(s(s(x))))))))), y, y)) , id^#(s(x)) -> c_2(id^#(x)) , id^#(0()) -> c_3() } Strict Trs: { f(s(s(s(s(s(s(s(s(x)))))))), y, y) -> f(id(s(s(s(s(s(s(s(s(x))))))))), y, y) , id(s(x)) -> s(id(x)) , id(0()) -> 0() } Obligation: runtime complexity Answer: MAYBE We estimate the number of application of {3} by applications of Pre({3}) = {2}. Here rules are labeled as follows: DPs: { 1: f^#(s(s(s(s(s(s(s(s(x)))))))), y, y) -> c_1(f^#(id(s(s(s(s(s(s(s(s(x))))))))), y, y)) , 2: id^#(s(x)) -> c_2(id^#(x)) , 3: id^#(0()) -> c_3() } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { f^#(s(s(s(s(s(s(s(s(x)))))))), y, y) -> c_1(f^#(id(s(s(s(s(s(s(s(s(x))))))))), y, y)) , id^#(s(x)) -> c_2(id^#(x)) } Strict Trs: { f(s(s(s(s(s(s(s(s(x)))))))), y, y) -> f(id(s(s(s(s(s(s(s(s(x))))))))), y, y) , id(s(x)) -> s(id(x)) , id(0()) -> 0() } Weak DPs: { id^#(0()) -> c_3() } Obligation: runtime complexity Answer: MAYBE Empty strict component of the problem is NOT empty.
