MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { minus(s(x), y) -> if(gt(s(x), y), x, y) , if(true(), x, y) -> s(minus(x, y)) , if(false(), x, y) -> 0() , gt(s(x), s(y)) -> gt(x, y) , gt(s(x), 0()) -> true() , gt(0(), y) -> false() , gcd(x, y) -> if1(ge(x, y), x, y) , if1(true(), x, y) -> if2(gt(y, 0()), x, y) , if1(false(), x, y) -> if3(gt(x, 0()), x, y) , ge(x, 0()) -> true() , ge(s(x), s(y)) -> ge(x, y) , ge(0(), s(x)) -> false() , if2(true(), x, y) -> gcd(minus(x, y), y) , if2(false(), x, y) -> x , if3(true(), x, y) -> gcd(x, minus(y, x)) , if3(false(), x, y) -> y } 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: 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) 'Best' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'Polynomial Path Order (PS) (timeout of 60 seconds)' failed due to the following reason: The input cannot be shown compatible 2) 'bsearch-popstar (timeout of 60 seconds)' failed due to the following reason: The input cannot be shown compatible 3) '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.
