MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { gt(s(x), s(y)) -> gt(x, y) , gt(s(x), 0()) -> true() , gt(0(), y) -> false() , divides(x, y) -> div(x, y, y) , div(s(x), s(y), z) -> div(x, y, z) , div(s(x), 0(), s(z)) -> div(s(x), s(z), s(z)) , div(0(), s(x), z) -> false() , div(0(), 0(), z) -> true() , prime(x) -> test(x, s(s(0()))) , test(x, y) -> if1(gt(x, y), x, y) , if1(true(), x, y) -> if2(divides(x, y), x, y) , if1(false(), x, y) -> true() , if2(true(), x, y) -> false() , if2(false(), x, y) -> test(x, s(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) 'bsearch-popstar (timeout of 60 seconds)' failed due to the following reason: The input cannot be shown compatible 2) 'Polynomial Path Order (PS) (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.
