MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { ge(0(), 0()) -> true() , ge(0(), s(0())) -> false() , ge(0(), s(s(x))) -> ge(0(), s(x)) , ge(s(x), 0()) -> ge(x, 0()) , ge(s(x), s(y)) -> ge(x, y) , minus(0(), 0()) -> 0() , minus(0(), s(x)) -> minus(0(), x) , minus(s(x), 0()) -> s(minus(x, 0())) , minus(s(x), s(y)) -> minus(x, y) , plus(0(), 0()) -> 0() , plus(0(), s(x)) -> s(plus(0(), x)) , plus(s(x), y) -> s(plus(x, y)) , div(x, y) -> ify(ge(y, s(0())), x, y) , ify(true(), x, y) -> if(ge(x, y), x, y) , ify(false(), x, y) -> divByZeroError() , if(true(), x, y) -> s(div(minus(x, y), y)) , if(false(), x, y) -> 0() } 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 perSymbol-enrichment and initial automaton 'match'' failed due to the following reason: match-boundness of the problem could not be verified. 2) 'Bounds with minimal-enrichment and initial automaton 'match'' failed due to the following reason: match-boundness of the problem could not be verified.
