MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { inc(Cons(x, xs)) -> Cons(Cons(Nil(), Nil()), inc(xs)) , inc(Nil()) -> Cons(Nil(), Nil()) , nestinc(Cons(x, xs)) -> nestinc(inc(Cons(x, xs))) , nestinc(Nil()) -> number17(Nil()) , number17(x) -> Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Cons(Nil(), Nil()))))))))))))))))) , goal(x) -> nestinc(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) '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) 'Fastest (timeout of 5 seconds) (timeout of 60 seconds)' failed due to the following reason: Computation stopped due to timeout after 5.0 seconds. 3) '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 Arrrr..
