MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { a__nats() -> a__adx(a__zeros()) , a__nats() -> nats() , a__adx(X) -> adx(X) , a__adx(cons(X, Y)) -> a__incr(cons(X, adx(Y))) , a__zeros() -> cons(0(), zeros()) , a__zeros() -> zeros() , a__incr(X) -> incr(X) , a__incr(cons(X, Y)) -> cons(s(X), incr(Y)) , a__hd(X) -> hd(X) , a__hd(cons(X, Y)) -> mark(X) , mark(cons(X1, X2)) -> cons(X1, X2) , mark(0()) -> 0() , mark(zeros()) -> a__zeros() , mark(s(X)) -> s(X) , mark(incr(X)) -> a__incr(mark(X)) , mark(adx(X)) -> a__adx(mark(X)) , mark(nats()) -> a__nats() , mark(hd(X)) -> a__hd(mark(X)) , mark(tl(X)) -> a__tl(mark(X)) , a__tl(X) -> tl(X) , a__tl(cons(X, Y)) -> mark(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) '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..
