MAYBE 'Pop* (timeout of 60.0 seconds)' -------------------------------- Answer: MAYBE Input Problem: innermost runtime-complexity with respect to Rules: { a__2nd(cons(X, cons(Y, Z))) -> mark(Y) , a__from(X) -> cons(mark(X), from(s(X))) , mark(2nd(X)) -> a__2nd(mark(X)) , mark(from(X)) -> a__from(mark(X)) , mark(cons(X1, X2)) -> cons(mark(X1), X2) , mark(s(X)) -> s(mark(X)) , a__2nd(X) -> 2nd(X) , a__from(X) -> from(X)} Proof Output: The input cannot be shown compatible
