MAYBE 'epo* (timeout of 60.0 seconds)' -------------------------------- Answer: MAYBE Input Problem: innermost runtime-complexity with respect to Rules: { isList(nil()) -> tt() , isList(Cons(x, xs)) -> isList(xs) , downfrom(0()) -> nil() , downfrom(s(x)) -> Cons(s(x), downfrom(x)) , f(x) -> cond(isList(downfrom(x)), s(x)) , cond(tt(), x) -> f(x)} Proof Output: The input cannot be shown compatible
