MAYBE 'Pop* with parameter subtitution (timeout of 60.0 seconds)' ----------------------------------------------------------- Answer: MAYBE Input Problem: innermost runtime-complexity with respect to Rules: { incr(nil()) -> nil() , incr(cons(X, L)) -> cons(s(X), incr(L)) , adx(nil()) -> nil() , adx(cons(X, L)) -> incr(cons(X, adx(L))) , nats() -> adx(zeros()) , zeros() -> cons(0(), zeros()) , head(cons(X, L)) -> X , tail(cons(X, L)) -> L} Proof Output: The input cannot be shown compatible
