MAYBE 'epo* (timeout of 60.0 seconds)' -------------------------------- Answer: MAYBE Input Problem: innermost runtime-complexity with respect to Rules: { first(0(), X) -> nil() , first(s(X), cons(Y, Z)) -> cons(Y, n__first(X, activate(Z))) , from(X) -> cons(X, n__from(s(X))) , first(X1, X2) -> n__first(X1, X2) , from(X) -> n__from(X) , activate(n__first(X1, X2)) -> first(X1, X2) , activate(n__from(X)) -> from(X) , activate(X) -> X} Proof Output: The input cannot be shown compatible
