1.) I think it is bad to start with Problem #1 . This problem was most difficult. 2.) It took me a while to understand what was exactly meant by T:= . After I understood that I could undertsnad the example given with numleaves. To make this problem more transperent I would give an example e.g. T : 0 / / / / \ \ \ 0 0 0 0 0 0 0 T1 T2 T3 T4 T5 T6 T7 => T= with Ti= {<>} 3.) Problem 1b) This problem can only be solved if somebody gets a) correclty. Thus if somebody makes a mistake in a , the person almost automatically lost all the points in B because he/she wont find a solution and willl wast a lot of time . Is there maybe another induction that we can do ? 4.) Problem 2b) The problme is hard to understand. First, I would change the following text: Assuming (unrealistically) that $g$ could be arbitrarily large, give the least real number, $k$, such that $p(g) = O(g^k)$, or explain why there is no such $k$. Assuming (unrealistically) that $g$ could be arbitrarily large argue for one of the following two cases: - there exists a least real number $k$ such that $p(g) = O(g^k)$, - no real number $k$ exists such that $p(g) = O(g^k)$. ------------------- Having said that I still do not fully understand the question. In a p is not defined by a function but a minimum border p \geq \frac{dR^{g+n-1}(R-1)}{R^n - 1}. Thus with everything fixed but g the bound above can be defined as p > f(g). Thus, even if f would be a constant function we still have no upper bound for p and thus p can never be in O(*) . Problem 3 ) I think that should be the starting problem - it is fairly easy Problem 4d) the phrase "Bottomless Pits of Utter Annihilation" was confusing for me . I know you want to make it fun but I do not know what Utter Annihilation means. Problem 4e) I think you should change the names of your creates to more commen names . I personally do not know what a netwts is , and I believe a lot of other students wont know what a toads is. Additonally you define slugs as small s and the possible number of sets as capital S . Can we have fourth letter for the sets that is not related in any way to the other three ? It might be ocnfusing for the students and confusing for us to grade ! I agree with Ching that I find 4e a little bit wiered. Problem 5b) why should students mark all leaves where sally is happy with an H. It is rather confusing because it is so obvious which once they are . I though for a second if I did not get something bc it seemed to trivial . This quiz feels a lot shorter than the first quiz . I finshed it in 65 minutes.
