 Jun 28 comment search on a split data structure BTW, $b(n)$ is $n$ for the unsorted list as you always need to look at all elements before concluding it isn't there. Jun 28 comment Special representation of a number The remarkable resemblance of the two plots is interesting though, and I'm curious what the general shape (of the "upper" and "lower" curves) are. Jun 28 comment search on a split data structure It still wasn't clear so I've edited the question; take a look and see if that's what you intended. Jun 28 revised search on a split data structure quote Jun 28 comment search on a split data structure Can you edit the question to make it clearer in the formatting which parts are quotation from the test / homework / question, and which parts are your own thoughts / questions? Jun 26 comment How many algebras are there of finite-sized $\Omega$? I just got a notification because this answer was upvoted. Not only do I have no recollection of having posted this answer, I don't even understand it now. At all. Clearly the explanation could have been better! Jun 26 comment Expectation value of number of drawings of increasing sequences of labelled balls from an urn. @uomoinverde The bounty doesn't matter so much; what would be gratifying would be if you indicated that you understood the ideas better now. :-) Jun 26 comment Expectation value of number of drawings of increasing sequences of labelled balls from an urn. Note that the question asks for the probability that the number of drawings is greater than $k$, but you seem to be calculating $\Pr(X \ge k)$ instead of $\Pr(X > k)$ (which is what it asks for).

Jun 18 comment How to determine growth rate of coefficients of generating function @Michael Yes, their Chapter VIII on the saddle-point method covers such generating functions.

Why attempt 19? Apr 15 comment Maximizing profit (dynamic programming) Guess you need to first read about dynamic programming before solving exercises. Did you manage to solve all (or most) of questions 1 to 18, before attempting question 19? Apr 14 awarded Nice Answer Mar 22 comment Is this 5th root in the set of natural numbers? What have you tried? What leads you to the belief that no such $x$ exists? If you include that in your question you are more likely to get an answer. Mar 8 comment “What if” math joke: the derivative of $\ln(x)^e$ @bcrist: Ah I see... I was wrong, thanks for that! Mar 7 comment “What if” math joke: the derivative of $\ln(x)^e$ @bcrist: Ah good point; perhaps one should say that though the What-If series contains references to the XKCD comics, there is none in the other direction. (Sort of how I can make references to a TV show, but a TV show will never make references to me.) At any rate, the subject of this question definitely doesn't count as "an xkcd", whatever that means. Nor is it even a joke, IMO.
