 Mar30 revised Average case complexity for checking if list is sorted deleted 11 characters in body Mar30 comment Average case complexity for checking if list is sorted Thank you; that is very helpful! I wish I could have seen it myself, but I am glad to know that I was on the right track :) Mar30 accepted Average case complexity for checking if list is sorted Mar30 revised Average case complexity for checking if list is sorted added 217 characters in body Mar30 revised Average case complexity for checking if list is sorted added 45 characters in body Mar30 asked Average case complexity for checking if list is sorted Oct1 accepted Evaluate $\lim_{h\to 0^+} \frac{e^{-\frac{1}{h}}}{h}$ Oct1 comment Evaluate $\lim_{h\to 0^+} \frac{e^{-\frac{1}{h}}}{h}$ Thanks, Yuval! Very nice. Is there any way to show this without relying on l'Hôpital's rule though?

Aug26 awarded Commentator Aug26 comment Is the relation $a\mathrel R b \iff f(a) \equiv f(b)$ an equivalence relation? Thank you for laying out the proof, Robert. I am wondering if there is a mathematical term/concept for the property "inheritance" observed here? Aug26 comment Is the relation $a\mathrel R b \iff f(a) \equiv f(b)$ an equivalence relation? @NajibIdrissi e.g., not a stochastic function. In this context it is redundant; apologies for the confusion. Aug26 awarded Student Aug26 comment Is the relation $a\mathrel R b \iff f(a) \equiv f(b)$ an equivalence relation? Thanks @AndresCaicedo, but I do not follow 100%. Can you please expand a bit (specifically on the suggested exercise)?
