Re: faster function than 1/x?

Thanks for the excellent advice! @EvanED: No, singles are fine. I avoided using f(x1) <= f(x2), because then f(x)=constant is technically a valid solution. @BedderDanu: Duh, this is a pretty obvious choice once you put it that way. I'm going to experiment with this and see how it goes. I've got to m...

faster function than 1/x?

Hey there! I have a simple program that I am optimizing. Right now one of the bottle necks is taking the inverse of each element a very large vector (1/x). I don't actually need specifically to take the inverse. All I require is a function with the following two properties: (1) f(x)>0 for all x>0 (2...

Re: Help solving number puzzle/cipher

I had the same observation as Quixote. All digits 0-9 appear somewhere. No 2 digit number occurs twice. This points away from a substitution cipher (since letters would likely occur multiple times in a 22 letter phrase) The fact that the number 3 is written as "3" and not "03" su...

Re: Cutting and rearranging a half-colored square

For another way of looking at it, what color would you say the point x=0.5 is in iteration 0? It is unclear from the statement of the problem whether this point should be red or white or something else. I think that measure hit the nail on the head. You don't even have to start subdividing. Given t...

Re: to switch or have it not matter?

I argue you do have a bit of information - specifically, whether or not the money can be divided into thirds. If I open the first box, and the amount in there is $9.01, I can infer that this is the smaller of the two (since there is no way the other box contains 1/3 of this amount), so I always swit...

My thoughts:
Spoiler:
The first image is 0
The second image somehow involves x? Though I guess its supposed to be a number. I'm pretty sure this is an x-ray of a large truck. Maybe 18 (for 18 wheeler)?
The third images is either pi^2 or pi/6
