### Re: A puzzle

Thanks for the introduction to RoseCode (and WeChall)!! Well, speaking of WeChall there is a similar challenge that can be solved with pencil and paper but it is really a challenge to solve it that way (I myself had to write some piece of code): WeChall Sudoku Challenge And problem setter says that...

### A puzzle

I was asked this by a friend and he wanted me find a solution only. Working on it by using pencil and paper, I found more than one solutions. So I thought I could turn it into a fun problem. Well I did and released it here: Rosecode problem 314 Seems like finding all the solutions by using pencil an...

Here's a link to a challenge based on this method for those who might want to give it a try:pj6444 wrote:There are RSA attack methods that use continued fractions. For example: https://en.wikipedia.org/wiki/Wiener%27s_attack

### Rosecode math challenges (and more)

Hi All,

We are a group people adding/solving some math problems also here. I believe we have some interesting problems (near PE quality) in math&programming category.

I'd like to invite you at least to have a look: here

Cheers.

### Re: Physics site like Project Euler?

Check this one out:

http://www.right-answer.net/

A substantial percentage of the probems are of that kind.

### Re: Mathalon Ownership

I got a mail from Hemant Verma (fameoflight) He wrote : I am working on restoring it. But it might take some time. One week. I had received the same mail but it's almost 4 months since then and there is no indication that it will come back. In the mean time, we have found another meeting place: Sev...

### Re: Mathalon Ownership

Mathalon seems to be gone. Hemant's attitude is odd.

He doesn't reply to any e-mails. The other day I checked his linkedin profile and the following day he checked mine. So he's alive but not responding to anybody.

### Re: Problem 210

Well, you're absolutely right re: diamond, but you'll see that something subtle happens with regards to forming the triangle. I don't want to take away the joy of discovery from you, but the smallest example that shows the errant behavior starts @ r=24. Do a brute-force of the coordinate space & co...

### Re: Problem 210

What does |x| + |y| ≤ r mean? It should define a diamond shaped area, right? I don't understand what kind of trap did you fall into? I have found a closed formula that seems to work for small number without writing any code, then what happens? I have a feeling from the messages in this thread that t...

### Re: Problem 241

Yes this one seems to be a hard one but there are 10 to 20 problems I spent more time to solve than this one. I had found an effective algo on the first day. I even tried to do it by hand (later I checked that I had found 50% of the numbers by hand) then I switched to coding which took most of my ti...

### Re: "Ambiguous Numbers" is ambiguous

This discussion has helped me solve it. I had suspected that I should have included the trivial ones but not sure. After being sure, it was a quick fix.

### Re: Problem 195

You have two problems. Before you turn your attention to making it faster, you should read the problem text once again carefully. You overlooked something there - apart from that, your code is correct (and therefore deleted from your post), albeit very slow. Oh yes. I have read it again. OK. I know...

### Re: Problem 195

Hi, I am also working on this problem but I cannot find T(100)=1234. My brute force attack always gives more results than 1234. For example I am curious if the following findings with a very small one side and 2 comparably much longer sides are included in this number: a=163, b=19927, c=20008 a=165,...
