Thanks for the reply, but I still maintain that my post wasn't aggressive.
I am content to stand corrected.
Why are you assuming that English isn't my first language?
You have chosen Belarus as Location. Any reason for this?

Re: Some features that are not available on this site

Hi Junglemath I don't know if you are aware that there have been severe attempts to hack Project Euler. A few years ago PE has been shut down for a few months after such an attack, in order to prevent sensitive user data (especially e-mail adresses in combination with password hashes) to be stolen. ...

Re: Problem release times

Is there a specific reason why the release times were moved from Friday/Saturday to Saturday/Sunday? Yes, assuming that the majority of people work from Monday to Friday, releasing problems on Fridays constitues a handycap for participants in America competing for the Eulerian ranks. By the earlies...

Re: Problem 503

All of your values F(n) are too big for n>4, for example F(5)=2.05 A brute force program should NOT assume any strategy, but find out which moves turn out to be optimal without preselection. Try to see which cases (trees in the game) for n=5 are omitted by your brute force program. After the brute f...

Re: Problem 257

I solved problem 257 using similar technique as the others who solved it. Then I found out missing triplets and rewrote my code completely. Now I can generate all triplets and there are more than twice the number of unique triplets than the answer says. Hi tf08rq0 It seems pretty improbable that yo...

Re: Problem 316

The problem description for 316 appears to have a typo in it. The upper limit of the summation is off to the right of the $\sum$ rather than above it: $\sum \limits_{n = 2}{999999}$. It should read $\sum \limits_{n = 2}^{999999}$ instead. Thanks, changed. (That typo must have sliped in during the l...

Re: Problem 663

I am sorry, michelebastione, in this problem we we did NOT use the word subsequence according to the wikipedia's definition, but the way it's described in the definition of $M_n(i)$ (as this would also make the problem quite trivial, since you'd only have to add all positive values of the sequence. ...

Vamsi, we are not per se opposed to people building a small, closed group working on solving problems collaboratively.
However, this forum is in no way a closed group and should not be, so we don't want you to use this forum to do so.

Re: Problem 611

No, I mean three different ways of representing a number as the sum of two squares, then the door with this number would be opened, closed and opened again, thus this number would have to be counted as well.

Please tell me. Isnt the "Numbers that are the sum of 2 distinct nonzero squares in exactly 1 way" the correct sequence for the problem ?
No, what happens when you find three different sums for one number?

Re: Problem 620

Hi Dani In particular, if I assume that all circles must be tangent, and that the points of tangency have to be a half-integer number of centimetres apart, then I get g(16,5,5,6)=0. Why is this assumption wrong? Take a close look at the illustration given, showing a valid configuration. You can see ...

Re: Problem 243

You can find a lower resilent fraction for higher denominators, the question is how big the denominator must get in order to get the resilent fraction below the given treshold for the very first time. That's no contradiction. PS: Your nickname sounds german. If english is an issue and german is fine...
