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. ...

Re: Problem 656

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...

Re: Inconsistency on Project Eulers problems forum

I think a nice addition to the forum would be an ability to see a persons original name somewhere near his post. Maybe under his current name or maybe like it is done in the leaderboards. I am not sure I get your point. It is true that the user name pops up in the fastest solver table as (part of t...

hi, tamandua The parameter $k$ does not restrict the number of piles in the starting position nor the number of piles present after a valid move, only the number of piles a single pile may be split into. Therefore is {1,1,1,2} a valid starting position for a game with $k=2$, and happens to be a winn...
