Re: Bookmark / Pinning a problem?

To answer your original question, the Project Euler site does not currently have any specific functionality for bookmarking problems (except for "filter by solved/unsolved"). The work-around I suggested earlier of using browser bookmarks may still be viable for the cross-device use case that you des...

Re: Bookmark / Pinning a problem?

Your web browser's bookmarking facility should be adequate for this job.

Is m(1) considered 0 or 1?

I'm assuming 0 becomes you don't need any multiplication
Yes, your reasoning is correct.

ok I solved this problem...

I am really wondering tho, why H(1000), H(1 000 000), and H(100 000 000) all look so similar... Can anyone explain? feel free to send me private message.
This question would be better asked in the solutions thread for this problem on the main site.

Re: Problem 351 Visibility of extremely far away orchard

Let the middle orchard represent (0, 0). if I have say an orchard that is on the X-Axis shifted (100 000 000 - 1) away but shifted up or below by 1, -- do I assume I can see this orchard even tho the line is extremely close to just horizontal line? I am guessing all orchards are points with no widt...

Re: Problem 653

My problem that I've realised that if two particles were to move toward each other while they are an odd number of millimetres away, they would meet at a point with half-integer position ( with a .5); which seemingly goes against what the rest of the problem is implying i.e that all values are inte...

Can I PM someone to verify my result for the 21st term in the sequence given in the example for square_root(31)?
No, that is still not the purpose of this forum.

Re: Problem 090

For the purposes of this problem, an "arrangement of two cubes" means a set of two cubes, where each cube is a set of six digits. Thus your "set of sets" interpretation is correct. If two "arrangements of two cubes" are found to differ from one another only be reordering the cubes, or by reordering ...

Re: Problems with [code] statement

I think the closing tag needs to contain '/code' rather than '\code'. In the thread for problem 633 in the forum, I posted my solution: https://projecteuler.net/thread=633;page=2#316037 The problem is that the "code" token or "code=Matlab" doesn't work: the token is printed out, and the code followi...

Are we supposed to calculate every single integer set of coordinates or are the only coordinates going to be (0,r,r) and stuff like that The admissible paths (from which you are asked to find the one with the lowest risk) are permitted to use any of the integer-coordinate points on the surface of $...

I'm getting an answer, but it's not correct. However I'm able to produce the correct number when p < 10^2. Can someone confirm if the next few powers of 10 are correct?
I've removed your values from public view, but I can confirm that they were all correct.

Re: Problem 301

Ah, I see. Nevertheless, the question is correct as stated.
{0, 0, 0} is a losing triple, but it does not count towards the answer.
If people need to count it to get the correct answer, it is likely they have an off-by-one error elsewhere.

I'm happy to clarify that {0,0,0} is indeed a losing triplet. The player is "unable to move (because no stones remain)".

I expect your calculator is rounding to ten significant digits, so the fractional part has been truncated.
