### 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...

### Re: Problem 656

No, that is still not the purpose of this forum.

As Animus said, "it is not appropiate to ask for help for recent problems that have not even reached 100 solvers".

### 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 ...

To be clear: 'squaring' a matrix refers specifically to matrix multiplication of a matrix with itself.

### 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 $...

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?

### Re: Problem 301

Ah, I see. Nevertheless, the question is correct as stated.

{0, 0, 0} is a losing triple, but it does

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)".

### Re: problem 206

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

### Re: why are hints for solutions not allowed?

Project Euler's approach has always been "If you can't solve it, you can't solve it", which is why PE does not provide an open forum for discussing solution methods.

You may be interested in this thread, in which a tangentially related point was discussed.

### Re: Problem 493

This is indeed the correct forum for discussing issues with understanding the wording of a problem. The problem only talks about the number of distinct colours in the draw. So, whether the balls have any other distinguishing marks (aside from their colour) is irrelevant. The order of the draw (and w...
