Re: Problem 166

Could anyone please check my code? I've tried hundreds of little variations to make it work, but alas, to no result. I've checked if for bugs countless times, and I can't see what's wrong with it.
Can I PM my code to someone?

Re: Problem 515

You're missing the second line: $d(p,n,k) = \sum^n_{i=1} d(p,i,k−1)$ (with $k\geq1$), so $d(p,n,3)=d(p,1,2)+d(p,2,2)+...+d(p,n,2)$.

Re: New Awards (10 April 2015)

Here's what the mouse-over text of CC for continued commitment says for me: blabla, Progress: 170/200 But I have solved 196 problems, as the mouse-over text of the D-award correctly shows. Also, as Jaap said: in this forum you say that C,CC and D are for any 100/200/500 problems, but their mouse-ove...

Re: Problem Solving Awards

one more thing... if you are looking at a problem, you can't see the difficulty level of that problem. Perhaps it could be incorporated in the hover text, just below the title?

Re: Errors/Warnings/Bugs

Now for me, it looks again like jpaulson said: triple LaTeX, everywhere.
Indeed, as Jaap said, the text I quoted was just [Math Processing Error] colored red, not LaTeX.

Re: Errors/Warnings/Bugs

I had this too (also on Chrome, and not just with problem 505 but with anything with LaTeX), but when I checked right now on problem 505 I got the following:
Let:

[Math Processing Error]
You are given:

[Math Processing Error]
Find [Math Processing Error].
Any idea why this might happen?

Re: Problem 159

Thanks to Wilko I discovered my mistake: while factorising all the numbers, I stopped one too early: so $961=31^2$ was seen as a prime, with mdrs(961)=7 instead mdrs(31*31)=4+4. For 1,000,000 my first answer was correct, since 1,000,000 is itself a square.

Re: Problem 159

I have checked my program multiple times, but I can't find any mistake and my answer for 1<n<1000 is 1 lower than the value given in the second post. It's not just an one-off error, since my answer for 1,000,000 isn't off by one. My code isn't very complicated, and I don't see where I'm going wrong....

Re: Problem 118

I've got a question. After looking at my Python code for some time, I have removed some bugs, but still get the red cross :(. Can I PM someone with my code, since I have no idea what I might be doing wrong. I count each set only once, so that's not the problem.

Re: Project Euler Returns

For me, the brackets in problems 81,82 and 83 don't show an image: when I go to the link of the image, I get sent to http://projecteuler.net/error. I use Chrome, but I don't think it's the browser's fault, since the link doesn't work.

Re: Problem 104

Thanks!
EDIT: I've checked again, and are the rest of the values (for first and last digits) off by one?
EDIT: The values of k when the last 9 digits are pandigital, were off by one when k was even... stupid mistake, one i++ was where it shouldn't be.

Re: Problem 104

Could someone confirm these values: for the last 9 digits, these are pandigital: F_996271,F_997031,F_998987 for the first 9 digits: F_992229,F_994961,F_997942 As first values I do get 541 and 2749, but I'm worried it's not exact enough... Also, is it true that It has six digits , because my first va...

Re: Problem 077

I've already solved this problem, but my code is just brute force. So I scanned the forum, and the first link of BjornEdstrom looked interesting. Especially the link in the third line was nice, so I tried the third type in that link, also with $c_n$. Somewhere I've made a mistake, but I don't want t...

Re: Problem 205

Is there someone I can discuss (PM) this with, because I feel like it is possible to solve it this way, but I'm making a mistake somewhere... And it would help to write it down, and probably someone does know how to do it this way.

Re: Problem 205

Yeah, I was assuming a normal distribution. I'm thinking about using binomCdf (a cumalative binomial distribution), but I'm having a few problems: first of all, I already know the $\sigma$ of six cubic dice. I could also calculate the number of dots, and the chance of each dot$\mu=n \times p: \mu=6\...

Re: Problem 205

I've got a question, about why my method doesn't work. This is the idea behind it: I calculate the $\sigma$ and the $\mu$ of the 6 cubic dices ($\sigma_6=\sqrt6\times \sigma_{1}$, $\mu_6=6 \times \mu_1$), the same with the nine pyramidal dices, then I calculate the $\sigma$ and the $\mu$ of the tota...

Re: Problem 162

After a few hours of typing in answers with only the last 4 digits wrong, I've finally solved. But I still have a few questions: How did all those people solve it? All those formula's... I've solved it like kotulek (almost exactly the same, but other language) and I don't understand what they are do...
