Re: Adding a task from Project Euler on SPOJ

I am already the author of some tasks on SPOJ that are near (some kind of extension) of some questions here. I intended to be respectful to great work here at project Euler, where I learned so. Some examples: 1) Pell Fourth can be seen as an extension of 66 . project Euler is credited.This challenge...

Re: Problem 421

@Euler : on my browser http://projecteuler.net/problems;page=9, the last line shows (at this time) 85 solvers for PE421, but on fastest solver rank list, there are 86 people, and there's no sk7 (nor popeye, ...) in the list.

Re: Problem 421

I think there's still a bug in the ranking page.
At this time 70 solvers shown in the page of 401-450 problems, but 71 in rank list.
There's a 1 offset since some days, I thought it will be fixed, but as I see it again, I share.
It's not very important.

Re: Problem 421

Perhaps, it is possible to find in /tmp, some correct answers and manually give back the "honor" to first solvers. It's not a problem for me as I solved it much later... and it's true sometimes things goes wrong... PE stay for me a very high quality place. It's always a pleasure to solve one (when I...

Re: Posting solutions outside of Project Euler's site

But for one person who's able to solve a recent one (even an "easy"), it should be a formality of some hours to solve 50 problems. After that "check", He can play only with recent ones. But I understand your argument. another possibility : 4) Solve 50 problems before being able to submit for the las...

Re: Posting solutions outside of Project Euler's site

And what about : 1) to solve a 400+ problem, you need to have solved 50 problems or more. (or another bound) 2) to solve problem N, you need to have solved int(N*0.125) problems or more. 3) something else This could prevent suspect accounts. I remember there were some limitations when I create my ac...

Sorry for the late response.....but guess what.....I dug deeper.....although we got different results, looks like we both are correct (as far as the problem statement is concerned) because, for certain larger instances of the problem the answer is not unique......my old code provides only the lower...

I didn't check x/y, I use P and Q, sorry, but even in this case, I don't get 39 digits. Here is first ones, and I'll delete them in a few times, not to spoil if it is. 10³ → 36 digits : 63872... 10⁴ → 210 digits : 23611... 10⁵ → 722 digits : 29995... 10⁶ → 2472 digits : 14152...

Re: Have you written a program to write a program?

I wrote a program in python in order to unroll my 210-whell sieve of Eratosthenes, the result was a thousands line program, that is my fastest sieve in python for bound greater than 10⁹. In C, my fastest sieve is not a 210-whell. I wrote a program in python in order to write (in C or in python) a fu...

Re: Problem 066

Yes, the value exceeds 64-bit range, it's a 38-digit number. Can somebody confirm this, please? I was so sure my code was correct, but the max value it's finding is 30 digits long, and the value for D is not being accepted. Thanks! The largest minimal x has 39 digits.

Is it a loop or a fixed point ?
Don't you think there's others fixed point ?
Find them is an interesting problem.

Re: Problem 078

Just so I am not beating a really wrong bush, the problem statement "Find the least value of n for which p(n) is divisible by one million." really means that there is a p(n) = k x 10^6, where k is a (potentially large) integer... I know its stupid, but I can't get my head around a partition number ...

Could it be that the chosen setup does not scal...
