Thanks .
Made P4 P3 and removed the link to the applet.

Vamsi, I've taken a look at your weblog. Here is something from the entry for problem 1: The solution is pretty elementary; it does not use the formula for the sum of first n terms of an arithmetic progression. This is by-design, I do not want to use any extra fancy-math when an elementary solution ...

By the way: we think most people start at problem 1.

The number of unique solvers in the range [600,750] I don't have. For some other reason I processed the solvers of problems 726 through 747 yesterday. As you know #747 is the most recent problem at the moment. The number of unique solvers with a public account for these problems is 708. That's more ...

You should have got an account recovery key last year in May.
Now you have to find back your password or the code for the 12 problems you solved in May last year.
More help we can't give to you.

@hk: Based on your interpretation of what it means to be a member of the Project Euler community, I am definitely not a member of the Project Euler community. Right, you're not any more. Good riddance. @Colin: openBook is an outsider and no member any more. Once he was but he has placed himself out...

@Colin:
Please read a previous post by openbook. https://projecteuler.chat/viewtopic.php?p=59324#p59324

The thing is simple: Project Euler considers itself a community. Members having a public, unlisted or permanently delisted account are requested not to place solutions online outside PE. If they do place solutions online outside PE they place themselves outside the community, their account is locked...

The official resource is https://projecteuler.info/.
The advantage of this resource is that it is automatically kept up to date by projecteuler.
This means recent problems and their answers, changes in problems and the news section.
Updates occur every night.

Me thinks, up till now you solved four problems today and a couple of wrong answers.

Currently we are experiencing server issues. We are distributing available slots over users. If you wait the indicated time all wiil be ok.
Yes chances are that this situation happens again.

The algoritm is a linear regression on the times it took to solve the problem for the first 100 solvers, the difficulty is derived from the slope of that regression scaled to 20 steps. Based on that information you could try to make something that reproduces the difficulty of some rather recent prob...

No.
You can sort the forum (on this board) alphabetically and none of the topics is so dramatically long as you are suggesting.

That post of mine is really a long, long time ago.

Only if you have something new to add that wasn't mentioned in the other posts. Or if you have a program in a language that isn't in the thread already.

I can't think of a clever name to use for 700.

You could have a look at this page:

You're right.
However, after the correct answer was on the site the number of correct answers grew rather fast.
The difficulty is measured as the speed of solutions not the number of them.

10 weeks after publication a problem is moved from recent problems to the archives.
At that moment a difficulty assessment is automatically calculated.
If there are less than 100 solvers the assessment is temporary.

The answer has been corrected.
Apologies for the inconvenience.
