P-1 Stats Website!!!
Well, after a lot of digging, I have gone through all the missions ever done by mersenne-aries and sorted them all out. I have also started to post the stats on my website.


Now, please keep in mind that this my first ever attempt to create a website, so please go easy on me.

I have started this thread as a spin-off of the "missions" thread. The main things that I woud like to be posted in this thread are

1) Suggestions for things to be added to the website
2) Things on the website that need to be fixed
3) etc

There are a few problems with it at the moment (the major one being that there is very little information on it).

1) Some people aren't in the "top p-1ers yet" due to "complications" but I will put them in there ASAP. These people are....
call apple
cold fury

2)koekie is in the "everyone's largest factor twice". I will fix this.

3) none of the pages have a "back to home page" yet. I will try to do this. However getting more stats is probably a higher priority at the moment.

This are the problems that I already know about and plan to fix. Any suggestions/bugs/problems, just post them here and i will try to fix them as soon as I can.

Oh, most people are in there using their primenet user name, if you would rather have it changed to your forum name or something else, just let me know.

Ok, I just did a mojor update. Well..... it was a major update in my view anyways...

Things that have been changed

1) koekie now only appears once in "largest factor found by each person"
2) all those people that were missed out in the initial "top p-1ers" should be there.
3) In the "top p-1ers" it now shows their largest factor and the exponent that it is a factor of
4) you can now click on names in "top p-1ers" and it will take you to a new page where it shows all the factors that they have found since the beginning of mersenne-aries
5) every page (that is not the index page) should contain a link to take you back to the homepage.

Could everyone that has done p-1 work, please check their stats and make sure they are correct. I know that you won't know [I]exactly[/I], but if my website says that you have done 50 p-1s and you know that you have done over 200, then let me know and I will see what I did wrong.

If you would like another name other than your "primenet user name", just let me know. However, I would prefer it if it was still a name where everyone knows that it is them. For example, S130260 is James Heinrich. So in that sort of case it would be good to change the name because no one knows him as S130260.

So, what else needs to be changed/added/deleated from the website. One more thing that I would like to add is some stats on the length of exponents that we have found. (Like how many with 20 digits, how many with 21 digits etc.)

All and any suggestions are welcome. It doesn't matter how small.

Oh, one more thing that I should mention is that only the stats in "completed missions (plus my own results.txt files of my computers) have been included in the stats. I realise that there are some sets that are finished in the forum, but just while I am trying out some different things with the website, I won't be including the new sets for the next week or so. Once I have worked the kinks out of the website and added the stuff that is suggested (hint, hint) I will include all stats and move all the completed missions into the "completed missions" sub forum.

On [URL=][/URL] factors are not strictly in decreasing order.

[QUOTE=MrHappy]On [url][/url] factors are not strictly in decreasing order.[/QUOTE]

Well spotted. Should be fixed now. I mustn't have set a 2nd sort value.

A few of the largest factors are composites.

Ok, I know why my program didn't pick that one up. So at least that is a start.

[QUOTE=smh]A few of the largest factors are composites.[/QUOTE]

All the factors on my page haven't been checked to see if they are prime. This is probably something that should be considered though. It is a pity that prime95 doesn't "factor the factor" in the first place...

ET_ 2004-08-15 18:58

from the homepage: the column "P-1er" has a link to show "all factors found by..." . Would be possible to sort that page descending, by factor, instead of ascending, by exponent? Not that it is of any importance, just for a matter of "graphical order"... :whistle:

You did it fast and well, thank you!


Mersenne-ary 2004-08-15 20:56

Thank you Dave for your effort. I like it very much. :cool:

smh 2004-08-15 21:48

[QUOTE]It is a pity that prime95 doesn't "factor the factor" in the first place...[/QUOTE]

Or at least says it's prp or composite.

Same for the cofactor, especially for ecm on low numbers. Wouldn't be to hard to add in a next version, would it? :bow:
