Statistics and scoring
This thread contains information about the scoring system at NPLB.
On www.rieselprime.de > menu "NPLB" You can find many project information and links to the current scoring tables. Also available is the status of the Team Drives with current reservations and completions and found primes too. Scoring for a prime with exponent n: Notes:
where av is the average of the range ⇒ . Notes:
The score is gained from the k/npairs done. Open questions: none Karsten Last fiddled with by kar_bon on 20100225 at 01:42 Reason: Menu selection changed

I'm not fond of TOO many scoring statistics because they become unwieldly to maintain. I like the primes scoring approach but I'm not sure about having additional scoring for ranges searched or other things.
Karsten, you're call there. I think you said you would keep the scoring so I'll leave it up to you as to what you think you can maintain. One thing I suppose we could do...add a little extra scoring for the lower ranges in drive #2 since there is somewhat less motivation to search them. Perhaps add ~70k the nvalue for them for scoring purposes. This would make the 260k333.2k range score like ~330k403.2k. So people would actually get MORE score per CPU minute/hour/day since they take less time to LLR. Another option is to score the drives separately but I feel we'd be getting into a little too much scoring and I don't think the incentive would be as great to score high on 'small drive' #2 compared to scoring high on an overall score for both drives.

I belong to a distributed computing team called FreeDC (www.freedc.org). Like Riesel Base 5 PRP I would like to see NPLB with team support.

I want him to add a column with the team name for each member on NPLB and process an overall stats page for teams..lol

I was just looking at the scoring page a moment ago, when I noticed that I was ranked right below CedricVonck for completed rangesI had a slightly lower score (even though we each have done one range total so far), despite the fact that he had less candidates in his range than I did. And even though mine was a 2nd drive range (whereas his was a 1st drive range, and thus higher n), wouldn't it still be scored higher, because of the added bonus for searching nontop5000 ranges?

your range was 260800 to 261000 (with bonus of +70000 > 330800 to 331000). Cedrick got range 333400 to 333600. calculation: anon: 330900*330900*ln(330900)*200/10^14 Cedrick: 333500*333500*ln(333500)*200/10^14 so because your range is slightly lower (although bonus included) than the other and therefore the scoring is correct so far. a range from team dirve #2 of 263400 to 263600 is the same as that from Cedrick! the number of candidates is not relevant here. karsten

I can't help but note that after the Twin Prime Search primes fall off the list a few months from now, a person could find themselves in the position of actively crunching the project, maybe even increasing in rank, and yet getting lower and lower scores.
Maybe we should archive a list, starting now, of the digit length of the prime at 5,000th place every first of the month. If someone gets discouraged, they have the option of making new comparisons based on a nonmoving target, the value of the 5,000th placed prime in a given month. Is it possible to simply calculate a simple normalization value? (Not sure if normalization is the right term. )

i'm calculating all scoring in Ex*el and the divisor of the formula is stored as constant in one cell i use. so i only have to edit '333333' into '350000' (or what ever) and the new calculations will be shown immedeatly!
so, no problem. or do you meant a new formula at all?
