Welcome to "Riesel Prime Search"

Kosmaj · 2005-10-31, 14:31

The new project was established less than 30 minutes ago and we are now ready to go! We already have two pending primes.

I'm sure more will come soon!

When you submit your primes please be sure to create a new prover's code and to include "RPS", the user-ID of the project, in the field next to the sieving program you used.

The first team effort has already started.

Finally, thanks to everybody who decided to join us and who helped us decide the name of the project quickly!

The project descriptive data (to be included in the Top-5000) page:

Quote:

The project is searching for Riesel primes k*2^n-1, k>1.
We have three subprojects as follows.
(1) k's that can produce many primes in the given range of exponent n,
(2) low-weight k's that produce a very small number of primes
[opposite to (1) above],
(3) small k < 300 (with exception of those k's already reserved by
other projects).

If you have any comments on this please let me know.

Citrix

Also I vote for rieselsearch as the name.

So will there be a new sub-forum?

There will be soon a new forum in the "Other Projects" section.

How is an outsider supposed to know which k are '15k', and which k are 'RPS'?

My back-filling of small primes for dense k's (be they 15*k for some k or not, but of course all the dense ones are) is done purely for the completeness of the record, and it would be nice to know how this split of ownership/responsibility will take place? Potentially, the tables at 15k.org look like the best record, but if they're not updated by dint of the k values being now RPS owned, then confusion will ensue -- at least for me. How is maintainance of those tables now going to be handled -- to whom should I report factors?

You should fix this typo before submitting the text ;)

Phil, we are now in the transition phase, please be patient for a while.

Omboo, thanks, it's fixed now.

Should new prover codes include 'NewPGen'?

Citrix · 2005-10-31, 18:00

If you guys have decided on using this sub forum please rename it to rps than 15k search.

There will be a new RPS sub-forum soon (off of "Other Projects")

What should old 15k searchers do with their current reservations? I'm testing a low-weight k=177941 n=1 to 1M, now n=710722. What project does this k belong to? What k's belong to the other (with forum on yahoo) project?

Kosmaj · 2005-10-31, 21:21

1) All low-weight and all k<300 stay with RPS.

2) If you already have a reserved 15k multiplier and find a prime it depends on you do you wish to report it using an RPS or 15k prover's code. In any case it "belongs" to you until you stop working on it.

3) Team work on k=2995125705, k=210885, and k=355424355 all stay with RPS but note that the last one has no new ranges to reserve.

4) If you want to reserve a new 15k multiplier from the "Robinson weight" page there is currently no sharing system with 15k in place. If you just want one or two of them in a coming week or so you can reserve them I think, then (2) above applies. Something general will be worked out soon.
