Search all bases with <= 10,000 k's remaining (at n=2500) to n>=10K; 8/11 bases completed. 2. Search all bases with <= 3000 k's remaining (at n=10K) to n>=25K; 6/21 bases completed. 3. Search all bases with <= 20 k's remaining to n>=300K; 9/13 bases completed. 4. Search all bases < 700 with 2 k's remaining to n>=500K; 8/17 bases completed. 5. Search all bases < 700 with 1 k remaining to n>=600K; 7/13 bases completed. 6. Search all bases < 215 with 1 k remaining to n>=1M; 1/7 bases completed. 7. Complete Riesel base 2 2nd conjecture to n>=7M; 28 k's for n=5M-7M; 1M/2M n-range completed. 8. Complete all Riesel base 2/4 odd/even k's and n's to n>=10M base 2: 8 k's for n=9M-10M base 2 including 2 k's for R2 even-k, 1 k for R2 even-n, 4 k's for R2 odd-n, & 1 k for R4 9. Complete R3 for k<20G to n>=200K: 17,542 k's for k=10G-20G n=100K-200K 10. Complete S3 for k<40G to n>=100K: 125,383 k's for k=1G-40G n=50K-100K 11. Complete R10 & S10 to n>=3M: 2 k's for n=2M-3M; 1/2 bases completed. 12. Complete R66 for k<30M to n>=50K: 18,833 k's for k<30M n=25K-50K 13. Complete S66 to n>=50K: 10,113 k's for k>5M n=25K-50K; 5M/16.314M k-range completed. 14. Complete S79 to n>=100K: 6971 k's for k>3K n=50K-100K I have added more goals but have lowered the difficulty on many of them this year. More of the goals this year are oriented toward individuals instead of SRBase. I have also removed primes and proof goals. Thanks to everyone who made suggestions about the goals! They saved me quite a bit of time in thinking through things. I'm confident that we can accomplish most or all of these goals. All help is appreciated!

Can you add all missing goals to the recommended list?

The thinking behind the recommended list is categories of multiple bases that all need a similar type of search done. Goals 7 thru 14 fit more in the mode of unique-type searches on single bases that need to be done so would not fit easily on that list.

In a synopsis:

Goals 1 thru 6 are already on the recommended list.

Goals 9 thru 14 with the exception of goal 11 have 1000's of k's that will need to be done so a listing is not possible. If needed, I can provide lists of k's for sieving/searching.

Goal 11 for base 10 is a straightforward search of 2 k's with sieve files already finished and posted on the reservation pages. It could be one that SRBase works on this year. The size of 2 to 3 million digits fits well.

That leaves goals 7 and 8, which I will send you sieve files for later on. Goal 8 I already have a sieve file for it. I haven't sent it to you yet because I thought that goal 7 should be done first. It is a somewhat bigger effort and likely will yield several large primes. Goal 7 is being sieved by Yoyo at the moment and will be done in the next 2-3 days. It is my plan to forward that to you at that point.

SRBase shouldn't worry much about those. It will mostly be individuals here in this forum working on them. Mark proposed a number of them and I know he will work on some of them. I'll help coordinate many of them and maybe do some testing and sieving myself.

See the bottom of the 1st post here where I state that more of the goals are oriented towards individuals this year.

For this range of goals, I'd only suggest that SRBase work on goal 11 for base 10. Also maybe possibly goal 14 later this year. It would be similar to your current S51 effort.

ok, I will make a plan, a challenge or 2 this year can help us for sure.

 2023-01-19, 22:26 #8 KEP Quasi Admin Thing     May 2005 7×11×13 Posts In regards to goal 9: "9. Complete R3 for k<20e9 to n>=200K; 17,542 k's for k=10G-20G for n=100K-200K" I must point that I'm currently testing k=10G-11G for n>100K to n=250K for 1668 k's. Tomorrow they are done sieving to p=445G and I'll start LLR testing them. I had several issues using srsieve2, so I ended up going back to srsieve, since it was multiples faster - the same goes by the way with sr1sieve being faster for a single k sieve. I have not had time to investigate optimal settings for making srsieve2 faster, so it might be that I'm currently sieving slower than needed, but for the use of srsieve, p=445G was optimal for the menioned range.

srsieve2cl is the way to go if you have a GPU otherwise stick with sr1sieve/sr2sieve.

KEP, if you are planning to LLR something, can you please reserve it before you begin working on it? I'll go ahead and reserve it for you. Since this is a goal, will you be able to complete LLR on it this year?
