 2015-09-08, 03:57 #12 danaj   "Dana Jacobsen" Feb 2011 Bangkok, TH 38A16 Posts Similar to your graph. To avoid extending it out very far I lump all the 300k+ into one bucket. I did this by putting together all the submission data, not looking at which records are still held, and not removing ones that were later overwritten by myself or others. 19 submissions in 2014, 12 in 2015. Since I'm running so many different search types, the shape of mine looks very different than yours. In 2014 I had a dip in the 50-80k range for some reason (speculation: this may be a reflection of 70k-120k just being easier to get records that year). In 2015 I've had more searches going on in that range, but now a big dip in the 36k-46k range. I suspect that's because most of my very long running searches have moved up to the 50k+ range, but I started a few new ones that have pushed up the small sizes.

 2015-09-08, 04:31 #13 danaj   "Dana Jacobsen" Feb 2011 Bangkok, TH 90610 Posts You said you were getting 125 gaps/week/core, which is about 18 gaps/day/core. My best two searches are at 19-21 gaps/day/core. They're right in that good spot of 80-110k now. I have one running in the 20k range getting 11 gaps/day/core which I think is fantastic given the ~20 minimum merit for a record. Another two are getting about 10-11 gaps/day/core running a bit before and a bit after that most-efficient spot. 15 searches are in the 2-4 gaps/day/core range, mostly stuck in the 30k to 60k range. 11 searches are in the 1-2 gaps/day/core range, also in that 30kish range. Here's a fun one. I have 4 active searches that have found nothing in the last 6 days. I'll move them to something more productive.

Plus encouragement of other open source devs/writers like Kim Walisch, Wojciech Izykowski, David Cleaver, Mario Roy, the Pari/GP team, CRG IV, TOeS, etc. The list could go on a long time.
If I have seen further than others, it is by standing upon the shoulders of giants

OK I admit it! I'm using variations on your Perl script Primegap1.pl

I thought I had informed Dr. Nicely of this in my first submission to him, but on checking back I had not, sorry. This has been corrected in my email to him today.

 2015-09-29, 20:09 #18 danaj   "Dana Jacobsen" Feb 2011 Bangkok, TH 2×3×151 Posts All but one of the ones going down are no longer doing submissions. JKA has a bazillion projects going on -- I keep finding his records or work in many areas of this hobby (the latest being prime clusters / constellations / k-tuples). Rosenthal did a huge submission all at once, and I presume he's still running more. There's a lot of overlap in his searches and ours. Spielauer is an interesting one, as it seems most of his current work is in the 30-70 digit range, but he had quite a few larger results that are getting hit by Gapcoin. I occasionally take one (looks like 22 total over the last 2 weeks). The current records in this range are fairly high so while each test is very fast, finding records is hard.

 2015-10-08, 00:16 #20 danaj   "Dana Jacobsen" Feb 2011 Bangkok, TH 90610 Posts New graph. Arguably too many people on it to follow. Gapcoin has two major lines. You can see Rosenthal's lines (k*M#/30 with each line being a particular M) as well as a few of my similar ones. While each update sees MJPCJKA drop a few more, there are still substantial clouds of their results. Attached Thumbnails

Massively beautiful.

Another good graph would show the changes say since the start of 2015 to show where work is happening.

Agreed, another good one would be with Dana's massive contribution removed - give us a chance to see where others are working more easily .

Here's one just showing my work, a lot of which is off to the right of Dana's graph.

Edited to add a graph of Rob's work.
