[QUOTE=Dubslow;304266]What is five.txt?[/quote]It is/was a file that Clifford posted on his page showing his local status (his main area of interest was the sequences with 5 digit leaders).

Sometimes he had work shown as being done that was not uploaded to the DB. (He did all of his work alone/locally and did not upload as frequently as we MFites do.) For example, his last file showed this:[code] 99240 602. 2^2 * 3 * 7 C102 sz 105[/code]I'm sure the aliquot workers extended 99240, but, as noted, there are some that were/are shown as being farther along than the work in the DB....

I'll attach the "current" five.txt to save you the trouble of searching for it.

Indeed, I changed my factordb-updating tactics on downdrivers from "teasers" (leave a downdirver hanging) to "mum's the word" after the April thing. 99240 had not one but half a dozen downdrivers with cliffhangers; I had not teased even a single one.

--Additionally, as kar_bon suggested, the script now tracks the FDB ID of the last line, and once a week I run a script to check for any duplicates, i.e. merges. Also like he mentioned, the major flaw is that if a merged pair is updated between when I get the first branch and get the second branch, then the merge won't be detected. (It will take a week for the ID list to be fully populated.) (If you look hard enough, the ID is available for each sequence.)

Well then they somehow didn't make it into schickel's last report.

I use the table data from my webpage, which in turn got its initial list of 9231 sequences from AllSeq.txt.

Since then, you've created two terminations, you had another merge with 3366, and the three merges above, two of which were apparently known but missed AllSeq.txt. (The version of AllSeq I started with was in the reservations thread, which has been recently cleaned...)

Batalov 2012-07-21 23:02

594228 and 493410 were not in the recent AllSeq.txt. They were only in the old one. Also, my count of open sequences is 9226.

EDIT: added the merge to the post [I]#2[/I] (due to its size at merge). Frank, you can move it to post #1 but let's just not have it there twice.

schickel 2012-07-22 04:57

I probably won't reply to each message individually, but here is a general reply to the above messages.

I believe I started out the AllSeq list by scraping kar_bon's list from his RieselPrime.de [URL="http://rieselprime.de/Others/AliquotIntro.htm"]page[/URL]. At the point I started pulling a (semi-)regular status on everything, I deleted our terminations and merges from the list as they occurred. I noticed that my count tracked Wolfgang's count to within +/- 1, but I figured that was OK because he wasn't always updating immediately.

I [I]thought[/I] I was keeping up to date with everything as we went, but I noticed that I ended up +2 from Wolfgang's count and could never figure out why.

I'll have to sit down and update the list from everything discovered here. If I find any problems, I'll offer a "double your money back" guarantee[SUP]*[/SUP] to anyone who was affected by the errors.

[sup]*[/sup][SIZE="1"]Double money back includes only the amount paid for the AllSeq.txt file. Internet access charges, SMS fees, text or data overages, electricity used while factoring already factored numbers, pain and suffering damages, time spent waiting for the FactorDB to reset your query/page/ID creation counters, and/or any incidental fees are not covered.

Hmmmm.....

The last time I pulled the 2^3 * 3 thread was June 8. At that time, 832314 showed this:[code]832314 2263. sz 113 2^2 * 3 * 5[/code]Someone moved it up over the hump and down a huge downdriver slope. Since a) no-one noticed the [STRIKE]large[/STRIKE] huge downdriver run, b) I don't see a reservation anywhere, and c) the remaining composite was probably <110 digits (maybe a little more), I would be inclined to chalk this up to bchaffin's workers. What do y'all think?

BTW, just to make it official: 889908:i4 = 832314:i3201 = 2694160.

As re the other two merges mentioned: looks like I had my files get out of sync a little. I broke the list into 3 parts to make it a little easier to pull everything. I had the split files in two places, so I may have let an old file slip through the last time I pulled.

That's the first time I noticed Batalov's comment.

Like I said above, I started with an [URL="http://www.mersenneforum.org/showthread.php?p=295896#post295896"]April 09[/URL] version of AllSeq.txt from your FTP server, and the changes I've recorded since then are in the post just above Batalov's note.

We should probably try and work out these discrepencies, perhaps perform a diff of some sort. To that end, I've attached a much simplified version of my list of 9225 OE sequences.

I've finished the screenscraping of FactorDB (I didn't ask Syd for special permissions so I could only get them in chunks of ~450 per hour over a couple days). Some lines are already dated on arrival. Anyway, here's the snapshot. 9226 seqs. It doesn't have any apparent merges; but of course it may have broken entries.

This sequence has merged to 53310 and is not a part of the currently tracked 9226 sequences. The merge doesn't seem to be recorded in the forum tables, though.

This isn't surprising because the merge (215778:i386 = 53310:i229 = 266554) is very early and the max height of 215778 was only 24 digits.
FactorEyes's [url=http://www.mersenneforum.org/showthread.php?p=235703]reservation[/url] is the first mention of sequence 215778 that I can find; it may have been a typo.

I looked in my old data and found this merge in long forgotten days. Sorry, but I cannot reconstruct it. A merge lower than C30 will find the basic programm I used to compute my record file.
There is 215788 marked with -53310, what means, that there must be a merge to this sequence...

[QUOTE="Clifford Stern"]My efforts to obtain a new terminating sequence have hit a multi-year dry spell.
However, I managed to get a new merger today:

574344:i2514 = 5748:i15 = 246584

I think this is a new high (124) for a sequence before merging. I begain working on
it August 9th when it was at 800. 2^2 * 3^2 sz 118.

schickel 2012-11-29 05:22

[QUOTE=Dubslow;319903]Is that the first [i]termination[/i] after having a large D6?[/QUOTE]Probably not. The only way to be sure would be to check all the previous terminations, but the ssumption could be made that most sequences get captured and escape drivers while they are under 100 digits. Also, excepting the full 2^9 driver, all the other drivers seem well represented.....

My congratulations - termination at p=37 is what I prefer...

I might be missing something, but doesn't Aliqueit only detect the new index falling below the original number as a merge?

The old db used to display these other merges, but the new one hasn't had this feature implemented, yet.

Batalov 2013-03-15 20:32

Yes, the onus is on the researcher. It is tricky, but it can be done.

For example, if one of my sequences goes reasonably deep and then climbs up to, say, c70s, it is a good idea to submit it right then. After submission, check what the database would show - and if it would show a c115 or larger, then you happily kill the running process and start checking to what sequence it merged. [SIZE=1](which in itself is a separate story, left as an exercise to the reader; one hint would be to use Bill's "status database")[/SIZE]

Indeed.

If Jatheski hadn't been looking, I'm reasonably confident that I would have detected it within a week -- I have a script that checks my page daily for merges. (I'll leave this merge in my page for now as a test of my confidence. :smile:)

PS: Have added already 2500 lines, but now there are much more lines in the DB.

PPS: 467658 merges with 247296 and so releasing it :whistle:[/QUOTE]Does your automation keep detailed logs, Tom? (So we can figure out a date...) (And maybe you should add an alert if something gets down below ~12 digits or so.....)

Officially: [B]467658:i10 = 247296:i3037 = 410529720[/B]!!!!!

So we had another sequence go up and come back down to merge with a higher sequence.....pretty cool. (So far Dubslow's spider has not picked up the extension of 247296....)

fivemack 2013-04-14 09:30

I haven't started 247296 yet: I just drop the numbers into a hopper and run make -j8 on an eight-core machine. I've removed it from the hopper and am leaving it to RobertS.
