736950 went up to 102 digits for three iterations, but is now back at 101 for a couple. Should I consider it finished or let it run for awhile to see where it goes?

It's up to you, but if I were you I'd let it keep going. The guide you've got now is 2^2, which tends to make the sequence go down slowly.

Greebley · 2009-12-21, 03:23

I keep many of the hopeful ones in an attempt to find the terminating ones. 2^2 is also one of the best guides (it has been called the down guide). As mentioned though, it is your choice whether you want to explore further or let someone else do it.

I have started a collection of sequences without drivers that I run with the -q option to do only one iteration so I can switch between them - but only because I have a second computer to run them while still running at least one of these.

EdH · 2009-12-21, 03:57

Thanks,

Maybe I'll keep it awhile. I am running two machines (one each) against the two numbers I have reserved, but the other one is getting really slow. Actually both of these have been hitting some numbers that are taking a few hours to sieve. They seem to take off for a few lines when they finally make it through. I have a third (linux) machine I was trying to run gmp-ecm on, to see if I could find a factor that way, but I'm not sure I know what I'm doing there, yet.

Oh, well, a little more playing, I guess. This one (736950) did have a down run in the late 700's-early 800's and made it down to 79 digits for a while, before turning upward again.

Take Care,
Ed

That should have read "79 digits for a while." I guess you can't edit after you've logged out and back in...

The limit on post editing is 60 minutes (unless you're a mod of course). But as I'm a mod, I'll correct the error.

Thanks, I'll try to be more error-free..

I've run 736194 up to 100 digits, 2 * 3^2 * 5 * 701 * 823

So I now release it.

I've moved 736950 over to a machine I have running continuously now. Let's see where it goes.

I'd also like to reserve 738936.

Take Care,
Ed
