i hope quartic as well
i dont see that we will be using sextic polys in aliquot searching for many years

Indeed.

I thought of a feature I would like to see.

The ability to have aliqueit stop if it reaches a certain number of digits - so if 120 digits are reached it stops.

A more advanced form would be to stop if it reaches a certain number of digits AND is in control of a upward driver. (list of drivers in the ini file??) So '120D' would mean that it could go over 120 digits, but only stop when it also had a driver forcing it upward.

The final form would be a way to specify a 'batch file' with more than one number to process. Something with lines of the form
<number> <limit>

so for example a file with:

233058 120
233100 120D

would mean go to 120 digits (or termination) with sequence 233058 and then run 233100 until it has both 120 digits and a driver driving it upward.

---

This would make it easier to take several numbers up to say 100 or 120 digits. The driver part keeps you from quitting when there is greater hope you will go down again.

Currently single sequences are mostly being done, but someone might want to take all the 400K numbers to 100 digits for example. You could do this more easily with this functionality.

BTW, I really like the program.

Do I see this correctly - is wget a linux program? If yes, is there a windows binary available (or can please someone post a windows binary)?

perhaps this helps: http://unxutils.sourceforge.net/

It is in this .zip from mklasson's site.

Yeah, this could be nice. I've added it to my ever-growing todo list.

Glad to hear it.

Latest wget version can be found at http://wget.addictivecode.org/Freque...t=Faq#download.

I just benchmarked GNFS with a quartic against yafu on a c92: GNFS takes a total time of 01:21:20 hours, yafu takes 01:50:00 hours, so GNFS is quite a bit faster on this input size.

So for all who are already using msieve 1.42 beta, I suggest lowering the GNFS_cutoff in the aliqueit.ini file to 90 digits (BTW: If I understood correctly, 90 digits is the minimum input size where msieve will do GNFS poly selection.).


Edit: Does wget need to be in the aliqueit directory if I want to automatically upload new lines of my aliquot sequences to the database?

Awesome! That's with an optimised 64-bit gnfs-lasieve* under linux though, right? I wonder what the optimal cutoff is for a sluggish windows system...

I am pretty sure Andi is using a sluggish Windows system.

Either there or somewhere included in your PATH env. var. Am I the only one still actively using the PATH variable? A nice directory such as c:\utils with all sorts of useful tools in it is very handy imho.
