Aliquot sequence worker for factordb
Hello,
maybe somebody is interested to use my Perl script to drive Aliquot Sequences in factordb. Is a helper tool which drives Aliquot Sequences in factordb. USAGE: ali.pl <sequence> <max composite length> <threads> It fetches the last index for the given <sequence> and checks if there is a composite left. If the composite has more than <max composite length> digits it continues with the next sequence. Otherwise it runs yafu for this composites and reports the given factors into the factordb. Afterwards it again fetches the last index for this sequence and continues. Yafu is started with parallel <threads>. Here is the source. yoyo Last fiddled with by yoyo on 20120112 at 14:02

No, it doesn't parse the forum threads. I'haven't implemented a forum bot.

It appears if you change the sequence type from 1 to within the range 211, one should be able to process a Home Prime Base 211 Aliquot Sequence.
Code:
my $contents = get("http://factorization.ath.cx/sequences.php?se=1&eff=2&aq=$seq&action=last&fr=0&to=100");

I haven't found a way to figure out which sequences are open.

Do you mean the aliquot sequences? You can use bchaffin's list or mine from here. It's a list of all the open sequences, along with the last line info. (I haven't updated it to remove the last two merges that have just been found....)
