Aliquot sequence worker for factordb
 
Hello,

maybe somebody is interested to use my Perl script to drive [URL="http://factordb.com/sequences.php"]Aliquot Sequences[/URL] 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>.

Does this script parse the aliquot reservation and aliquot subproject threads (first posting each) to check whether the sequence it attempts to work on is reserved?

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 2-11, one should be able to process a Home Prime Base 2-11 Aliquot Sequence.

[CODE]my $contents = get("http://factorization.ath.cx/sequences.php?[COLOR="Red"]se=1[/COLOR]&eff=2&aq=$seq&action=last&fr=0&to=100");[/CODE]

It also appears each sequence number is processed consecutively instead of just the open-ended ones, which may be of more interest.

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

yoyo[/QUOTE]Do you mean the aliquot sequences? You can use bchaffin's list or mine from [URL="ftp://ftp.frontiernet.net/pub/users/aliquot/AllSeq.zip"]here[/URL]. 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....)

I did on my end ( since you let me look at the file, you can double check my edits if you want):
