Dear Team,
40 minutes ago, i was sending a mail for this thread, using my usual
mail account rather than this web interface, since i wanted to attach
the log files. As subject, i took "Performance of the Singular
interface", hence, the subject of the thread. But apparently it did
not arrive. www:

Yes, if it is a complete log then this should be enough. I.e. if I can replay
that log to Singular and get the same behavior then this should be
sufficie

Dear sage-support team,
this is another questions on how to use the Singular interface in an
efficient way; so i hope it is ok to use the same thread.
Let G be some Gröbner basis, obtained with Singular (via the
interface). I'd like to have a list comprising the exponent vector (as
a python list

I trie
Simon,
could you send me/us an example to reproduce this? I don't really buy
mabshoff's remark about quadratic runtime of the pexpect interface here
because the input and output are very very little. Btw. mabshoff why is it
quadratic anyway?
Also, getting this functionality into libSINGULAR i

No, it is simply

where sz is ncols(I)+1, and p is a polynomial.
Of course, that line of c
Is it recomputing a Grobner basis for the new ideal? That could be slow.
