Hi,
after a discussion
here: https://groups.google.com/d/topic/cvxopt/xQ-lR9ESijg/discussion
it turns out that there is enough CHOLMOD interface already in Sage, it's
just not documented properly.
Should I volunteer to get sparse Cholesky implemented for non-exact sparse
Sage matrices, via thi
Ahahaaha. Well, I wrote what I thought would be a "good if hard to read
implementation", and it turns out to be... slower O_O
I still do not really understand why, except that copying the graph takes
time, too. For some reason.
The code is slower in interesting case, and faster in stupid cases :

Hello,
I try to execute one of the examples for computing the variety of a system of
Boolean polynomials from the Sage reference manual:
http://www.sagemath.org/doc/reference/sage/rings/polynomial/pbori.html
and I get the error:

Hi everybody,
I'm trying to construct an algebra from a monoid. For exemple :
sage: M = FreeMonoid(3,['a','b','c'])
sage: M
Free monoid on 3 generators (a, b, c)
sage: M.algebra(QQ)
Free module generated by Free monoid on 3 generators (a, b, c) over
Rational Field
The problem is that I obtain a

If you want to play with digraphs attached is program for generating
digraph diregular cages of any girth and degree.

Well, for those things we may be happy to have a good C implementation. I
will try to do that quickly. How long is it, if I may ask, for such graphs
? Could you also give
