Hello,
I have committed some more patches for ECL on the Maxima CVS
branch patches-for-ecl-branch. With the stuff currently at the end of

Hello folks,
it is probably too late for a formal Bug Day this Saturday, but I
would suggest the usual Saturday review and merge session in #sage-
devel. Hopefully 3.0.2 will be out by then, so we can be aggressive
about merging code.
Thoughts?
Cheers,
Michael

Andrey,
The bundle probably would not be of much use to you, since the
function takes as input a Sage multivariate polynomial ring element
and outputs a Sage elliptic curve over some field, when all you want
is symbolic expression in Weierstrass normal form.

It is possible to create a polynomial over the symbolic ring, i.e. SR

Andrey,
Check out the hg bundle attached to this ticket:

Bobby Moretti was implementing code for doing this transformation, but
never finished due to a subtle bug in the transformation maps (he gets the
right cubic but not the right maps). It's
Maybe, but the coefficients are symbolic non-polynomial (and non-
rational) expressions. Can it be done anyway? I also had problems with
subtracting 1 from an expression, which I got by substituting rational
functions into a polynomial, so I switched to symbolic representation.

There is definitely going to be some form of pattern matching, as it
is pretty much required by simplification. The exact syntax isn't
decided yet.
1) Everything has been converted to Cython and all of the internals
are pure Cython with no or very few python function calls. The code
is essential
I tried to convert
2*x*y^2 + 2*a5*t*x*y - x^2 + (2*a4 - 8*t^3)*x - 1,
where a4, a5, and t are some complex parameters (which I would like to
keep as undetermined parameters), to Weierstrass normal form using
Nagell's algorithm and was not quite successful since some steps near
the end do not finis
It almost sounds to me like you'd rather be working in a multivariate
polynomial ring (which will be much, much faster).

Actually, yesterday was the first time I really tried to use Sage for
symbolic computations and it was quite frustrating for me.
1) It would be really nice if it was faster.
2) It seems to me that
((x+y)*y).coeff(y^2)
and
((x+y)*y).expand().coeff(y^2)
should return the same coefficient 1 (while

I should add that many thanks go to Chris Brown for not only much
development work on these packages, but also for all the work to get
these relicensed. Thanks, Chris!

The asymptotics really only kick in when we are using Strassen. The
starting point is thus not 0, but the crossover point between M4RM and
Strassen. So I don't think you can read too much into the asymptotic
statement. But once the asymptotics do kick in, we aren't too far off.

You can talk to a Sage server over HTTP and can find examples of how
