Hell !!
I have updated OO TSP page with link to the OpenOpt TSP class file:
Thank you ! It looks like you use the MTZ formulation, with some additional
simplifications when there are vertices of in/out degree 1 in the graph :-)
The formulation we have in Sage should be very

Honestly I don't think it's very constructive to tell users that they
should install a different operating system in order to use Sage, and

I totally agree
Hello,
I would like to factorize an expression with sage that contains constant
variables (i.e. parameters), but I cannot figure out how to do that.
Here is an example : x, y are variables and A is a parameter
*
var('A x y')
f = A*x + x + A^2*exp(y) + y
print (f.factor())

Thank you for your answer and sorry for the typo mistake.
Your solution works well with the example given but doesn't work as I
would like with exponents (x^2, ...).
Yeah it's not ideal. I needed to do this with symbolic derivatives, and
the method I posted
First of all, thanks for help.
You got exactly the point.
I saw the example you post. But is there a possibility, that i calculate
mandel within the plotfunction?

Hi,
How can I calculate the dual of an ideal using sage?
Thanks.
