I tried sage.misc.package.install_all_optional_packages() with machine
having too less free disk space. It seems that error handling does not
work: After freeing some space I had to manually remove .spkg-files to
get them installed.
This was with sage 5.0.1, but I haven't seen any discussion a

If you know the variables and that your coefficients will be integers, why
don't you key the dictionary on the polynomials coerced into the
appropriate polynomial ring, e.g. Z['x,y,z,w']? Then you can use the
dictionary to look up the original form of your equation.

Hello,
I am doing computations over the symbolic ring SR in order to (mostly)
preserve the structure of my expressions (e.g., (x+y)*(z+w) should
stay factored). Keeping the structure is important for later code
generation purposes.
I also frequently want to know whether two expressions are the s

Maybe this is not as hard as I thought, and wrote half an hour ago.

That is what I thought might be a problem. I have no idea if its even

Sounds very much like a non-linear fit will be able to figure out the 8
unknown parameters. You need a formula ("model") for impedance(frequency)
depending on the parameters. Having complex values is a bit of an extra
complication since fitting in Sage only works for real numbers. For
starters,
