Ok, now I know a little bit what Sage is, at least it has its own syntax and can be integrated into Python. My problem is now that I need to implement this multivariate polynomial stuff in the NS-2 network simulator which is written in C++. The only thing that I could find is a discussion about the incorporation of LiDIA code into Sage, what appears to be a problem since its C++. I would be really happy to use Sage since it contains the polynomial stuff I need. If any exprienced Sage user has a suggestion how to use Sage in C++ I would be really thankful.
