That looks great, Sam, very interesting. Do I understand correctly
that the notebook is the sole representation of the algorithm? I
wonder if it makes sense to export the Mathematica code for
IntegrateRational from the notebook and post that too.

About translation to Maxima, depending on what Mathematica features
are used, it might be possible to run the function without translation
via Mixima, a Mathematica compatibility layer for Maxima, created by
John Lapeyre and making use of Fateman's Mockmma; see the fork which I
created: https://github.com/maxima-project-on-github/mixima

However, if the Mathematica functions go beyond what Mixima can
handle, it would be necessary to translate it by hand, filling in the
gaps as necessary.

All the best,

Robert
