Comment (by novoselt):
I would prefer a suffix, rather than prefix, but I guess for courses you
tell the name to students anyway and with a cross-link it is easy to
discover.
Regarding parameters being the same or not - please don't do it here to
avoid breaking anything, it will require careful changes in documentation.
And in general the behaviour is different enough that sameness of input
does not matter much, so I'd prefer to not touch it at all. What would be
nice to have are conversion functions between regular and educational
versions, but when I was working on them I was hitting corner cases bugs
in MILP and never finished. Will add to my todo list, especially if I get
to teach this course in May/June.
Regarding types: the education version actually works best with exact
rings like QQ. For floating point there is nothing to deal with
degeneracy, which is actually nice for education:
