Yes, this is the purpose of the C class. Sometimes it is impossible to import something directly because of circular imports, so we have the C class to get around it. > > As I am fairly new to Python and Sympy I do not know if this is a > quirk or what. > > Also regarding Gsoc I was interested in implementing a subset of > Combinatorica, say, the most important functions in the subsets, > permutations, group theory and graph visualization and drawing. > I can implement a sizable amount of these algorithms as I have > exposure to functional programming and I think I can use the > functional constructs of Python to do the job. > Alternatively, I found the Karr summation problem to be interesting as > well but I will need to do a lot of research before I can commit any > code in. I would recommend doing the combinatorica project. The Karr algorithm is very difficult. Also, you need to finish up the review of your integral equations module so that it gets pushed in. Otherwise, you will not be eligible.
