That project ideas page isn't very complete. A much better ideas page is the GSoC ideas page https://github.com/sympy/sympy/wiki/GSoC-2018-Ideas, or even the issue tracker.

I think they do, but I'm not entirely familiar with them so I can't say for sure. Aaron Meurer -- You received this message because you are subscribed to the Google Groups "sympy" group.
