I'm not sure if I understand what you mean by "tests". > >> It definitely shouldn't go in physics, since calculus of variations is >> useful to more than just physics! > > I agree.

It actually makes sense to me to have all the solvers together (solvers, ode, pde, recur, etc.). integrals does indeed deserve its own module, because it will get very large as more and more of the integration algorithm is implemented. Anyway, where do you think it should go given the way things are? I don't have any ideas.
