Hi Bhaskar, It is fine for multiple applicants to suggest similar projects. There are plenty of other things to do in terms of refactoring and optimising that will become possible as the initial refactoring becomes complete. For example we should add benchmarks to the benchmarks repo and profile and optimise each of the different solvers. We should also optimise the ordering of the solvers and the matching code. As part of the refactoring we should simplify each of the solvers as much as possible.
There are many things that can be done to improve the ODE module more generally such as adding solvers for classes of ODEs that are not yet recognised like the Legendre ODE. There is a solver for Bessel's equation but the GSOC ideas page links to an algorithm that can transform many different ODEs into Bessel's equation by substitution. There is a half-implemented method based on a published algorithm for transforming ODEs into hypergeometric ODEs. More generally lots of the ODE solvers could be changed to work through substitution. There should be a function for performing substitutions on ODEs (it is not trivial to do). In terms of refactoring the work that I have already described and that has begun is only really the beginning. Ultimately the ODE solving code should be structured as a rules engine with a set of rules that lead to other rules and so on in a similar way to manualintegrate. That would make is possible to get solutions "by steps".
