Hi Abhinav,

Nobody has solved #401 so you are welcome to try, but Stephen Tu hasn't
been actively working on mlpack in a while, so the amount of support you
will be able to get is not huge.  If you'd like to work on that, I'd
suggest studying SDPs and then studying the mlpack optimizers.
Stephen's existing comments on the bug do provide a good place to start,
so once you have familiarized yourself with SDPs and mlpack's
implementation of them, you can take a look at lrsdp_function_impl.hpp
like he suggests and see how a linear constraint could be added along
with dense and sparse constraints:

https://github.com/mlpack/mlpack/blob/master/src/mlpack/core/optimizers/sdp/lrsdp_function_impl.hpp

I hope this is helpful.

Thanks,

Ryan
