Hi Kaiqiang,

I took a quick look at the proposal; it seems me to like step 2 might be
a little redundant.  You have written:

  "2. Check the correctness of implementation of LRSDP.  Design several
      special simple/hard problem, such as the Lovasz theta SDP, the
      maximum cut SDP relaxation and etc."

but I thought I should point out that we already have these in mlpack;
see src/mlpack/tests/lrsdp_test.cpp.  So maybe this will help you save
some time since you will not need to implement that yourself.

Thanks,

Ryan
