README for non-PLEXOS users

I see #3 rearranging some files for non-PLEXOS users. But, I am still struggling to figure out how to use the RTS data for Argonne's work. Is there any plan...

Update SDP Formulations to use SkewSymMatrixSpace

4

I wonder if this variable `WI` should have been created as `Symmetric`. https://github.com/lanl-ansi/PowerModels.jl/blob/12d560e951446e23ac173cda532ac11157f9ca8b/src/form/wrm.jl#L52-L53

CPLEX barrier occasionally returns the code related numerical issues when solving the master problem of dual decomposition.

Need to check whether generic structured QCPs are supported in #243

Testing on branch `dev/qcqp` ``` cpx_drdd_sslp_BB cpx_drdd_sslp_BC cpx_drdd_sslp_CC ``` The test instances above terminated with unbounded subproblem. The test still passed.

Upper bounding in the dual decomposition of MIQCP

1

This is an issue for our development branch: `dev/qcqp`. Computing upper bounds in the DD of MIQCP may not have been implemented.

The work started before, but I believe it is not complete. We need to decide whether we want to add this support to `dev/qcqp`.

SCIP warning message from testing on branch `dev/qcqp`

Branch `dev/qcqp` ``` scip_qc_de_farmer scip_qc_dd_farmer scip_qc_de_farmer2 scip_qc_dd_farmer2 scip_qc_de_farmer3 scip_qc_dd_farmer3 scip_qc_de_farmer4 scip_qc_dd_farmer4 ``` The test instances above display the warning message such as ``` WARNING: Original variable not released when freeing...

Support `dw` method for MIQCP

1

In the current implementation, the `dw` method ignores the quadratic constraints without any message. We should do one of the following: 1. display a warning message 2. implement the support...
