New description:
Users who want to solve a Semidefinite Program, using Sage, have to
express the problem in a very restrictive standard form which is required
by the solvers, rather than in a natural way that follows mathematical
conventions. By creating an interface, similar to the MILP interface, the
user should have a much easier time solving an SDP. We aim to create an
SDP interface and a backend for CVXOPT, capable of solving simple SDP
problems.
The original code to the interface can be found here
https://github.com/ingolfured/sageproject/blob/master/src/sage/numerical/sdp.pyx
and the backend for cvxopt can be found here
https://github.com/ingolfured/sageproject/blob/master/src/sage/numerical/backends/cvxopt_sdp_backend.pyx
Added (slightly patched) to trac.

Comment:
