High-precision SDPA solvers

[Dan Molzahn]

Hello,

I would first like to thank you for the excellent work you have done with YALMIP. It has been very helpful for my research in applications of conic programming. I am specifically investigating a sparse semidefinite program with applications to electric power systems engineering.

I would like to experiment with some of the high-precision solvers available in the SDPA family. Specifically, SDPA has the variants SDPA-GMP, which uses the GNU Multiple Precision Arithmetic Library (GMP), SDPA-DD, which uses double-double precision from the QD package, and SDPA-QD, which uses quad-double precision from the QD package. Is there any way call any of these variants from inside MATLAB using YALMIP? If not, do you have any recommendations on how to use these solvers in conjunction with an optimization problem formulated using YALMIP?

Thank you for your help.

They haven't released any MATLAB versions of those, so they are not reachable from YALMIP

[Dan Molzahn]

That's disappointing but understandable. Is there any way to export the problem to a form that I can manually solve with SDPA-GMP and then import the results back into MATLAB, or am I just out of luck for now?

Hi Molzahn,

This is Rui, have you solved the problem?

Cheers,

Rui
