Yeah. You're right. I also spent a half year to learn the documentation, technical points, and installation. I think updated documentation is necessary.

Hi all, Does anyone have experience on running the C++ SDPA code on a Window operating system? I transform from the Ubuntu system to a Window system. However, I encountered more than 100 errors when I was running the original code. Thank you. Regards, Ricky

I found the SDPA-C solver usually fails to get the optimal solution due to some numerical issues while other solves like SeDumi can solve it efficiently. As the attached two data file. How could I fix it? SDPA-C performs Cholesky factorization to solve the Schur complement system, and this step is not easy to be parallelized. So, I am wondering is it possible to lever some iterative methods to replace Cholesky factorization to develop a parallel one. SDPA-C do not perform the Mehrotra predictor-corrector...

Dear all, I am writing regarding some trouble in prapreing the data file for the SDPA-C solver. Since SDPA-C embedded the sparse clique factorization into the PDIP method, my trobule is whether I need to obtain the Chordal graph and maximal cliques of the problem before putting the data file problem into the solver. If I do this, how the SDPA-C figure out this since the data file has on infromation on the clique facotirzation. If not, does the solver do this inside? Another question is the sparse-clique...

Hi all, I just install the SDPA-C solver on ubuntu. However, I encountered a mistake when I execute the 'make all' command. Here is the screen output. Could you tell me how can I figure out this issue? Thank yo so much.

Hi all, I use the SDPA and Sedumi to solver a large sparse SDP. I found the Sedumi can solve the problem while SDPA told me that 'the step length is too small'. I am wondering is it possible for me to make SDPA to solve the problem by changing this condition? Best, Rui

Hi all, I am using the SDPA-C to solve a SDP problem on Liunx, however, I failed to install the SDPA-C, due to the targeted address: http://www.cise.ufl.edu/research/sparse/SuiteSparse/SuiteSparse-4.0.2.tar.gz is wrong. I am wondering how can I change this address. Thank you so much. Rui
