<div dir="ltr"><div><div>Hi CSDP users/developers,<br></div>I am trying to solve a SDP problem inside a code in C. The structure of the SDP formulation I have is such that I can always guarantee a feasible solution no matter how big sample size is. CSDP successfully solves the problem with small sample sizes; but when the sample size grows it keeps giving up saying lack of progress or stuck on the edge of primal feasibility. <br>
<br>I generated such a moderately large problem in SDPA sparse format (attached here, it has 661 constraints, 2 blocks in the X,Z matrices with sizes 12 -671) and fed it into MATLAB solvers such as SDPT3 and Sedumi and both of them gave the correct solution. Using the same input file I just couldn't get even a feasible solution from CSDP. <br>
<br></div><div>I've also played with the parameters to no avail... <br></div><div>Do you have any suggestions? Is there a setting to make it behave the same as those MATLAB solvers?<br></div><div>Thank you very much!<br>
