NaN——Status: Infeasible Optimal value (cvx-optval): - Inf

[ls1128uhbdnjnefk]

Hello, I also encountered that during the optimization process, the optimization objective changed to NaN,
Status: Infeasible
Optimal value (cvx-optval): - Inf
When I saw the explanation for “Debugging infeasible models” at the end, I understood its meaning that it may display a failure every time the final constraint is run, but he didn’t continue to say it later, only said: “Hence.”, we have reduced the model to a much smaller model which we now must analyze in greater detail to understand why it is infeasible.
I would like to ask, how did I solve it next
I carry the results of each iteration into the next iteration, and sometimes when NaN appears, I don’t feel like I think the order of magnitude is too small and treat it as 0.
My version is cvx 2.2, mosek9. x

Unsafeguarded SCA can be very unreliable.

The result obtained using the SeDuMi solver is inaccurate. The optimal solution is not as good as before the optimization.

Unsafeguarded (no line search or trust region)Successive Convex Approximation (SCA) or generally, alternating variables optimization are unreliable. It might not descend (for minimization problem), i.e., iterates could get worse. It might not converge to anything; and if it does converge, it might not be to a local optimum of the original problem, let alone a global optimum. The solution of successive iterations, and therefore subproblem inputs, can become wilder and wilder, until at some point …

Thank you very much for your reply. I will continue to revise my code
