hi everyone,iam new in cvx,and i have some problems when i use cvx.

[xiaobuding111]

I am using the SCA method to convexify the problem, but I am unable to converge to a definite value in the mosek solver in cvx. NaN occurs when there are too many iterations, I don’t know how to solve my problem, need help, thanks!

As for your question, my post from yesterday is pertinent:

Status : Inaccurate/Solved

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 …
