Hi ,
Thank you for you reply.
According to my understanding from your reply, do you means that if we ignore the length of processing time, the nowadays optimization techiques should be able to solve all reasonable problem?

Many non-convex optimization problems are impossible to solve in
affordable time,space and power. In fact, if you can solve ALL
optimization problems then there is no need for any more researches.
