Hi fellows,
I am using fmincon to do the optimization problem. But every time I run it it gives me different result. Is there anyone who know what the reason could be?
Cheers

  • Do you have a rand() in there that makes your function non-deterministic?
  • Is your function non-deterministic in some other way?
  • Are you using the same starting point, x0?
  • Are you modifying the options at all?
The more details you can provide us with the better.
