Hello there,

I'm starting to learn about MATLAB optimization methods.

I'm trying the Optimization Toolbox to minimize a predefined fuction using 'fmincon'.

I understand that the solver will minimize my function value as much as possible, taking into consideration my constrains.

But, is there any way to set up a minimum value to the 'objective function value'?

As you can see on the attached file, I'm trying to stop the iterations at value 0.01.

Thanks in advance.

If you are using sqp or sqp legacy or active set, then you can specify an ObjectiveLimit option.

And what about other optimization methods? Is there a way to specify it for e.g. pattern search or any other global optimization method? Thank you in advance for your answer!
