Working of PSO with hybrid function

I am using PSO with hybird function (in my case I am using fmincon) for my optimisation problem, and I am stuck with confuison about the working methodology. In documentation, it is written 'A hybrid function is another minimization function that runs after the particle swarm algorithm terminates', does it mean hybrid funtion runs after PSO at each iteration or it means hybrid function works when PSO wont be able to minimize the objective function further.

An explanation will be appreciated.

Thanks.

It means the hybrid function runs after particleswarm stops. Ends. Is done. That's what terminates means. In fact, it is equivalent to run particleswarm without a hybrid function, then run fmincon starting from the particleswarm solution.

Usually, you use a hybrid function to obtain a more accurate local solution. I hope that is what you are trying to achieve.

Thank you for the clarification.
