How does the system identification toolbox does the estimation?

Hi,

I want to know the inside of the system identification toolbox. As I have attached a screenshot while estimating a model it says Initialization complete. Nonlinear least squares with automatically chosen line search method. then there are iterations going on. How does it determine how many iterations to do to terminate at some point? I want to know the method to have a clear idea on how it is working to explain this to my professor.

Thank you.
