Dear All,
I am using LSQNONLIN to estimate my parameter in a complex chemical system. I am going to use "trust region reflective" algorithm, but I need to know how exactly it works. I mean, I am looking for the mathematical background behind it. Meanwhile, I studied the link below, but unfortunately, I didn't understand it.

I would be thankful if you could help me.
Best,

If it's an introduction to trust region methods that you're looking for, this book is pretty good
