I need to understend how black box optimizer work. I need a real life example of how it hlps. So what I need: What was the task, what were parameters, what was the function to minimize and how it all worked toogether. I need deteiled info on this topic, please - wiki does not give lot of help...

    ...I was talking about the optimization algorithm. The NURBS is a different matter, and I've seen your question both in here and MO. I would merely say that if your control points are noisy, then NURBS might not be the appropriate approach.2010-12-14

Chapter 10 of Numerical Recipes has a good description of how the golden section search works in 1D, as well as description of multidimensional cases. You could see figure 10.1.1 in the obsolete C version (available free online)

Your question is quite broad but Tim Kelley's recent book may illuminate you as far as applications are concerned and one type of algorithm (implicit filtering): http://bookstore.siam.org/SE23.

A chapter of Tim Kelley's previous book also talks about implicit filtering and direct search: http://bookstore.siam.org/FR18 (see also http://www.siam.org/books/kelley/fr18).

A number of algorithms are detailed in the book by Conn, Scheinberg and Vicente, "Introduction to Derivative-Free Optimization" but this book doesn't have many applications: http://bookstore.siam.org/mp08. From the algorithmic and theoretical point of view, this is a strong book.

This is much more representative of recent research and state of the art than Numerical Recipes.
