Ebook: Practical methods for optimal control using nonlinear programming

Many books on optimal control are not practical, because to solve real problems we often need to apply numerical methods.
So that the subject of the book is extremely important.
However, the organization of this book is a complete mess. It mixes some pieces of optimization topics, written in a generic manner that are not sufficient to implement any algorithm. You need to know the topics from another book. Then the book isnt so practical as the author says.
