Title: A superb book to learn from.
Review: This is a perfect book to study in detail. Prof. Luenberger brings a set of topics in analysis that is related to optimization into one coherent exposition. I took a graduate course using this book with a great professor. I must say that the experience is an eye opener for me. The topics are very interesting and well motivated, the proofs are elegant. It keeps on delighting chapter after chapter. I can't overstate the enthusiasm the book generated in me to study mathematics further. The book is absolutely the best.
