The primary goal of this book is to provide a self-contained, comprehensive study of the main ﬁrst-order methods that are frequently used in solving large-scale problems. First-order methods exploit information on values and gradients/subgradients (but not Hessians) of the functions composing the model under consideration. With the increase in the number of applications that can be modeled as large or even huge-scale optimization problems, there has been a revived interest in using simple methods that require low iteration cost as well as low memory storage.

The author has gathered, reorganized, and synthesized (in a unified manner) many results that are currently scattered throughout the literature, many of which cannot be typically found in optimization books.

First-Order Methods in Optimization

• offers comprehensive study of first-order methods with the theoretical foundations;
• provides plentiful examples and illustrations;
• emphasizes rates of convergence and complexity analysis of the main first-order methods used to solve large-scale problems; and
• covers both variables and functional decomposition methods.

Audience
This book is intended primarily for researchers and graduate students in mathematics, computer sciences, and electrical and other engineering departments. Readers with a background in advanced calculus and linear algebra, as well as prior knowledge in the fundamentals of optimization (some convex analysis, optimality conditions, and duality), will be best prepared for the material.
