An in-depth exploration of Anderson Acceleration unites recent theoretical insights with practical methods to enhance nonlinear PDE solvers used in science, engineering, and economics. It details convergence for diverse operators, innovative filtering strategies, and blending AA with Newton’s method, supported by proofs and code.
Research on the Anderson Acceleration (AA) has exploded in the last 15 years. This book brings together these recent fundamental results applied to nonlinear solvers for PDEs, which are ubiquitous across mathematics, science, engineering, and economics as predictive models for a vast quantity of important phenomena. Coverage includes:

• AA convergence theory for both contractive and non-contractive operators,
• filtering techniques for AA, showing how the convergence theory can be fit to various application problems, and
• AA’s effect on sublinear convergence, and
• how AA can be best combined with Newton’s method.
