Abstract: The AAA algorithm, introduced in 2018, computes best or near-best rational approximations to functions or data on subsets of the real line or the complex plane. It is much faster and more robust than previous algorithms for such problems and has been used in many applications since its appearance, including the numerical solution of Laplace, Poisson, and biharmonic PDE problems in irregular domains. AAA has also been extended in new directions and seems likely to be a tool of lasting importance in the future.
