In many different fields such as optimization, the performance of a method is often characterized by its rate of convergence. However, accelerating an algorithm requires a lot of knowledge about the problem’s structure, and such improvement is done on a case-by-case basis. Many accelerated schemes have been developed in the past few decades and are massively used in practice. Despite their simplicity, such methods are usually based on purely algebraic arguments and often do not have an intuitive explanation. Recently, heavy work has been done to link accelerated algorithms with other fields of science, such as control theory or differential equations. However, these explanations often rely on complex arguments, usually using non-conventiona...
