Hybrid input-output algorithm

The Hybrid Input-Output (HIO) algorithm is a computational approach often used in the context of optimization problems, particularly in the field of signal processing, image reconstruction, and iterative algorithms for phase retrieval. While the term "Hybrid Input-Output" may be used in various contexts, it is frequently associated with methods that combine different iterative techniques (input-output algorithms) to achieve improved convergence properties or performance in solving specific problems.
