On the Douglas–Rachford Algorithm for Solving Possibly Inconsistent Optimization Problems
On the Douglas–Rachford Algorithm for Solving Possibly Inconsistent Optimization Problems
More than 40 years ago, Lions and Mercier introduced in a seminal paper the Douglas–Rachford algorithm. Today, this method is well-recognized as a classic and highly successful splitting method to find minimizers of the sum of two (not necessarily smooth) convex functions. Whereas the underlying theory has matured, one case …
