"Expanding the reach of splitting methods"Sagastizábal, ClaudiaMany splitting algorithms popular in large-scale or distributed optimization are derived from the Spingarn partial inverse framework. The proximal decomposition method of Philippe Mahey and his co-authors is a paradigmatic example. We will discuss new insight gained by examining this approach from the dual perspective of nonsmooth optimization. Joint work with Felipe Atenas, Theo Molfessis and Mikhail Solodov |
