About the workshop

The interest in modern methods of very large scale optimization has recently grown remarkably due to their application in diverse practical problems including machine learning, inverse problems in statistics and signal/image processing, energy, finance, telecommunication, optimal control, and many others. This workshop will consist of several presentations by leading researchers in the field, with the aim of promoting an exchange of ideas to advance the state of the art in this area.
The workshop will have a particular focus on Alternating Direction Method of Multipliers (ADMM).
The event is long overdue (it was initially planned for June 2020).


Thursday 19th and Friday 20th May 2022.
