Program Description: Many algorithms in mathematical optimisation work on the principle of breaking a complex problem into smaller, computationally tractable pieces and then exploiting the relative simplicity of these smaller pieces as part of an iterative process. For algorithms that use first-order (i.e. gradient) information, operator splitting provides the unifying mathematical framework.

In recent times, there has been an explosion of interest in splitting algorithms due, on one hand, to their ideal suitability for large-scale problems in areas such as machine learning and, on the other hand, to a number of recent practically important mathematical developments such as variance reduction, acceleration, and explicit step size rules. The aim of this workshop is to bring together international experts and Australian researchers working in the field of operator splitting and mathematical optimisation, creating an opportunity to meet, discuss and collaborate. The program is designed to provide an accessible introduction to the field for early-career academics as well as seasoned researchers alike.

Program Structure: TBD

Special Lectures: The workshop will include four week-long mini-courses (2 courses to run in the first week, and 2 courses to run in the second week), each consisting of daily 1h lectures. Each will be given by one of following speakers:

  • Heinz Bauschke (University of British Columbia, Okanagan)
  • Radu Ioan Boţ (University of Vienna)
  • Guoyin Li (UNSW)
  • Akiko Takeda (University of Tokyo)


  • Deadline: TBD
  • Registration is by invitation only. If you are interested to participate in this program, please contact one of the organisers with your CV and research background.
  • Arrival date: 09 February 2025

MATRIX Wine and Cheese Afternoon 11 February 2025
On the first Tuesday of each program, MATRIX provides a pre-dinner wine and cheese afternoon. Produce is locally-sourced to showcase delicacies from the region.
