Workshop on the Intersections of Computation and Optimisations – WICO: second announcement. 

Workshop on the Intersections of Computation and Optimisations – WICO 

MoCaO (Mathematics of Computation and Optimisation) is planning a new workshop on the 22nd to the 25th of November 2021, which is sponsored by the ANU, UNSW and AMSI.

This workshop intends to bring together researchers from the areas of computation, optimisation, computing sciences and engineering interested in the cross- fertilization of ideas around the interfaces of computational mathematics and optimisation:

Workshop Format

The workshop will be held online using Zoom and Spatial Chat (for formal and informal interactions). Depending on COVID restrictions, we may also have some hybrid participation via live gatherings at some regional locations (including the mathematics department at the ANU in Canberra). Further announcement will be made closer to the event.

Keynotes Speakers:

Some keynotes may present in person (streamed online) and others will engage totally online in a remote format. In addition to their keynote presentations, keynotes who will be invited to give an informal discussion session post presentation.

Prof Gerlind Plonka-Hoch (University of Goettingen, Germany)

Prof. Frances Kuo (UNSW)

Prof Stefan Wild (Argonne, USA)

Prof Stephen Wright (Wisconsin, USA) 

Prof. Ian Turner (QUT)

Prof. Claudia Sagastizabal (IMECC-Unicamp and CEMEAI, Brazil)

Prof Martin Berggren (Umeå University, Sweden)

Important dates:

Registration is Free and Now Open: ANU WICO event page

Workshop Dates: 22/11/2021 to 25/11/2021

Future Announcements and Grants:

We also wish to draw female participants attention to the possibility of applying for the WIMSIG Cheryl E. Praeger Travel Award (support for attending conferences/visiting collaborators) and/or the WIMSIG Anne Penfold Street Awards (support for caring responsibilities while attending conferences/visiting collaborators).

VA & Opt Webinar: Walaa Moursi

Title: The Douglas-Rachford algorithm for solving possibly inconsistent optimization problems

Speaker: Walaa Moursi (University of Waterloo)

Date and Time: Wed Sep 15, 11:00 AEST (Register here for remote connection via Zoom)

Abstract: 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 classical and highly successful splitting method to find minimizers of the sum of two (not necessarily smooth) convex functions. While the underlying theory has matured, one case remains a mystery: the behaviour of the shadow sequence when the given functions have disjoint domains. Building on previous work, we establish for the first time weak and value convergence of the shadow sequence generated by the Douglas–Rachford algorithm in a setting of unprecedented generality. The weak limit point is shown to solve the associated normal problem which is a minimal perturbation of the original optimization problem. We also present new results on the geometry of the minimal displacement vector.

VA & Opt Webinar: Andrew Eberhard

Title: Bridges between Discrete and Continous Optimisation in Stochastic Programming

Speaker: Andrew Eberhard (RMIT University)

Date and Time: June 30th, 2021, 17:00 AEST (Register here for remote connection via Zoom)

Abstract: For many years there has been a divide between the theoretical under pinning of algorithmic analysis in discrete and continuous optimisation. As a case study, stochastic optimisation provides a classic example. Here the theoretical foundations of continuous stochastic optimisation lies in the theory of monotone operators, operator splitting and nonsmooth analysis, none of which appear to be applicable to discrete problems. In this talks we will discuss the application of ideas from continuous optimisation and variational analysis to the study of progressive hedging like methods for discrete optimisation models. The key to the success of such approaches is the acceptance of the existence of MIP and QMIP\ solvers that can be integrated in to analysis as “black box solvers” that return solutions within a broader algorithmic analysis. Here methods more familiar to continuous optimisers and nonsmooth analysts can be used to provide proofs of convergence of both primal and dual methods. Unlike continuous optimisation there still exists separate primal and dual methods and analysis in the discrete context. We will discuss this aspect and some convergent modifications that yield robust and effective versions of these methods, long with numerical validation of their effectiveness.
