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.

Title: Nonsmooth DC optimization: recent developments
Speaker: Adil Bagirov (Federation University)
Date and Time: June 23rd, 2021, 17:00 AEST (Register here for remote connection via Zoom)
Abstract: In this talk we consider unconstrained optimization problems where the objective functions are represented as a difference of two convex (DC) functions. Various applications of DC optimization in machine learning are presented. We discuss two different approaches to design methods of nonsmooth DC optimization: an approach based on the extension of bundle methods and an approach based on the DCA (difference of convex algorithm). We also discuss numerical results obtained using these methods.
Title: Error bounds, amenable cones and beyond
Speaker: Bruno F. Lourenço (Institute of Statistical Mathematics)
Date and Time: June 16th, 2021, 17:00 AEST (Register here for remote connection via Zoom)
Abstract: In this talk we present an overview of the theory of amenable cones, facial residual functions and their applications to error bounds for conic linear systems. A feature of our results is that no constraint qualifications are ever assumed, so they are applicable even to some problems with unfavourable theoretical properties. Time allowing, we will discuss some recent findings on the geometry of amenable cones and also some extensions for non-amenable cones.
The Research Fellow is expected to conduct world-class research and provide training for research students working in industrial optimisation as a key appointee in a newly established ARC Training Centre in Optimisation Technologies, Integrated Methodologies and Applications (OPTIMA). The research program involves a focus on model-based and black-box optimisation methodologies of relevance to a broad range of industry partner optimisation challenges. A
multidisciplinary approach is expected, drawing from techniques developed in mathematics, computer science, statistics, engineering, and economics.
