Links to machine learning will be emphasized in multiple applications. Opportunities and challenges will be discussed. He served in multiple academic positions from to between Alexandria University and Rice University before joining ExxonMobil. In the last ten years, his focus has been on the application of machine learning and optimization methods to production optimization problems. In this talk, we will give an overview over optimization problems under uncertainty as they appear in energy management, together with global solution approaches.
One way of protecting against uncertainties that occur in real-world applications is to apply and to develop methodologies from robust optimization. The latter takes these uncertainties into account already in the mathematical model. The task then is to determine solutions that are feasible for all considered realizations of the uncertain parameters, and among them one with best guaranteed solution value. We will introduce a number of electricity and gas network optimization problems for which robust protection is appropriate. Already for simplified cases, the design of algorithmically tractable robust counterparts and global solution algorithms is challenging.
As an example, the stationary case in gas network operations is complex due to non-convex dependencies in the physical state variables pressures and flows. In the robust version, two-stage robust problems with a non-convex second stage are to be solved, and new solution methodologies need to be developed. We will highlight robust optimization approaches and conclude by pointing out some challenges and generalizations in the field. The main focus of Frauke Liers' research is on the development, the analysis and the implementation of global solution approaches in mixed-integer nonlinear optimization.
In particular, she is active in robust optimization and puts emphasis on the development of algorithmically tractable robust counterparts for problems under uncertainty. Her work is motivated by optimization tasks with applications in logistics, in operations research, in engineering, and in the natural sciences. She received her doctorate degree in and the Habilitation degree from the University of Cologne in She is principal investigator in the Collaborative Research Center on mathematical modelling, simulation and optimization using the example of gas networks.

Primal-dual interior-point methods for semidefinite programming, as implemented in widely used solvers, rely on the elegant theory of self-scaled barriers and the property that the dense symmetric positive semidefinite matrices form a symmetric convex cone. In applications it is very common that the constraints in a semidefinite program are sparse.
It is natural to pose such problems as conic optimization problems over cones of sparse positive semidefinite matrices, in order to exploit theory and algorithms from sparse linear algebra. Examples of this approach are the splitting techniques based on decomposition theorems for chordal sparsity patterns, which have been applied successfully in first-order methods and interior-point algorithms. However sparse semidefinite matrix cones are not symmetric, and conic optimization algorithms for these cones lack the extensive theory behind the primal-dual methods for dense semidefinite optimization.
The talk will explore new formulations of primal-dual interior-point methods for sparse semidefinite programming. It will mostly focus on the important special case of chordal sparsity patterns that define homogeneous convex cones. He obtained the Electrical Engineering degree and a Ph.

Short biography Dr. Shanbhag, Pennsylvania State University, USA Abstract We address two sets of fundamental problems in the context of equilibrium problems: i Of these, the first pertains towards the development of existence statements for stochastic variational inequality and complementarity problems. Short biography Uday V. Projections, proximal maps, and similar techniques provide powerful tools to convert variational inequalities and stationarity conditions into nonsmooth operator equations. These then enable the application of semismooth Newton methods, which belong to the most successful algorithms for inequality constrained problems with PDEs.
Nonsmoothness also arises in problems with equilibrium constraints, such as MPECs, or with bilevel structure. This is particularly apparent when reduced problems are generated via solution operators of subsystems. Similarly, nonlinear PDEs, even if looking smooth at first sight, often pose challenges regarding the differentiability of the solution operator with respect to parameters such as control or shape. There are also important applications where nonsmoothness arises naturally in the cost function, for instance in sparse control or when risk measures like the CVaR are used in risk-averse PDE-constrained optimization.
Also other approaches for PDE-constrained optimization under uncertainty exhibit nonsmoothness, e. Heinz Bauschke, University of British Columbia, Canada Abstract The Douglas-Rachford algorithm is a popular method for finding minimizers of sums of nonsmooth convex functions; or, more generally, zeros of sums of maximally monotone operators. Curtis, Lehigh University, USA Abstract One of the most important developments in the design of optimization algorithms came with the advent of quasi-Newton methods in the s. Short biography Frank E.

Three Basic Optimization Algorithms. Back Matter Pages About this book Introduction The book gives a detailed and rigorous treatment of the theory of optimization unconstrained optimization, nonlinear programming, semi-infinite programming, etc. The fundamental results of convexity theory and the theory of duality in nonlinear programming and the theories of linear inequalities, convex polyhedra, and linear programming are covered in detail. Over two hundred, carefully selected exercises should help the students master the material of the book and give further insight.
Some of the most basic results are proved in several independent ways in order to give flexibility to the instructor. The first chapter of the book introduces the necessary differential calculus tools used in the book. The book is suitable as a textbook for a first or second course in optimization at the graduate level. It is also suitable for self-study or as a reference book for advanced readers.
