HANSO is based on BFGS (a surprisingly effective method for nonsmooth optimization, convex or nonconvex, but with no convergence guarantees for nonsmooth functions) and Gradient Sampling (a more computationally demanding method, but with a convergence theory for a broad class of nonsmooth functions). Version 3.0 implements a new variant of the Gradient Sampling algorithm with the stronger guarantees given in a recent survey paper by Burke, Curtis, Lewis, Simoes and myself: https://link.springer.com/book/10.1007%2F978-3-030-34910-3 The code is freely available here: https://cs.nyu.edu/~overton/software/hanso/index.html ------------------------------------------------------- From: Kris ONeill [log in to unmask] Date: September 27, 2021 Subject: New Book, Computed Tomography: Algorithms, Insight, and Just Enough Theory Computed Tomography: Algorithms, Insight, and Just Enough Theory Edited by Per Christian Hansen, Jakob Sauer Jorgensen, and William R. B. Lionheart, With contributions from Martin S. Andersen, K. Joost Batenburg, Yiqiu Dong, Eric Todd Quinto, and Jan Sijbers This book describes fundamental computational methods for image reconstruction in computed tomography (CT) with a focus on a pedagogical presentation of these methods and their underlying concepts. Insights into the advantages, limitations, and theoretical and computational aspects of the methods are included, giving a balanced presentation that allows readers to understand and implement CT reconstruction algorithms. Unique in its emphasis on the interplay between modeling, computing, and algorithm development, it sets the stage for further exploration of CT algorithms. Readers will be able to grasp the underlying mathematical models to motivate and derive the basic principles of CT reconstruction and will gain basic understanding of fundamental computational challenges of CT, such as the influence of noisy and incomplete data. 2021 / xviii + 337 pages / Softcover / 978-1-611976-66-3 / List $89.00 / SIAM Member $62.30 / FA18 SIAM Bookstore: https://my.siam.org/Store/Product/viewproduct/?ProductId=38341835 ------------------------------------------------------- From: Kris ONeill [log in to unmask] Date: September 30, 2021 Subject: New eBook, Lecture Notes for Linear Algebra Lecture Notes for Linear Algebra by Gilbert Strang Lecture Notes for Linear Algebra provides instructors with a detailed lecture-by-lecture outline for a basic linear algebra course.

The research unit covers many aspects of numerics, including approximation theory, numerical integration, numerical (multi)linear algebra, numerical PDEs, uncertainty quantification, optimization and control, discrete optimization and scheduling, network problems, data science, HPC and applied numerical mathematics. The recent surge in advanced techniques for data acquisition gives rise to computational tasks of a complexity far beyond numerical simulation as integrating measurement data in complex models requires specific numerical algorithms. In the simplest setting, finding the 'best' model parameters given some measurement data is an optimization problem. However, demands of practical applications often go far beyond this optimization: one can, for instance, also be interested in quantifying the uncertainty on the resulting optimum, the remaining modeling error with respect to the physical system, or the evolution of the model as a function of time (if data is continuously gathered). The new faculty position aims to strengthen NUMA's position in scientific computing towards a data rich environment. The successful candidate is expected to develop a research program in inverse problems and data assimilation, ensure high-quality education within the area of mathematical engineering, and be prepared to provide scientific, social and administrative services.

Requirements for the PhD position: basically any STEM Master degree (Engineering, Mathematics, Computer Science, ...), decent English level and very good academic record. Knowledge of optimization techniques and software is a plus, as is resilience and a taste for discovery. Project abstract: In the "Fit for 55" climate package the EU has set the world's most ambitious targets for the decarbonification of the energy system (ES). Achieving those objectives requires all the stakeholders to forecast the response of the ES to the possible changes over long timescales. This requires building mathematical models that take into account uncertainties, be multi-level and multi-scale, and properly represent the many combinatorial and nonlinear aspects of the ES. The corresponding monolithic optimization problems are too large to tackle even on the best HPC systems. The only approaches that can possibly tackle problems of this scale and complexity without resorting to dramatic over-simplifications, as customary in current strategic ES models, are decomposition ones, since they are capable of exploiting all the several forms of structure (scenarios, geographical and temporal scales) they possess. However, standard modelling systems do not support implement multi-level, heterogeneous decomposition approaches.

The topic of the PhD thesis is "Nodal finite-difference micromagnetics on distributed systems". The aim of this PhD project is the development and implementation of a novel nodal finite-difference approach for micromagnetics that will combine the benefits of the finite-element method and the finite-difference method. Namely, this hybrid method will allow for a rigorous description of multiphase magnets by a variational approach related to finite elements while making use of fast convolution techniques known from finite- difference micromagnetics. State-of the art tensor libraries such as TensorFlow/Pytorch will be used in order to implement the novel approach, enabling the use of modern distributed hardware such as multi GPU machines. Computational micromagnetics has a long history as a valuable tool for the theoretical investigation of magnetic systems at the micron scale. Despite massive advances in computing power, today's micromagnetic simulations are still restricted to the micron sized systems since the micromagnetic model calls for a very fine spatial discretization in the single-digit nanometer regime. The FWF project "Very largescale distributed micromagnetic research tools" aims to push the boundaries of micromagnetic simulations towards larger systems by introducing recent algorithms and technologies to numerical micromagnetics which are particularly suited for d istributed systems and novel hardware. This position is funded for 3 years and is paid with a monthly gross salary of 2 237.60E UR for 30 h/week. If you are interested in this PhD project please send your application documents ( motivational letter, CV, GitHub profile, ...) to Claas Abert ( [log in to unmask]). ------------------------------------------------------- From: Gabriel Lord [log in to unmask] Date: September 27, 2021 Subject: PhD Position, Numerical and Computational Analysis for Neuroscience There is an opening for a 4 year PhD position at Radboud University, Nijmegen, The Netherlands .

Detailed description: The "Fit for 55" package has set ambitious emission reduction targets that can only be achieved with a multifactorial approach. Local Public Transport (LPT) already offers much lower emissions per passenger / km than owned cars. Increase penetration of electric cars will lead, at constant rates, to a reduction in emissions; but the electrification of the LPT fleet and the increase in the share of multimodal journeys would lead to much greater reductions. However, electrifying the LPT entails considerable problems, related e.g. to the need for frequent charging stops, which could lead to cost increases or decreases in Quality of Service (QoS), and therefore to a decrease in the use of LPT which would be detrimental to the decarbonisation objectives. Duration: Three years. The deadline for the application is October 15, 2021. The selection process is expected to be performed swiftly thereafter and the activity to start before year's end. Requirements for the PhD position: basically any STEM Master degree (Engineering, Mathematics, Computer Science, ...), decent English level and very good academic record.
