A new IEEE 754 standard for floating-point arithmetic in an ever-changing world. SIAM News, July/August 2021. ------------------------------------------------------- From: Kris ONeill [log in to unmask] Date: August 24, 2021 Subject: New Book, Lectures on Stochastic Programming: Modeling and Theory Lectures on Stochastic Programming: Modeling and Theory, Third Edition By Alexander Shapiro, Darinka Dentcheva, Andrzej Ruszczynski An accessible and rigorous presentation of contemporary models and ideas of stochastic programming, this substantially revised edition focuses on optimization problems involving uncertain parameters for which stochastic models are available. It presents a modern theory of stochastic programming, including expanded and detailed coverage of sample complexity, risk measures, and distributionally robust optimization. It adds two new chapters that provide readers with a solid understanding of emerging topics; updates Chapter 6 to now include a detailed discussion of the interchangeability principle for risk measures; and presents new material on formulation and numerical approaches to solving periodical multistage stochastic programs. 2021 / xv + 525 pages / Hardcover / 978-1-611976-58-8 / List $104.00 / SIAM Member $72.80 / MO28 SIAM Bookstore: https://my.siam.org/Store/Product/viewproduct/?ProductId=38258337 ------------------------------------------------------- From: Kris ONeill [log in to unmask] Date: August 24, 2021 Subject: New Book, Numerical Continuation and Bifurcation in Nonlinear PDEs Numerical Continuation and Bifurcation in Nonlinear PDEs by Hannes Uecker This book provides a hands-on approach to numerical continuation and bifurcation for nonlinear PDEs in 1D, 2D, and 3D. Partial differential equations (PDEs) are the main tool to describe spatially and temporally extended systems in nature. PDEs usually come with parameters, and the study of the parameter dependence of their solutions is an important task. Letting one parameter vary typically yields a branch of solutions, and at special parameter values, new branches may bifurcate. After a concise review of some analytical background and numerical methods, the author explains the free MATLAB package pde2path by using a large variety of examples with demo codes that can be easily adapted to the reader's given problem. 2021 / xvi + 364 pages / Softcover / 978-1-611976-60-1 / List $89.00 / SIAM Member $62.30 / OT174 SIAM Bookstore: https://my.siam.org/Store/Product/viewproduct/?ProductId=38341844 ------------------------------------------------------- From: Jakub Sistek [log in to unmask] Date: August 27, 2021 Subject: Domain Decomposition Methods, Czech Republic, Jul 2022 The 27th International Conference on Domain Decomposition Methods (DD27) will be held in Prague, Czech Republic during July 25-29, 2022.
