This package contains limited memory trust- region and line-search algorithms implemented in MATLAB. The algorithms are described in "On Efficiently Combining Limited Memory and Trust-Region Techniques", Mathematical Programming Computation (2017) Vol. 9, no 1, pp. 101-134 https://doi.org/10.1007/s12532-016-0109- 7. To download the package, you may want to follow the link http://gratton.perso.enseeiht.fr/LBFGS/index.html The package contains the following algorithms: - LBFGS_TR.m. Limited memory line-search algorithm L-BFGS that takes a trial step along the quasi-Newton direction inside the trust region; - LBFGS_MTBT.m. Limited memory line-search algorithm L-BFGS based on the More-Thuente line search and the initial step is obtained using backtrack; - LBFGS_MT.m. Limited memory line-search algorithm L-BFGS based on the More-Thuente line search; - LMTR_BWX_MS.m. Limited memory trust-region algorithm BWX-MS.

R. Werner werner@mpi-magdeburg.mpg.de Date: December 06, 2018 Subject: Software Release, MORLAB 4.0 Version 4.0 of the MORLAB, Model Order Reduction LABoratory, toolbox has been released. The toolbox is a collection of MATLAB and Octave routines for model order reduction of linear dynamical systems based on the solution of matrix equations. The implementation is based on spectral projection methods, e.g., methods based on the matrix sign function and the matrix disk function. The toolbox contains implementations for standard, descriptor and second-order systems: - Modal truncation (MT) - Balancing related methods (BT, BST, FLBT, LQGBT, PRBT, BRBT, HINFBT, TLBT) - Hankel-norm approximation (HNA) Also, matrix equation solvers based on the matrix sign function as well as further subroutines for the analysis of linear dynamical systems are provided in the MORLAB toolbox. For more details on this software, see: http://www.mpi-magdeburg.mpg.de/projects/morlab ------------------------------------------------------- From: Martin Stynes m.stynes@csrc.ac.cn Date: December 07, 2018 Subject: New Book, Convection-Diffusion Problems Convection-Diffusion Problems: An Introduction to Their Analysis and Numerical Solution by Martin Stynes & David Stynes AMS Graduate Studies in Mathematics Vol. 196 Many physical problems involve diffusive and convective (transport) processes. When diffusion dominates convection, standard numerical methods work satisfactorily. But when convection dominates diffusion, the standard methods become unstable, and special techniques are needed to compute accurate numerical approximations of the unknown solution. This convection-dominated regime is the focus of the book. After discussing at length the nature of solutions to convection-dominated convection-diffusion problems, the authors motivate and design numerical methods that are particularly suited to this class of problems. At first they examine finite-difference methods for two-point boundary value problems, as their analysis requires little theoretical background. Upwinding, artificial diffusion, uniformly convergent methods, and Shishkin meshes are some of the topics presented. Throughout, the authors are concerned with the accuracy of solutions when the diffusion coefficient is close to zero. Later in the book they concentrate on finite element methods for problems posed in one and two dimensions. This lucid yet thorough account of convection-dominated convection- diffusion problems and how to solve them numerically is meant for beginning graduate students, and it includes a large number of exercises. An up-to-date bibliography provides the reader with further reading.
