Subject: HSL 2023, Mathematical Software Library

The Computational Mathematics Group at the UKRI-STFC Rutherford
Appleton Laboratory is pleased to announce the latest release of the
internationally renowned HSL Mathematical Software Library.

This year marks the 60th anniversary of the first release in 1963 of
what was then the Harwell Subroutine Library. Although originally a
general- purpose mathematical library, in recent times HSL has
specialised in providing state-of-the-art routines for handling
large-scale sparse matrix calculations efficiently and reliably. A
brief historical account of HSL@60, of general interest, can be found

Highlights of HSL 2023 include:
- HSL_MA85 - Solve large-scale diagonally-weighted linear least-
squares problems.
- HSL_MI35 - An incomplete factorization preconditioner for weighted
sparse linear least-squares problems.
- HSL_MC81 - Use randomized algorithms to compute a low-rank matrix
approximation for SPD or general m x n matrices.
- New C interfaces are available for HSL_MA57 (solve sparse symmetric
system via a multifrontal method) and HSL_MI28 (incomplete Cholesky
factorization preconditioner).
- All MATLAB interfaces are now also available on Windows and MacOS.
- JuliaHSL - an interface to HSL packages from Julia.
- CoinHSL - improved support for non-Linux users of the HSL solvers
within IPOPT.

HSL 2023 is freely available to academic staff and students for
personal use in teaching and research. Commercial licences are also

Subject: New Book, Introduction to Nonlinear Optimization, Second Edition

Introduction to Nonlinear Optimization: Theory, Algorithms, and
Applications with Python and MATLAB, Second Edition by Amir Beck

Built on the framework of the successful first edition, this book
serves as a modern introduction to the field of optimization. The
author's objective is to provide the foundations of theory and
algorithms of nonlinear optimization as well as to present a variety
of applications from diverse areas of applied sciences.

Introduction to Nonlinear Optimization gradually yet rigorously builds
connections between theory, algorithms, applications, and actual
implementation. The book contains several topics not typically
included in optimization books, such as optimality conditions in
sparsity constrained optimization, hidden convexity, and total least
squares. Readers will discover a wide array of applications such as
circle fitting, Chebyshev center, the Fermat-Weber problem, denoising,
clustering, total least squares, and orthogonal regression. These
applications are studied both theoretically and algorithmically,
illustrating concepts such as duality. Python and MATLAB programs are
used to show how the theory can be implemented. The extremely popular
CVX toolbox (MATLAB) and CVXPY module (Python) are described and used.

Subject: New Book, Moment and Polynomial Optimization

Moment and Polynomial Optimization by Jiawang Nie

Moment and polynomial optimization is an active research field used to
solve difficult questions in many areas, including global
optimization, tensor computation, saddle points, Nash equilibrium, and
bilevel programs, and it has many applications. The author synthesizes
current research and applications, providing a systematic introduction
to theory and methods, a comprehensive approach for extracting
optimizers and solving truncated moment problems, and a creative
methodology for using optimality conditions to construct tight
Moment-SOS relaxations. This book is intended for applied
mathematicians, engineers, and researchers entering the field. It can
be used as a textbook for graduate students in courses on convex
optimization, polynomial optimization, and matrix and tensor

Subject: New Book, The Sequential Quadratic Hamiltonian Method

The Sequential Quadratic Hamiltonian Method
Solving Optimal Control Problems
by Alfio Borzi

The sequential quadratic hamiltonian (SQH) method is a novel numerical
optimization procedure for solving optimal control problems governed
by differential models. It is based on the characterisation of optimal
controls in the framework of the Pontryagin maximum principle (PMP).
The SQH method is a powerful computational methodology that is capable
of development in many directions. The book discusses its analysis and
use in solving nonsmooth ODE control problems, relaxed ODE control
problems, stochastic control problems, mixed-integer control problems,
PDE control problems, inverse PDE problems, differential Nash game
problems, and problems related to residual neural networks. This book
may serve as a textbook for undergraduate and graduate students, and
as an introduction for researchers in sciences and engineering who
intend to further develop the SQH method or wish to use it as a
numerical tool for solving challenging optimal control problems and
for investigating the Pontryagin maximum principle on new optimisation

Provides insight into mathematical and computational issues concerning
optimal control problems, while discussing many differential models of
interest in different disciplines. Suitable for undergraduate and
graduate students and as an introduction for researchers in sciences
and engineering. Accompanied by codes which allow the reader to apply
the SQH method to solve many different optimal control and
optimisation problems.

multi-fidelity methods or inverse problems on applications in physics
or engineering.

The activities of the MatMat group revolve around understanding modern
materials simulations from a mathematical point of view =13 and to come
up with ways to make such simulations faster, quantify their errors or
make them more reliable. You will become part of a young and energetic
team, fully integrated with both the mathematics and the materials
institutes as well as cross-disciplinary initiatives. The goal of this
project will be to investigate the opportunities for uncertainty
quantification in materials modelling enabled by modern tools such as
algorithmic differentiation (AD). Due to the rather unexplored nature
of this topic, a variety of research questions could be tackled,
depending on your interests and prior background. As part of the
project you will collaborate with researchers from diverse backgrounds
and acquire the broad skillset required to become an independent
researcher in this exciting field.

Screening of candidates starts 1st August 2023 and continues until the
position is filled.

The University of Birmingham has recently been announced as new
academic partner of the UK Met Office. As part of the partnership, we
are offering a small number of fully-funded studentships to work on
co- created projects in relevant areas across the two organisations.
The areas are:
- Advancing Observations: Working towards a step change in
observational capabilities, realising the value of third party and
opportunistic observations to address growing needs.
- Fusing Simulation with Data Science: Exploring the use of new and
evolving data science methods such as artificial intelligence,
machine learning and advanced data assimilation for weather and
climate prediction and impact-based services
- Hazard to Decision Making: Using an interdisciplinary approach to
increase understanding of the impacts of hazards and to develop
better impact-based services.
- Capturing Environmental Complexity: Extend applied environmental
prediction capabilities with a focus on cities, air quality, the
water cycle, and carbon and nitrogen cycles.

These are aligned to the latest Met Office research and innovation
strategy. More details on each area can be found here:

We are looking for applicants across these four areas with a
willingness to flexibly shape a PhD to start in Autumn 2023.
Applicants are expected to include a 1000 word (max.) research
proposal focussed on one of the four above areas and aligned to the
Met Office research and innovation strategy as part of their
application. This will form the basis for further discussion and will
be used to assign a supervisory team from the University and the Met
Office. The proposal will then evolve via a co-creation process to
ensure that it is mutually beneficial to all. Please note, that
during this process the proposal could change considerably and
therefore, a willingness to work more generally within the chosen area
is an essential requirement.
