Subject: Lagrange Prize in Continuous Optimization


The Lagrange Prize in Continuous Optimization will be awarded jointly
by SIAM and the Mathematical Optimization Society (MOS) at the 2021
SIAM Annual Meeting. We are now accepting nominations, see
https://evoq-eval.siam.org/prizes-recognition/joint-prizes/detail/lagrange-
prize-in-continuous-optimization

The Lagrange Prize in Continuous Optimization is awarded ever three
years for an outstanding contribution in the area of continuous
optimization published in the six calendar years prior to the award
year. The MOS administers the prize and it is awarded jointly by MOS
and SIAM.

Eligibility Criteria: The award is based primarily on the work's
mathematical quality, significance, and originality. Clarity and
excellence of the exposition and the value of the work in practical
applications may be considered as secondary attributes. The extended
period of six years reflects the fact that the value of fundamental
work cannot always be immediately assessed.

The work must have been published as the final publication of the main
result(s) within the six calendar years preceding the award year. The
work should be published as an article in a peer-reviewed journal, or
other peer-reviewed publication, intended to publish final papers
only; or as a monograph publishing original results.

For the 2021 award, the work must have been published between the
dates of January 1, 2015 - December 31, 2020.

Nomination Deadline: October 15, 2020

Selection Committee:
Sven Leyffer (Chair), Argonne National Laboratory
Xiaojun Chen, Hong Kong Polytechnic University
Etienne de Klerk, University of Tilberg, The Netherlands
Philip Gill, University of California San Diego

Subject: New Book, Linear Algebra for Everyone


2020 / xii + 356 pages / Hardcover / 978-1-7331466-3-0
Wellesley-Cambridge Press / List 85.00 / Individuals 57.00

This linear algebra textbook has a new start. For small matrices with
integer entries, everyone can recognize when a column is a combination
of earlier columns. Then A = CR : independent columns in C times
coefficients in R give all columns in A. From examples come the key
ideas of rank and column space. When all columns are multiples of one
column in C, the rank is 1 and R has one row : column rank = row rank.
This new start leads to a better finish. The goal is the SVD: perfect
bases for the column space and nullspace of A and A^T. This is a
textbook for linear algebra courses everywhere. Please see
http://math.mit.edu/everyone for the Contents and the Preface.

Subject: Data Assimilation and Uncertainty Quantification, ONLINE, Sep 2020


Uncertainty Quantification (UQ) includes the propagation of
uncertainty from inputs to outputs through simulators, as well as
inverse problems resulting from the calibration of models against
observations. One key tool is building emulators (surrogate
statistical models) to replace computationally expensive
simulators. Data assimilation (DA) synergizes computer simulations and
real-world data, e.g. from weather prediction to hazard modelling,
urban analytics and biological science, with observations used to
update simulations in real time. With the interaction between forward
simulations and information-driven methods, techniques for UQ and DA
are specifically challenged by the scale of problems that exascale
computing will enable. Developing efficient UQ and DA algorithms will
also be a major challenge, with close collaborations between RSEs and
researchers necessary.

This online Zoom-hosted workshop is part of an EPSRC funded project on
Exascale Computing for Systems Level Engineering. This is an
international workshop, free to attend and will take place on 24-25
September 2020 (13:00-17:00 BST). Registration is required. Further
details, including the link to register, are available at

Subject: Bilevel Optimization, ONLINE, Oct 2020


Autumn School on Bilevel Optimization (October 12- 14, 2020)

Bilevel optimization problems have attracted considerable attention
over the last decades since their structure allows the modeling of a
large number of real-life problems involving two types of
decision-makers, a leader and a follower, interacting sequentially in
a hierarchical setting. This rather young and highly active field at
the interfaces between mathematical optimization, computer science,
and operations research has grown a lot in the last years. The studied
problems are constrained optimization problems in which some
constraints specify that a subset of variables constitutes an optimal
solution of another (nested) optimization problem. Bilevel problems
constitute a class of very difficult problems because they are
inherently nonconvex and nondifferentiable. They are already NP-hard
even if both levels are linear problems.

In the ALOP (https://alop.uni-trier.de) autumn school on bilevel
optimization we will have introductory talks on the topics of linear
as well as mixed-integer linear bilevel problems and on the relation
between bilevel optimization, MPECs, and variational inequalities. The
confirmed speakers are Martine Labbe (Universite Libre de Bruxelles),
Ivana Ljubic (ESSEC Business School of Paris), and Didier Aussel
(Universite de Perpignan).

Due to the current circumstances, the autumn school will take place
online via Zoom meetings. Registration and participation are free of
charge and we will provide certificates of participation. The
registration deadline is September 28, 2020. We also plan to have an
elevator pitch session, where all participants can present their
current research in short talks of 3 minutes.

All relevant information and updates can be found at
https://alop.uni-trier.de/event/autumn-school-on-bilevel-optimization.

Subject: Sparse Days at Cerfacs, ONLINE, Nov 2020


Sadly, because of the pandemic, we will not be able to have a normal
face-to-face Sparse Days at Cerfacs this year. We will be holding an
online version from 3pm to 7pm on 23 and 24 November. The timing is
chosen to accommodate participants from North America since, at normal
Sparse Days, we have a good representation from there.

A registration form is available on the conference website
https://sparsedays.cerfacs.fr/en where you can also submit a title and
an abstract for any proposed talk. We will probably be using the
Webex system and will post details about how to connect to all people
who register.

Although the meeting is now online, we plan to have the same flavour
as for previous Sparse Days. That is to say having a relaxed
programme with short talks and scheduled coffee breaks for less formal
discussion. Sadly, there will not be a Conference Dinner this year.
We already have arranged for talks by a few well known senior people
but as usual, have plenty of room and encouragement for students and
young researchers.

Although we have set a deadline of 6 November 2020, it would be very
good if you could register well before then, especially if you are
planning on giving a talk.

As usual, any talk that even loosely fits our conference title is
welcome. In order to keep a relaxed format and to accommodate all
anticipated talks within the programme, we would encourage short talks
(20 minutes including questions), but are happy to include longer or
shorter ones on request.

Subject: ECCOMAS Young Investigators Conference, Spain, Jul 2021


The next ECCOMAS Young Investigators Conference will be hold in
Valencia (SPAIN) next 7th-9th July 2021. The main goal of the YIC 2021
conference is to bring together young investigators and experienced
researchers, and provide a forum for discussing the state-of-the-art
on Computational Methods and Applied Sciences. Contributions to any
topic related to computational science and engineering are welcome.
It is our pleasure to invite you to organize a Minisymposium (MS) in a
topic of your interest. The MS must include at least four invited
presentations. We would appreciate receiving your one page MS
proposal by 30th September at yic2021@upv.es .
