8- Sparse days III, Saint Girons , June 29th - July 2nd, 2015
(source : J.-B. Caillau)

The conference is organized by IRIT and CERFACS researchers with an international management committee comprising general chairs
James Demmel (University of Berkeley), Jack Dongarra (University of Tennessee), Iain Duff (RAL and CERFACS-IRIT common lab), and
Patrick Amestoy (INPT-IRIT). The local organizer chair is Pierre-Henri Cros (IRIT).

In any large-scale numerical computation in the context of large, complex and hierarchical computers, one has to understand the algorithmic choices that have to be made. In this context, both sparse linear algebra kernels together with dense linear kernels are the key to enable other numerical libraries in the software stack to achieve high computational efficiency.
The focus of the conference in St Girons will be on these kernel topics although there will be dedicated sessions on optimization and on the themes of the four workshops of the CIMI semester: - Low-rank approximations for high performance sparse solvers
- Innovative clustering methods for large graphs and block methods
- Parallel methods for time dependent problems
- Advances in optimization with application to data assimilation

11- Fourteenth annual "Modeling and OPtimization: Theory and Applications" (MOPTA) conference, Lehigh University, Bethlehem, Pennsylvania, July 20-22, 2015
(source : M. Théra)

MOPTA aims at bringing together a diverse group of people from both
discrete and continuous optimization, working on both theoretical and
applied aspects.  There will be invited plenary talks from distinguished
speakers as well as organized sessions and contributed talks, spread
over three days.  Our target is to provide a diverse set of exciting new
developments from different areas of optimization research while at the
same time providing a setting which will allow increased interaction
among the participants.  We aim to bring together researchers from both the theoretical and applied communities in the framework of a
medium-scale event who do not usually have the chance to interact in
larger meetings.

We welcome contributed talks, and we are also very interested in hearing from people who could organize a session centered around one of their topics of expertise. MOPTA sessions have 3 speakers, with 30 mins per presentation including Q&A's. Speakers will be kindly asked
to submit their abstract on the MOPTA website. The deadline for abstract submission is May 1.

Confirmed plenary speakers:
* Alper Atamtürk (University of California-Berkeley)
* Amir Beck (Technion - Israel Institute of Technology)
* Mirjam Dür (University of Trier)
* Eugene Feinberg (SUNY)
* Ravi Mazumdar (Waterloo)
* Luis Nunes Vicente (Universidade de Coimbra)
* Tong Zhang (Rutgers University)

Please contact Alexander Stolyar (als714@lehigh.edu)
or Martin Takac (Takac.MT@gmail.com) if you would like to organize a session for MOPTA.

12- International Workshop “Variational Analysis and Applications”, ERICE,August 28 – September 5, 2015
(source : M. Théra)

The workshop aims at presenting state-of-the-art and current research directions in variational analysis and partial differential equations and systems.

Variational analysis encompasses a large area of modern mathematics, including the classic calculus of variations, the theories of perturbation, approximation, subgradient, subderivatives, set convergence and variational inequalities. Originating with the Signorini problem, about 5 decades ago, variational inequalities have undergone great development and influence both in the progress of variational analysis, and in applications to mathematical physics and, more recently, to engineering, statistics, economics, financial networks and generalized complementarity problems.

In particular, several classical and new theories have received a strong impulse for effective solutions to until-now unsolved problems. These theories include: evolutionary projected dynamical systems, infinite dimensional duality, minimax problems, existence of solutions for Jacobian and Hessian equations, optimal control, differential inclusions, dual conditions for nonconvex functions, moving boundary variational problems, inverse variational inequalities, degenerate transmission problems, obstacle problems with measurable coefficients, second order optimality conditions, infima over sub-level sets, relaxation methods in Hilbert spaces, new energy inversion in saddle point problems, stochastic variational inequalities.

The workshop aims at offering a review of the results achieved in the above research themes, specifying the used methods and pointing out the open problems together with outlines of the new research trends in the principal topics of variational analysis and applications.

The sessions of September 3-4 will be dedicated to Professor Antonino Maugeri in the occasion of his 70th birthday.

During the opening ceremony of the International Workshop, a Gold Medal in honour of Guido Stampacchia will be assigned for the fifth time, after an international competition, to a young mathematician, whose age be not greater than 35 years at the date of December 31st 2015, for his scientific contribution in the field of Variational Analysis.

17- Special issue of Mathematical Programming B on Optimization Models and Algorithms for Data Science
(source : M. Théra)

Dear Colleagues

We would like to draw your attention to an upcoming special issue of Mathematical Programming B on Optimization Models and Algorithms for Data Science.

Data and decisions are more strongly linked in the information age than ever before. This special issue focuses on modelling and optimization approaches that deal with large data sets, as well as applications from business analytics and machine learning that have emerged in the last decades as data accumulates from multiple sources such as internet traffic, social and sensor networks.

Successful submissions to this call are expected to provide a substantial methodological contribution to
- data-related modelling issues in optimization, such as tractable reformulations of problems involving uncertain data (e.g. using stochastic, robust or data-driven optimization techniques); or
- numerical solution schemes for optimization problems involving large data sets, such as solution approaches for large, sparse optimization problems or real-time optimization methods.

This call is being advertised via the British-French-German Conference on Optimization 2015 (optimisation.doc.ic.ac.uk/bfg2015). Attendance at the conference is not a pre-requisite for submitting a paper to the special issue, however.

Authors should submit their papers via http://www.editorialmanager.com/mapr/ and select article type "S.I.: Data Science — Series B" for consideration in this special issue.

Papers will be refereed according to the standards of Mathematical Programming, Series A. We are requesting that all papers be submitted using MP style files, and conform to a maximum of 25 pages. The necessary LaTeX files can be downloaded at www.eng.cam.ac.uk/~dr241/MPB/MPB- Springer-latex-style-files.zip.

Deadline for submission of full papers: December 1, 2015. We aim at completing a first review of all submissions by May 15, 2016.
