The EURO Working Group on Operational Research Applied to Health Services (ORAHS) was formed in 1975 as part of a program for developing special interest groups within the European branch, EURO, of the International Federation of Operational Research Societies, IFORS. The group currently has 242 members from 30 countries, mainly from Europe but also from overseas (e.g., USA, Canada, and Brazil). The group meets for a week each summer in a different, mainly European, host country. Meetings are open to anyone with a quantitative background and/or an interest in the subject area. However, the number of participants can be limited to ensure that an open debate is possible. The objectives of the group are to impart ideas, knowledge and experience on the application of OR approaches and methods to problems in the health services area, mutual support of members, co-operation on joint projects and stimulation of approaches and attitudes in the field of applied Operational Research (

04 Nov 2019 08 Nov 2019 Fields Institute, Stewart Library, Toronto Canada Winter School on Computational Data Science and Optimization

Toggle description

Data-driven analytics methodologies are presently at the forefront of efficient decision making and decision support in many industries. One prominent set of examples of this state-of-the-art computational data science and optimization tools that made headway is optimizing energy generation, storage, transmission and delivery, and trading. In a sense, nowadays, the employment of computational data science methodologies form a necessary condition for such systems to remain sustainable in the long-run and thrive, as we make a global transition to knowledge-and- information-based economy. These applications spread from operational to strategic time horizons. To name a few, optimization combined with machine-learning methods is successfully used to improve the efficiency SAGD process in oil recovery; optimization models and methods play a key role in determining efficient energy storage and dispatch strategies for smart grids, as well as help determine effective layouts for wind and solar farms; quantitative modelling and optimization occupy a central role when trading (energy) financial derivatives. However, despite these recent advances there is still a large gap between the most recent and vastly superior analytical tools available, and their practical applications.

The focus of the winter school is to train a new batch of highly qualified personnel that are essential in bridging the existing industry-to-academia gap. In addition, bringing together optimization thinking with more traditional data science approaches will help generate ideas for new approaches or improvements in existing approaches.

Scientific coordinators of INFRATRAIN are Prof. Dr. Christian von Hirschhausen (TU Berlin/DIW Berlin), Jens Weibezahn (TU Berlin), and Nicole Wägner (DIW Berlin)

07 Oct 2019 10 Oct 2019 Kiel Germany Simulation Modelling for Business Research

Toggle description

Abstract and Learning Objectives
Business research increasingly considers wicked problems and complex dynamic systems. Analytical models of such problems and systems quickly become untraceable and unsolvable. Given increasing computational power, simulation models provide an alternative tool. They can fuel studies tracing the long-term evolution of systems and comparing the outcomes of alternative scenarios. However, successfully applying simulation modelling for business research requires expertise on applicable simulation paradigms, approaches to model validation and the analysis of stochastic results.

30 Sep 2019 04 Oct 2019 Freie Universität Berlin, Berlin Germany Thematic Einstein Semester on Algebraic Geometry Varieties, Polyhedra, Computation

Toggle description

Fall School
This is the webpage of the fall school of the thematic Einstein semester Algebraic Geometry, which is devoted to the study of algebraic geometry and of its applications and is organised by Peter Bürgisser (TU Berlin), Gavril Farkas (HU Berlin) and Christian Haase (FU Berlin).

Times and Venue
The school will take place from the 30th of September 2019 to the 4th of October 2019 at Arnimallee 3 (Room SR 019 and SR 024) in the campus of the Freie Universität Berlin.

Greg Blekherman (Georgia Tech) - Convex and Algebraic Geometry of Sums of Squares on Varieties
A polynomial with real coefficients is called nonnegative if it takes only nonnegative values. For example, any sum of squares of polynomials is obviously nonnegative. The study of the relationship between nonnegative polynomials and sums of squares is a classical area in real algebraic geometry. The minicourse will be about the convex cones of nonnegative polynomials and sums of squares on a variety. Convex-geometric considerations, such as duality and facial structure of these cones will lead to new insights in algebraic geometry. The main questions we will consider are: when are all nonnegative polynomials sums of squares, and the number of squares needed to write a sum of squares.
Dawei Chen (Boston College) - Moduli of differentials and Teichmüller dynamics
An abelian differential defines a flat metric with conical singularities such that the underlying Riemann surface can be realized as a polygon with edges pairwise identified via translation. Varying the shape of such polygons induces a GL(2,R)-action on the moduli space of abelian differentials, called Teichmüller dynamics, whose study has provided fascinating results in many fields. I will give an introduction to this beautiful subject, with a focus on a combination of algebraic, analytic, combinatorial and dynamical viewpoints as well as some recent developments.
Giorgio Ottaviani (University of Florence) - Tensor Rank and Complexity
The asymptotic complexity of the matrix multiplication algorithm is one of the basic open problems in Complexity Theory. In other words, how many operations are needed to multiply two nxn matrices when n is large? The seminal work by Strassen and Bini translated this problem into the computation of the rank and the border rank of certain tensors, which can be studied with tools from Algebraic Geometry, especially in the symmetric case. The symmetric rank of a monomial can be computed by algebraic tools, and already this elementary case is not trivial. In the lectures we will review some important constructions and results in this area, and we will introduce the asymptotic rank, which in turn has a distinguished role in quantum computation. We will expose the recent computation of the symmetric border rank of a monomial by Christandl, Gesmundo and Oneto, by a clever use of the asymptotic rank.
Bernd Sturmfels (MPI Leipzig/Berkeley) - D-Modules and Holonomic Functions
In algebraic geometry we study the solutions of polynomial equations. This is equivalent to studying solutions of linear partial differential equations with constant coefficients. In these lectures we explore the more general case of partial differential equations whose coeffients are polynomials. The letter D stands for the Weyl algebra, and a D-module is simply a left module over D. We focus on left ideals, or D-ideals. These are the systems of linear PDE whose solutions we care about.
Functions in several variables can be modeled by the PDE they satisfy. A comprehensive class of functions with excellent algebraic properties are the holonomic functions. They are encoded by holonomic D-modules. These are useful for many applications, e.g. in geometry, physics and statistics. Course participants will learn how to work with holonomic functions.

Participants must apply at this link. We are working to acquire funding to offer support for travel or accommodation to some participants. The registration will close on the 1st of September 2019.
Due to space limitations and the overwhelming interest in our Fall School we might not be able to accommodate everybody who registered; we reserve the right to reject applications. We will send out notifications in early September.

For any question about this event, you may contact the email address or one of the organisers of the fall school: Daniele Agostini (HU Berlin), Thomas Krämer (HU Berlin), Marta Panizzut (TU Berlin), Rainer Sinn (FU Berlin).

Data science and optimisation are closely related. On the one hand, many problems in data science can be solved using optimisers, on the other hand optimisation problems stated through classical models such as those from mathematical programming cannot be considered independent of historical data. Examples are ample. Machine learning often relies on optimisation techniques such as linear or integer programming. Algorithms may be complete, approximative or heuristic and may be applied in on-line or off line settings. Reasoning systems have been applied to constrained pattern and sequence mining tasks. A parallel development of metaheuristic approaches has taken place in the domains of data mining and machine learning. In the last decades, methods aimed at high level combinatorial optimisation have been shown to strongly profit from configuration and tuning tools building on historical data. Algorithm selection has since the seventies of the previous century been considered as a tool to select the most appropriate algorithm for a given instance. Empirical model learning uses machine learning models to approximate the behaviour of a system, and such empirical models can be embedded into an optimisation model for efficiently finding an optimal system configuration.

The aim of the workshop is to organize an open discussion and exchange of ideas by researchers from Data Science and Operations Research domains in order to identify how techniques from these two fields can benefit each other. The program committee invites submissions that include but are not limited to the following topics:
- Applying data science and machine learning methods to solve combinatorial optimisation problems, such as algorithm selection based on historical data, speeding up (or driving) the search process using machine learning, and handling uncertainties of prediction models for decision-making.
- Using optimisation algorithms in developing machine learning models: formulating the problem of learning predictive models as MIP, constraint programming (CP), or satisfiability (SAT). Tuning machine learning models using search algorithms and meta-heuristics. Learning in the presence of constraints.
- Embedding methods: combining machine learning with combinatorial optimization, model transformations and solver selection, reasoning over Machine Learning models.
- Formal analysis of Machine Learning models via optimization or constraint satisfaction techniques: safety checking and verification via SMT or MIP, generation of adversarial examples via similar combinatorial techniques.
- Computing explanations for ML model via techniques developed for optimization or constraint reasoning systems
- Applications of integration of techniques of data science and optimization.


We invite the following submissions (all in the IJCAI proceedings format, see: ):
- Submission of original work up to 8 pages in length.
- Submission of work in progress (with preliminary results) and position papers, up to 6 pages in length.
- Published journal/conference papers in the form of a 2-pages abstract.
The program committee will select the papers to be presented at the workshop according to their suitability to the aims.
Contributors of the workshop will be invited to submit full versions of their papers for inclusion in a special volume of the Annals of Mathematics and Artificial Intelligence, published by Springer.
Those invited submissions will be subject to refereeing at the usual standards of the journal, and authors will receive more details with the acceptance notice.

15 Jul 2019 19 Jul 2019 Certosa di Pontignano (Siena – Tuscany) Italia 2nd Advanced Course on Data Science & Machine Learning (ACDL)

Toggle description

The 2nd Advanced Course on Data Science & Machine Learning (ACDL) is a full-immersion five-day residential Course at the Certosa di Pontignano (Siena – Tuscany, Italy) on cutting-edge advances in Data Science and Machine Learning with lectures delivered by world-renowned experts. The Course provides a stimulating environment for academics, early career researches, Post-Docs, PhD students and industry leaders. Participants will also have the chance to present their results with oral talks or posters, and to interact with their peers, in a friendly and constructive environment.
You will gain a heightened awareness for fields of data science and machine learning relevant for your activity and, perhaps most important, you will gain a place within an elite global network of data scientists and machine learning experts.
The Advanced Course is not a summer school suited only for younger scholars. Rather, a significant proportion of seasoned investigators are regularly present among the attendees, often senior faculty at their own institutions. The balanced audience that we strive to maintain in each Advanced Course greatly contributes to the development of intense cross-disciplinary debates among faculty and participants that typically address the most advanced and emerging areas of each topic.
Each faculty member presents lectures and discusses with the participants for one entire day. Such long interaction together with the small, exclusive Course size provides the uncommon opportunity to fully explore the expertise of each faculty, often through one-to-one mentoring. This is unparalleled and priceless.
The Course will involve a total of 36-40 hours of lectures, according to the academic system the final achievement will be equivalent to 8 ECTS points for the PhD Students and the Master Students attending the summer school.
The Certosa di Pontignano provides the perfect setting to a relaxed yet intense learning atmosphere, with the stunning backdrop of the Tuscan landscapes. World-class wines and traditional foods will make the Advanced Course on Data Science & Machine Learning the experience of a lifetime.

07 Jul 2019 13 Jul 2019 Instituto de Matemáticas de la Universidad de Sevilla, IMUS, Seville Spain ECMI Postgraduate / VI Iberian / NeEDS Modelling Week

Toggle description

The ECMI Postgraduate / VI Iberian / NeEDS Modelling Week will be held at the Mathematical Institute of the University of Seville (Seville, Spain) on July 7th-13th, 2019. It is co-organized by the European Consortium for Mathematics and Industry (, the Spanish Network for Mathematics-Industry (, the Portuguese Network of Mathematics for Industry and Innovation (, and the H2020-MSCA-RISE NeEDS project (, and takes part of the satellite meetings to the 9th International Congress on Industrial and Applied Mathematics (July 15th-19th, 2019, Valencia, Spain).

The format of the Modelling Week is to spend one week working to solve real problems that can be tackled through mathematical modeling. Small groups of multinational Master students, Ph.D. students and junior researchers (like post-doctoral students) will be assigned to each problem in term of their preference and own skills on the first day of the event after the presentation of the problems. An instructor, that must be an expert in the area, of the proposed problem leads each of these groups. During the following four days students will work on solving the problems under the guidance of the instructor and industrial collaborators. Last day of the meeting will be devoted to the presentation of the results, which will be collected in the proceedings of the event.
