CWI researcher Monique Laurent elected as KNAW member

Researcher and MT member Monique Laurent from Centrum Wiskunde & Informatica (CWI) was elected as a member of the Royal Netherlands Academy of Arts and Sciences (KNAW). The KNAW announced this on 19 April 2018. KNAW members are prominent scientists who are nominated by fellow researchers within and outside the Academy.

CWI and ProRail predict railway incidents

Centrum Wiskunde & Informatica and ProRail recently started a research collaboration in the area of the handling of incidents at the Dutch railways. It concerns a public private partnership between CWI and ProRail striking up a four year period. The research is aimed at prevention and handling of a broad spectrum of railway incidents, like disturbance of the railway infrastructure, people walking on the tracks and collisions.

Monique Laurent elected as Fellow of SIAM

CWI researcher Monique Laurent is elected as a Fellow of the international Society for Industrial and Applied Mathematics – SIAM. This prestigious Fellowship honours SIAM members who have made outstanding contributions to these fields. Laurent, who is a member of the management team of CWI and a professor at Tilburg University, receives the fellowship for her contributions to discrete and polynomial optimization and revealing interactions between them.

Rubicon grants for David de Laat and Alessandro Zocca

CWI researchers David de Laat and Alessandro Zocca both received an NWO Rubicon grant. De Laat will study new techniques to compute optimal packings at MIT for one year, and Zocca will study renewables and uncertainty in future power systems at Caltech for two years. NWO granted these subsidies to 22 young, highly promising research talents to gain international research experience at foreign top institutes.

Veni grants for Daniel Dadush and Hannes Mühleisen

The Netherlands Organisation for Scientific Research (NWO) has awarded Veni grants to Daniel Dadush and Hannes Mühleisen of CWI. The funding allows these researchers, who have recently obtained their PhD, to conduct independent research and develop their ideas for a period of three years.

Lex Schrijver receives EURO Gold Medal 2015

Researcher Lex Schrijver of CWI has been awarded the EURO Gold Medal 2015. This prize is considered the highest European distinction in Operational Research (OR) and is awarded by the Association of European Operational Research Societies (EURO).

Cooperative behaviour is not instinctive, but learnt

Cooperative behaviour is not an instinctive impulse or deliberate choice, but a learning process. Researchers of CWI and LUISS Guido Carli in Rome showed in an experiment that people living in a low-trust society intuitively choose non-cooperation in games. However, after playing several times their intuitive choices become more cooperative.

Invited lecture Monique Laurent at ICM 2014

Monique Laurent will give an invited lecture at the International Congress of Mathematicians (ICM) 2014 on Wednesday 20 August in Seoul, Korea. It is a great honour to speak at ICM, the most important conference for mathematicians in the world, with thousands of participants and the award of the Fields Medals.

Bert Gerards on Solving Rota’s Conjecture in AMS Notices

Bert Gerards (CWI), Jim Geelen (University of Waterloo, Canada) and Geoff Whittle (Victoria University of Wellington, New Zealand) have published an article on Solving Rota’s Conjecture in the August issue of AMS Notices. The authors recently announced that they solved Rota's Conjecture after 15 years of work.

Conditions for optimal solutions to semidefinite problems found

Most optimization problems in real-life are hard to solve optimally. However, for practical purposes it is usually sufficient to settle for near-optimal solutions that can be found quickly. Fast and more accurate approximations can be computed using semidefinite programming, a novel powerful optimization tool

MINO project on business decisions starts at CWI in October 2013

The Networks & Optimization research group at CWI in Amsterdam participates in the recently funded EU Initial Training Network MINO for Mixed Integer Nonlinear Optimization. It has eleven academic partners(such as CWI and project coordinator Bologna University) and three commercial partners (IBM, MAIOR and ORTEC).

CWI researcher proves famous Rota’s Conjecture

Mathematician Bert Gerards of Centrum Wiskunde & Informatica (CWI) in Amsterdam and his colleagues Jim Geelen (University of Waterloo, Canada) and Geoff Whittle (Victoria University of Wellington, New Zealand) have proved the famous 40-year old Rota’s Conjecture. The team has been working for more than 15 years on solving this mathematical problem posed by Gian-Carlo Rota in 1970.

Neil Olver receives Veni grant for network research

The Dutch Organization for Scientific Research (NWO) has awarded Neil Olver a Veni grant for his project 'Designing better, faster networks'. Olver, who is currently affiliated with the Mathematics department of MIT, will carry out his research at the Operations Research group at VU University Amsterdam and the Networks and Optimization group at Centrum Wiskunde & Informatica.

Lex Schrijver elected AMS Fellow

The American Mathematical Society (AMS) chose its first AMS Fellows, and among them is Lex Schrijver from the Centrum Wiskunde & Informatica (CWI) and the University of Amsterdam. Other Dutch members of the 2013 inaugural class are Frank den Hollander (Leiden University and CWI Governing Board), Robbert Dijkgraaf (Institute of Advanced Study and UvA), Jacob Korevaar (em.
