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.

Following the decision of the programme committee of ICALP 2009 Track B, Dominik Wojtczak (a former PhD student at University of Edinburgh, currently a postdoc at CWI) together with Michael Ummels (PhD student at RWTH Aachen) has won the Best Student ICALP Paper award of Track B for their paper titled: "The Complexity of Nash Equilibria in Simple Stochastic Multiplayer Games".

Mathematics makes wireless networks more efficient

How many cellphone masts should be placed in order to reach everyone? If there are ten additional stations eligible for grants, where can these be placed best? PhD student Erik Jan van Leeuwen of the Centrum Wiskunde & Informatica(CWI) in Amsterdam described the problems with geometric models.

Innovative CWI research wins Free Competition

Two CWI research proposals have received money in the Free Competition 2008 of the Netherlands Organisation for Scientific Research (NWO) division for Exact Sciences. From 58 entries the research of Bert Gerards into matrices and Marie-Collette van Lieshout’s research into Markov polygonal fields were selected among 13 proposals. Three million euros will be divided between them. In total five mathematics proposals were awarded.
