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.

Floor Sietsma awarded 'Nerd van het Jaar 2012'

Researcher at the Centrum Wiskunde & Informatica (CWI) in Amsterdam Floor Sietsma is awarded by Quest readers as Nerd of the Year 2012. In the race she left her main competitors Diederik Jekel, known from ‘De Wereld Draait Door’ and medical biologist Elza van Deel behind, who finished in second and third place.

Improved lower bounds for chromatic number

Researcher Fernando de Oliveira Filho of the Centrum Wiskunde & Informatica (CWI) in Amsterdam improved the lower bounds on the chromatic number. He received his PhD degree on December 1 for his thesis 'New Bounds for Geometric Packing and Coloring via Harmonic Analysis and Optimization'.

D. Wojtczak receives Best paper award at ICALP 2009

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.
