Dutch Seminar on Optimization

Welcome to the website of the Dutch Seminar on Optimization.


The Dutch Seminar on Optimization is an initiative to bring together researchers from the Netherlands and beyond. The objective is to establish a new forum for the Dutch optimization community to come together, to help provide a spotlight for up and coming local talent, and to bring in high quality international speakers. 

The topics of the seminar are centered around Optimization in a broad sense, but with a focus on (though not limited to) the theoretical foundations of discrete and continuous optimization. We would like to invite all researchers, especially also PhD students, who are working on related topics to join the events. 

The next talks of the seminar will be given on Thursday, December 9, 2021, 16:00 by Hadi Abbaszadehpeivasti (Tilburg University) and Utku Karaca (Erasmus University); see the events section for more details.

If you want to be subscribed to the mailing list of the seminar to receive regular announcements, please contact Sven Polak (sven.polak@cwi.nl)


The seminar will be organized online (for now) and take place once a month. The default policy is to have the seminar on Thursday of the last week of the month. The talks will be announced through this website and by email using the seminar's mailing list. 

The video recordings and pdfs of the slides of the lectures can be found in the events section (links below).

The kick-off of the seminar took place on Wednesday, December 16, 2020, 16:00, with a lecture by Laura Sanita (TU Eindhoven).


This seminar series is initiated by the CWI Networks and Optimization group (Nikhil Bansal, Daniel Dadush, Monique Laurent, Guido Schäfer), jointly with other Dutch research groups in Optimization.

There is an organization committee in place that is in charge of reaching out to speakers. The committee consists of the following members: Jesper Nederlof (Utrecht University), Daniel Dadush (CWI), Steven Kelk (Maastricht University), Etienne de Klerk (Tilburg University), Fernando Oliveira (TU Delft), Juan Peypouquet (RU Groningen), Rene Sitters (VU Amsterdam), Frits Spieksma (TU Eindhoven), Leen Stougie (CWI), Marc Uetz (University of Twente), Tjark Vredeveld (Maastricht University).


If you have any suggestions for speakers (or want to give a talk yourself), please feel free to contact any of the committee members. If you have any general suggestions or questions related to the seminar, please get in touch with Daniel Dadush (dadush@cwi.nl).
