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 talk will be given by Steven Miltenburg and Antonina Khramova on Thursday, 5 December 2024.
If you want to be subscribed to the mailing list of the seminar to receive regular announcements, please contact Cedric Koh (Zhuan.Koh@cwi.nl).
Dutch Day on Optimization
The 3rd Dutch Day on Optimization took place at the University of Twente on 7 November 2024; see this webpage for details. It is the yearly in-person event related to the Dutch Seminar on Optimization. The main purpose of the event is to bring together the Dutch optimization community across the areas of operations research, computer science and discrete mathematics. The event highlights the research of both national and international speakers. Previous versions were held in Maastricht University and Amsterdam Science Park Congress Center.
Dutch Intercity Optimization Seminar
The 2nd Dutch Intercity Optimization Seminar took place at VU Amsterdam on 23 May 2024; see this webpage for details. Together with the Dutch Day on Optimization, the intercity seminars are our in-person events, which will rotate between participating institutions. The 1st version was held at CWI.
Schedule
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).
