We invite PhD students to a Nordic winter school on Advanced Stochastic Optimization at the Norwegian Univer- sity of Science and Technology (NTNU) in Trondheim, Norway, from 1 – 5 December 2025. The course is part of the Nordic Courses in Stochastic Programming, a cooperation between NTNU, NHH in Bergen, and UCPH in Copenhagen that provides PhD courses on stochastic programming. The course builds on the material taught in the introduction-level Nordic PhD course in stochastic programming taught in Bergen in September this year. Prior participation in that course is not mandatory, but some basic knowledge of stochastic pro- gramming models is required. The course is taught by multiple lecturers, each teaching on their field of expertise. This provides PhD students a unique opportunity to learn from and connect with experts in the field, as well as with other students with similar interests. The following lecturers will give talks on the indicated topics: Vincent Leclère (Ecole des Ponts, Paris) – Stochastic dual dynamic programming and related methods Francesca Maggioni (University of Bergamo) – Bounding techniques in (multi-stage/-horizon) stoch. programs Ward Romeijnders (University of Groningen) – Mixed-integer stochastic programming Peter Schütz (NTNU) – Dual decomposition Stein-Erik Fleten (NTNU) – Applications in energy systems Ruben van Beesten (Erasmus University Rotterdam, NTNU) – Quick recap of basics, modeling risk aversion The course takes place at the Gløshaugen campus in Trondheim from 1 – 5 December. During this week, the tra- ditional Christmas market on the city square starts, which will keep you busy during the evenings. Lectures start Monday morning and end around 14:00 on Friday. Participation is free of charge. Students that wish to receive credits (5 EC) should write a 10-page essay after the course related to one of the topics discussed (you can relate this to your own research project), graded pass/fail. The deadline for registration is 15 September (if you cannot make the deadline, email me to ask for remaining options). See the second page of this document for instructions on how to register. For any remaining questions, contact me using the email address below. I hope to see many of you there!
