On behalf of the Technical University of Denmark, the Danish Operations Research Society and the Nordic Section of the Mathematical Programming Society we welcome you to Copenhagen and the 1st Nordic Optimization Symposium - the 10th meeting of the Nordic MPS. The meetings of the Nordic MPS have evolved to be more that just a meeting on Mathematical Programming. They are a forum for discussing a wide range of related areas and practical cases. In the organizing committee we wanted the name of the meeting to reflect this. We have therefore in agreement with the board of the Nordic MPS suggested to add a new title, that reflects the much broader field that is our playground at these meetings. Still the odd trustworthy title “Meeting of the Nordic MPS” has been maintained to demonstrate the origin of the symposium. It is our hope that future Nordic MPS meetings will carry on using this “double name”. The program includes 2 plenary lectures by Leo Kroon and Arne Drud and more than 50 contributed presentations. The symposium has this time expanded beyond our Nordic boundaries with participants from eg. the Netherlands, Italy and New Zealand. As a consequence the original 2 parallel streams we had in mind have extended to 3 throughout the symposium. It is our firm belief that this symposium will - like all the previous Nordic MPS meetings - be a fruitfull ground for collaboration and networking and therebye further tighten the ties between the Nordic countries in relation to optimization, Operations Research and Mathematical Programming. Finally we would like to thank our sponsors and supporter for their contributions. It has among other things made it possible to give free registration to a number of researchers from the Baltic countries and Ph.D. students in general. We wish you all an enjoyable 1st Nordic Optimization Symposium (10th Nordic MPS meeting) in Copenhagen.
