Kort presentation
I am a researcher in the Optimisation group: we address the solution of optimisation problems — such as scheduling, personnel allocation, and vehicle routing — via basic, strategic, and applied research. These problems are akin to complex puzzles, where decisions have to be made so that some constraints are satisfied. Often, some cost must be minimised.
See my researcher homepage for more information.
