I'm a Master student at the University of Leuven, Belgium. I have to make a report of a case concerning the 'Price-Collecting Steiner Tree'. We have our model and our restrictions. We are just looking for a program to run it and to find the optimal solution. So far we have only found one but the problem is that it runs only on Linux, and nor I, nor my teammates, have knowledge about how Linux operates. Does anyone know some software which runs on Windows or does anyone has some other useful information for me?
