Christoph, I do see your point regarding lacking information in papers. Truth to be told, most labelling research is from computational geometry and they do often not care too much about actually labelling the maps, weird as it sounds. And as a more math-based discipline, they have a very

Serge, I greatly appreciate your input from other disciplines. As to the cultural differences between fields, I was never implying the structure of either is better than the other. As much as I can see why providing the full implementation is the true proof of the pudding for some fields, in

That's really a pitty. How can someone profit from your work (aka Shoulders of Giants)? What worth is it pointing to us, how bad our label placement is and how good it could be by not giving us the tools to fix it? I did not want to abuse anybody. At frist I tried to present the results that
