So, you explicitly *don't* want a random selection? By "spatially
distributed" you mean that if you have already chosen one
particular location, other locations which are close to it should
be less probable (or impossible) to include in the limited result
set? How would you define the desired result? The one with the
highest best solution to the "traveling salesman" problem?
