public class KrigSamplingGenerator extends com.opttek.optquest.SolutionGenerator
This is the simplest version of using Kriging to generate simulation locations. It assumes that you're mapping a lat/lon pair and the locations are chosen in the areas that have the maximum interpolated variance. Note: this will get very slow, there's a hidden O(N^2) algorithm here - as we add more points the interpolation becomes slower. For the use cases we have, it's ok. We have 7 hours to pick a point, so I'm not worried But we still should look at restructuring this to not redo a lot of computation that we don't have to do.
