Question for statisticians. I have process that obtains a specific property of a point in a two-dimensional space, if I calculated it in the whole plane it would give values as in the attached picture (not necessarily Gaussian, it is only illustrative). The thing is, I need to find the point where that property is greatest without having to calculate all of them. Is there an algorithm or numerical method to reduce the number of tests over the space and quickly find the hot spot?
