[D] Simple Questions Thread September 27, 2020

I have a large data set of images with associated spatial coordinates. This data set represents a large raster scan (in the spatial coordinate space.) I do have a simple cost function that takes these images and returns a single, positive real number. Let's call a spatial position x, and the real scalar F(x). If I were to consider **only** the spatial coordinates and these responses, I have a fairly straightforward optimization problem.
