TL;DR: The top-down sampling method is introduced that allows to model non-stationary and continuous (but not differentiable) spatial variations of uncertainty sources by creating nested random fields (RFs) where the hyperparameters of an ensemble of RFs is characterized by yet another RF.

Finding the convex hull of a simple polygon
TL;DR: An earlier convex hull finder of the authors' is limited to polygons which remain simple when locally non-convex vertices are removed, so this paper amended its earlier algorithm so that it finds with complexity O(m) the convex Hull of any simple polygon, while retaining much of the simplicity of the earlier algorithm.
