Webshowed that the problem of deciding whether two sets of points in general space can be separated by the intersection of two hyperplanes is NP-complete, and Khot and Saket [2011] showed that “unless NP = RP, it is hard to (even) weakly PAC-learn intersection of two halfspaces”, even when allowed the richer class of O(1) intersecting halfspaces. A convex polytope may be defined in a number of ways, depending on what is more suitable for the problem at hand. Grünbaum's definition is in terms of a convex set of points in space. Other important definitions are: as the intersection of half-spaces (half-space representation) and as the convex hull of a set of points (vertex representation). In his book Convex Polytopes, Grünbaum defines a convex polytope as a compact convex set wit…

WebThe convex hull of a set of points \(S\) is the intersection of all half-spaces that contain \(S\). A half space in two dimensions is the set of points on or to one side of a line. This notion generalizes to higher dimensions.
