WebFirst, the convex hull of Gis known to be a polytope in R. n+1. having 2. n. extreme points (x;y) that correspond in a one-to-one manner with the extreme points of Xso that the values of xare preserved and so that y= m(x): Second, the convex hull representation of (1.1) depends upon the speci c bounds land ufound in In geometry, the convex hull or convex envelope or convex closure of a shape is the smallest convex set that contains it. The convex hull may be defined either as the intersection of all convex sets containing a given subset of a Euclidean space, or equivalently as the set of all convex combinations of points in the subset. For a bounded subset of the plane, the convex hull may be visualized a… charles schmid and mary french
