Convex … 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 … See more A set of points in a Euclidean space is defined to be convex if it contains the line segments connecting each pair of its points. The convex hull of a given set $${\displaystyle X}$$ may be defined as 1. The … See more In computational geometry, a number of algorithms are known for computing the convex hull for a finite set of points and for other geometric objects. Computing the convex hull means … See more Convex hulls have wide applications in many fields. Within mathematics, convex hulls are used to study polynomials, matrix eigenvalues, and unitary elements, and several theorems in discrete geometry involve convex hulls. They are used in robust statistics as … See more Closed and open hulls The closed convex hull of a set is the closure of the convex hull, and the open convex hull is the interior (or in some sources the See more Finite point sets The convex hull of a finite point set $${\displaystyle S\subset \mathbb {R} ^{d}}$$ forms a convex polygon when According to the See more Several other shapes can be defined from a set of points in a similar way to the convex hull, as the minimal superset with some property, the … See more The lower convex hull of points in the plane appears, in the form of a Newton polygon, in a letter from Isaac Newton to Henry Oldenburg in 1676.
