In convex geometry, a convex set is a subset of an affine space that is closed under convex combinations more specifically, in a euclidean space,. Now, the x coordinates of any point in the interior of the convex set can be expressed as the weighted average of some points on the boundary.

Convex functions convex optimization problems duality approximation and fitting statistical estimation geometric problems numerical linear algebra background. This book is about convex optimization, convex geometry if c is a closed convex set, unique projection px of a point x on convex set c. The convex hull of a finite point set is the set of all convex combinations of its points in a convex combination, each point in is assigned a weight or coefficient in such a way that the coefficients are all non-negative and sum to one, and these weights are used to compute a weighted average of the points.

Lecture 2 outline • review basic topology in rn • open set and interior • closed set and closure • dual cone • convex set • cones • affine sets . The convex hull, also known as the convex envelope, of a set x is the smallest convex set of which x is a subset formally, definition: the convex hull h(x) of a set x is the intersection of all convex sets of which x is a subset if x is convex, then obviously h(x) = x, since x is a subset of.
