An important method of constructing a convex set from an arbitrary set of points is that of taking their convex hull (see fig todo) formally, if x:= fx i 2rn j1 i mgis an arbitrary set of points, then its convex hull is the set obtained by taking all possible convex. There's the convex hull for that set of it's the smallest convex set that contain all the points, the smallest area of convex polygon. The following statements are true about the convex minimization problem: if a local minimum exists, then it is a global minimum the set of all (global) minima is convex for each strictly convex function, if the function has a minimum, then the minimum is unique these results are used by the theory of convex minimization along with.

The link between convex sets and convex functions is via the epigraph: a function is convex if and only if its epigraph is a convex set any convex real function f(x) has unique minimum value over any convex subset of its domain yet solution to some convex optimization problem is, in general, not unique eg, given a minimization of a. What is the difference between convex and non-convex optimization problems how do we know whether a function is convex or not the points of a convex set can all be connected using line segments that do not leave the set.
