Some definitions of convex function and concave function in domestic and abroad are opposite convex function and concave function_ convex functions

Convex Function A convex function is a continuous function whose value at the midpoint of every interval in its domain does not exceed the Arithmetic mean of its values at the ends of the interval. More generally, a function was convex on a interval if to any two points and where, (Rudin 1976, p. Cf. Gradshteyn and Ryzhik, p. 1132). If has a second derivative in,

Convex Hull (convex hull)

Given a (finite) Point Set (a group of points) on a plane, the convex hull of this point set is a convex polygon that contains the minimum area of all points in the point set. In a two-dimensional Euclidean space, a convex bag can be imagined as a rubber circle containing just all vertices. This can be vividly thought like this: place some unmovable wooden piles
