👉 In mathematics, a bound is a limit or an upper or lower bound of some set. It is a numerical value that represents a maximum or minimum value and can be used to determine if a set is contained within another set. Boundaries are often used in optimization problems where one wants to find the best solution for maximizing or minimizing some function, such as the area under a curve, or the distance between two points on a line. For example, in optimization problems, we may want to find the
