The value function of an optimization problem gives the value attained by the objective function at a solution, while only depending on the parameters...

Function value may refer to: In mathematics, the value of a function when applied to an argument. In computer science, a closure. This disambiguation page...

a multivalued function, multiple-valued function, many-valued function, or multifunction, is a function that has two or more values in its range for...

the absolute value function is idempotent (meaning that the absolute value of any absolute value is itself). The absolute value function of a real number...

In mathematics, a real-valued function is a function whose values are real numbers. In other words, it is a function that assigns a real number to each...

A set-valued function, also called a correspondence or set-valued relation, is a mathematical function that maps elements from one set, the domain of the...

A vector-valued function, also referred to as a vector function, is a mathematical function of one or more variables whose range is a set of multidimensional...

possible applications of the concept. A function is often denoted by a letter such as f, g or h. The value of a function f at an element x of its domain (that...

a continuous function is a function such that a small variation of the argument induces a small variation of the value of the function. This implies...

complex-valued function f on an arbitrary set X (is isomorphic to, and therefore, in that sense, it) can be considered as an ordered pair of two real-valued functions:...
