In mathematics, the arguments of the maxima (abbreviated arg max or argmax) are the points, or elements, of the domain of some function at which the function values are maximized. In contrast to global maxima, which refers to the largest outputs of a function, arg max refers to the inputs, or arguments, at which the function outputs are as large as possible. WebThis function has a single minimum, f(2) = 3. The minimum is 3, while the argmin is x = 2, the value of the decision variable at which the minimum occurs.
