If f is di erentiable and coercive. Then the global minimum of f is the stationary point of fwith the least objective function value. Proof. If f is di erentiable and coercive, then there is at least one global minimum. After all, if f does not have a global minimum, then it must take arbitrary large negative values.

"WebA schematic illustration of a bounded function (red) and an unbounded one (blue). Intuitively, the graph of a bounded function stays within a horizontal band, while the graph of an unbounded function does not. In mathematics, a function f defined on some set X with real or complex values is called bounded if the set of its values is bounded. " - F is coercive
