title: Determining the optimum points of two classes of two-band functions
abstract: The study tested thrice differentiable functions whose definitional domain can be divided into several intervals (zones) with significantly different rates of function growth. A strict definition of the optimum point through the curvature of the curve is given. For two classes of convex two-band functions the problem of finding the optimum point is solved in a general way.
