Abstract: A procedure for defining the constraints and limits for approximating a non-linear function by piecewise polynomial functions is presented. We consider the free variable to be generated with ...

In this paper, we propose a method for finding the best piecewise linearization of nonlinear functions. For this aim, we try to obtain the best approximation of a nonlinear function as a piecewise ...

Abstract: This paper proposes a method for calculating the economic generation dispatch for generating units with a piecewise linear incremental cost function, at the same time considering total power ...

Suppose that ƒ(x) = 2√x - 1. The formula in terms of x for each of the functions is: The graph was shifted to the right 1 unit, and stretched vertically by a factor of 2. Suppose we were given the ...
