METHOD OF QUADRATIC INTERPOLATION KELLER VANDEBOGERT 1. Introduction Interpolation methods are a common approach to the more general area of line search for optimization. In the case of quadratic inter-polation, the function’s critical value is bracketed, and a quadratic interpolant is tted to the arc contained in the interval. Then, the

Quadratic Interpolation. The method known as quadratic interpolation was first proposed by Powell [3] and uses the values of the function f to be minimized at three points to fit a parabola p(α) = a+bα +cα2, (4.1.3) through those points. The method starts with an initial point, say, α = 0 with a function value p 0 = f(x 0), and a step ...
