WebMay 17, 2024 · Abstract. In this book, we discuss various root finding algorithms, such as bisection method, regula-falsi method, Newton-Rapson method, Halley's method, Steffensen's method and a hybrid root ... WebThe root finding algorithms described in this section make use of both the function and its derivative. They require an initial guess for the location of the root, but there is no absolute guarantee of convergence—the function must be suitable for this technique and the initial guess must be sufficiently close to the root for it to work.
