Demo . Newton-Raphson •Best-known algorithm for getting quadratic convergence when derivative is easy to evaluate WebBrent's method [ Br02] is effectively a safeguarded secant method that always keeps a point where the function is positive and one where it is negative, so that the root is always bracketed. At any given step, a choice is made between an interpolated (secant) step and a bisection in such a way that eventual convergence is guaranteed.

In numerical analysis, Brent's method is a hybrid root-finding algorithm combining the bisection method, the secant method and inverse quadratic interpolation. It has the reliability of bisection but it can be as quick as some of the less-reliable methods. The algorithm tries to use the potentially fast … See more The idea to combine the bisection method with the secant method goes back to Dekker (1969). Suppose that we want to solve the equation f(x) = 0. As with the bisection method, we need to … See more Brent (1973) proposed a small modification to avoid the problem with Dekker's method. He inserts an additional test which must be satisfied before the result of the secant method is accepted as the next iterate.
