New Root-Seeking Algorithms

One is Brents's algorithm (inverse quardratic interpolation with bisection) and the other is the "Illinois" algorithm (which I heard of long before the published work.) There is another modification of Newton's method that raises its effective rate (to Sqrt(8)). The idea is to evaluate f(x) and f'(x) at different xs. (http://www.sciencedirect.com/science/art...30)There's also Chebychev's method which is (like Halley's) a Taylor series; Chebychev used the series and Halley used the continued fraction for the series. Also a guy named Galindo did rather well with bunches of tests and algorithms.

You link is confusing my browser! Can you please send a link that works. I would like to read the material you are pointing to.
