DurandKerner method's wiki: In numerical analysis, the DurandKerner method, discovered by Karl Weierstrass in 1891 and rediscovered independently by Durand in 1960 and Kerner in 1966, is a rootfinding algorithm for solving polynomial equations.As one can see above, there are three roots. Let's try to apply the DurandKerner scheme described on Wikipedia. Basically, at each step we move a little from the previous estimate. If this sort of equation looks familiar to you, it's because it is Newton's root finding method for polynoms (where the derivate can be computed exactly)! durand kerner method example

The DurandKerner method solves almost all n th degree equations (in the sense of Lebesgue), but it makes no sense to ask for worst case behaviour. Note that the root operations required in the classical formulas for equations of low degree, (2, 3, 4, not 5), are not easier than the general case. durandkerner Finds all the roots of a polynomial by Weierstrass' method (or known in Abramowitz& Stegun as the DurandKerner method). This is basically a generalization of Newton's method that works for multiple roots.**durand kerner method example** And I had done some research in the Internet and found DurandKerner Method itself is unstable. It does not always converge. I do not know if there is a known way to force the algorithm towards convergence if it diverges.
