In [[numerical analysis]], the '''Weierstrass method''' or '''Durand–Kerner method''', discovered by [[Karl Weierstrass]] in 1891 and rediscovered independently by Durand in 1960 and Kerner in 1966, is a [[root-finding algorithm]] for solving [[polynomial]] [[equation (mathematics)|equations]].<ref name="Petković">{{cite book |last1=Petković |first1=Miodrag |title=Iterative methods for simultaneous inclusion of polynomial zeros |date=1989 |publisher=Springer |___location=Berlin [u.a.] |isbn=978-3-540-51485-5 |pages=31–32}}</ref> In other words, the method can be used to solve numerically the equation
