Abstract
Several one-parameter families of fourth-order methods for finding multiple zeros of non-linear functions are developed. The methods are based on Murakami's fifth-order method (for simple roots) and they require one evaluation of the function and three evaluations of the derivative. The informational efficiency of the methods is the same as the previously developed methods oflov.1er order. For a double root, the method is more efficient than all previously known schemes. All these methods require the knowledge ofmultiplicity.
