【Abstract】 In this paper, we prove the convergence of two Levenberg-Marquardt type nonli-near least squares algorithms. One was improved by Fletcher and the other was amodification to Meyer’s algorithm. In contrast to [6], the boundedness of dampingfactor series becomes a conclusion here instead of an assumption.更多还原
