Zusammenfassung:We present in this paper an algorithm for solving nonlinear equation systems that is a modification of Powell's dogleg method. The modifications are designed to make the technique more efficient and reliable and to reduce storage requirements. The performance of the new algorithm on a set of standard test problems demonstrates its effectiveness.
