THE COMPUTATIONAL EFFICIENCY AND THE OPTIMAL UPDATE PERIOD OF THE ENTRY-UPDATE NEWTON-LIKE METHOD
换元Newton型方法的计算效能和最佳换元周期

In this paper, the computational efficiency of the entry-update Newton-like method forsolving systems of n nonlinear equations is considered. By studying the efficiency index, theoptimal update period of this method is given and is proved to be independent of n in somesense.
