| Abstract: | In this paper,two algorithms for computing the high order derivative of PageRank are presented.Furthermore,some mathematical properties of the coefficient matrix involved are discussed,and the advantages and disadvantages of the two formulas for computing the high order derivative of PageRank are analyzed.Numerical results show the numerical behavior of the new algorithm. |
