A = (C/1) * 0.85 + 0.15 = 0.85C + 0.15_____(1)B = (A/2) * 0.85 + 0.15 = 0.425A + 0.15 _____(2)C = (A/2+B/1) * 0.85 + 0.15 = 0.425A + 0.85B + 0.15 _____(3)

整理(2)(3) 可知 1.85B = C代入 (1) 得 A = 1.5725B + 0.15 ____(4)

將 (2) 代入 (4) 中得 A = 1.5725(0.425A + 0.15) + 0.15 所以A = 1.163

     B = 0.425 * 1.163 + 0.15 = 0.644     C = 0.425 * 1.163 + 0.85 * 0.644 + 0.15 = 1.19

所以PageRank為 : C > A > B
