三维线性规划的随机边规则

The Random Edge Rule on Three-Dimensional Linear Programs

Volker Kaibel, Raphael Mechtel, Micha Sharir, Günter M. Ziegler

摘要:

对于n个约束的三维线性规划,采用随机边主元规则的单纯形算法所取路径的最坏情况期望长度f(n),当n足够大时,有界为1.3445 n ≤ f(n)≤ 1.4943 n.

英文摘要:

The worst-case expected length f(n) of the path taken by the simplex algorithm with the Random Edge pivot rule on a 3-dimensional linear program with n constraints is shown to be bounded by 1.3445 n <= f(n) <= 1.4943 n for large enough n.
