关于错排数的输出程序的研究

Study on Output Program Algorithm for Wrong Permutation Numbers

错排数在排列计数中有非常重要的作用,对于错排数的研究通常是利用递推关系。本文讨论一个更高效的错排数的输出算法。

Wrong permutation number is very important in permutation statistics. Some studies on it were generally made by recursive relation algorithm. In this paper, a more efficient algorithm is given.
