摘要

我们提出了两个简单、直观和通用的算法框架，可用于设计各种排列生成算法。这些框架可以用来产生19种现有的排列算法，包括著名的Heap、Wells、Langdon、Zaks、Tompkins和Lipski算法。我们使用这些框架设计了两种新的基于排序的排列生成算法，其中一种是最优的。

A Unified Framework to Discover Permutation Generation Algorithms

We present two simple, intuitive and general algorithmic frameworks that can be used to design a wide variety of permutation generation algorithms. The frameworks can be used to produce 19 existing permutation algorithms, including the well-known algorithms of Heap, Wells, Langdon, Zaks, Tompkins and Lipski. We use the frameworks to design two new sorting-based permutation generation algorithms, one of which is optimal.
