关于[Permutations: Fast implementations and a new indexing algorithm allowing multithreading]的摘要:
This article is the continuation of a StackOverflow question asked by SimpleVar: “Generating permutations of a set (most efficiently)”. It shows many fast implementation of permutation algorithm. There is also a contribution by providing a unique way to index permutation allowing to get a specific permutation based on lexicographical order.
