Fisher 和 Frank Yates,即 Fisher–Yates Shuffle,其基本思想就是从原始数组中随机取一个之前没取过的数字到新的数组中,具体如下: 1. 初始化原始数组和新数组,原始数组长度为n(已 … The Fisher–Yates shuffle is an algorithm for generating a random permutation of a finite sequence—in plain terms, the algorithm shuffles the sequence. The algorithm effectively puts all the elements into a hat; it continually determines the next element by randomly drawing an element from the hat until no elements … See more The Fisher–Yates shuffle, in its original form, was described in 1938 by Ronald Fisher and Frank Yates in their book Statistical tables for biological, agricultural and medical research.
