WebMay 12, 2024 · 1. Fisher–Yates shuffle（Fisher and Yates' original method）. 由 Ronald Fisher 和 Frank Yates 提出的 Fisher–Yates shuffle 算法思想，通俗来说是这样的：. 假设有一个长度为 N 的数组. 从第 1 个到剩余的未删除项（包含）之间选择一个随机数 k。. 从剩余的元素中将第 k 个元素删除并 ... 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. Their description of the algorithm used … See more The "inside-out" algorithm The Fisher–Yates shuffle, as implemented by Durstenfeld, is an in-place shuffle. That is, given a … See more Care must be taken when implementing the Fisher–Yates shuffle, both in the implementation of the algorithm itself and in the generation of the random numbers it is built on, otherwise the results may show detectable bias.
