WebFeb 21, 2024 · 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 个元素删除并取出,放到新数组中。. 重复第 1、2 … Web而且Fisher-Yates洗牌算法的思路极为简单巧妙,直接对数组元素进行操作(随机调换),也不需用到多重循环和排序算法等高复杂度的设计,堪称洗牌算法中的经典。 虽说应该都是无偏的随机打乱的洗牌算法,但思路不一样,且效率差距惊人。
Randomness is hard: learning about the Fisher-Yates …
WebThe 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 remain. WebTime complexity is O(N log N), same as quick sort. Space complexity is O(N). This is not as efficient as a Fischer Yates shuffle but, in my opinion, the code is significantly shorter and more functional. If you have a large array you should certainly use Fischer Yates. If you have a small array with a few hundred items, you might do this. bin valley angle
