WebApr 30, 2024 · The Fisher-Yates algorithm is named after Ronald Fisher and Frank Yates. It’s an algorithm used to shuffle a sequence of finite items, like an array for instance. The algorithm works by swapping a random element from your array with the last element in that array repeatedly. Here are the steps taken by the algorithm to shuffle an array: WebNov 17, 2024 · The Fisher-Yates shuffle algorithm, implemented in 1964 by Durstenfeld and described by Donald Knuth, is an efficient and correct way to sort arrays. It provides a useful, versatile shuffling routine. The implementation here has been tested and analyzed to ensure it is relatively free of problems. Dot Net Perls is a collection of tested code ...
