WebSep 13, 2024 · The Fisher-Yates shuffle is an algorithm for generating random arrangements of finite linear arrays. It is unbiased, so the probability of each point being randomly selected is the same. The modern version is more computationally efficient and does not require additional storage space. 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:
