Random Shuffle & Fisher-Yates Algorithm
3 years ago
72
This lecture introduces the random permutation (aka random shuffling) problem. We can use Fisher-Yates algorithm for randomly shuffling a sequence. This lecture introduces the two versions of the Fisher-Yates shuffle. The original version [Fisher-Yates 1938] has quadratic time complexity. The modern version [Durstenfeld 1964] has linear time complexity.
