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 … Web3. Using Fisher-Yates Shuffle Algorithm. Another good alternative is to use Fisher–Yates shuffle to generate random permutations. The algorithm does a linear scan of the vector and swaps each element with a random element among all remaining elements, including the element itself.
