The algorithm generates a random permutations uniformly so long as the hardware operates in a fair manner. In 2015, Bacher et al. produced MERGESHUFFLE, an algorithm that divides the array into blocks of roughly equal size, uses Fisher—Yates to shuffle each block, and then uses a random merge recursively to give the shuffled array.

The Fisher-Yates shuffle (or Knuth shuffle) is an algorithm developed in 1938 and popularized in 1964 for shuffling lists using random numbers. In 1999, Intel added a hardware-based random number generator to the Pentium III, which combined oscillator outputs to generate random numbers.
A simple algorithm to generate a permutation of n items uniformly at random without retries, known as the Fisher–Yates shuffle, is to start with any permutation (for example, the identity permutation), and then go through the positions 0 through n − 2 (we use a convention where the first element has index 0, and the last element has index n − 1), and for each position i swap the element ...

Perfect shuffle may refer to: Faro shuffle , in particular the interpretation whereby cards (or more generally, entities in sequence) are divided into two equal piles and interleaved. Any shuffling algorithm that guarantees perfect randomness (all possible orders with equal probability), such as the Fisher–Yates shuffle .
Tommy Vietor, a former Barack Obama aide and “Pod Save Save America” co-host, summarized Patel’s “random enemies list” as “basically just Obama staff and Republicans who were mean to ...
Random number generators are important in many kinds of technical applications, including physics, engineering or mathematical computer studies (e.g., Monte Carlo simulations), cryptography and gambling (on game servers). This list includes many common types, regardless of quality or applicability to a given use case.
