WebAug 2, 2024 · 11. I'm using the standard Fisher-Yates algorithm to randomly shuffle a deck of cards in an array. However, I'm unsure if this will actually produce a true distribution of all possible permutations of a real-world shuffled deck of cards. V8's Math.random only has 128-bits of internal state. Since there are 52 cards in a deck, 52 factorial would ... WebThat’s a Fisher-Yates shuffle. It was invented by Ronald Fisher and Frank Yates in 1938, originally as a method for researchers to mix stuff up with pencil and paper. In 1964, Richard Durstenfeld came up with the modern method as a computer algorithm. It has a run time complexity of O(n).
