Web9 mei 2014 · As Fnord points out below, a deck of 60 cards that has been pile-shuffled three times and then riffled once might look, to the naked eye, similar to decks of 60 that had been riffled a full 8 times. More generally, people tend to make the assumption that pile shuffling is random simply because it looks random. WebEach time the product is run, you get a different set of cards in the output. You can also change the number of cards that are shuffled and provided in the output. The product function is used in a program that is available in the itertools module. The function creates a deck of cards by conducting the Cartesian product of two sequences.

WebIn this paper a mathematical model of card shu†ing is constructed, and used to determine how much shu†ing is necessary to randomize a deck of cards. The crucial aspect of this model is rising sequences of permutations, or equivalently descents in their inverses. The probability of an arrangement of cards occuring under shu†ing is a ...
