A simple clojure module that is meant to simulate the action of shuffling a collection as if it were a deck of cards.
All shuffle types support an optional second parameter to perform the shuffle multiple times.
Predictable behaviours that make a human riffle shuffle imperfect
- Once a deck of cards is divided to each hand, the amount of cards in each hand is not (likely) equal.
- As each thumb releases from it's half of the deck, sometimes more than one card drops from a single hand at a time.
(riffle coll times)Predictable behaviours that make a human overhand shuffle imperfect
- Random amounts of cards (chunks) are taken from the top and placed placed in the opposite hand in reverse order (retaining the order within each chunk)
(overhand coll times)A very predictable shuffle, alternating placing the top card on the bottom/top of the new deck
unit tests included
(mongean coll times)Predictable shuffle, dealing items into N piles and then rejoining the piles
unit tests included
; `piles` is how many piles to use
