Does anyone know the algorithm behind how the cards are dealt? My main question is whether the program must deal every card in a deck, (presumably at random) and then can proceed with the next deck. Or if it does the above with, say, two (or more) decks at once. Or if it simply deals completely random cards.

For example, if the algorithm must deal from one deck at a time, then the card you've just seen is unlikely to show up again for a while. But if every card is random, then you're as likely to see that card show up as any other card.

Thanks!

i think you'll have to wait for batankyu to answer you.

It appears that its a shuffled deck or that a no real card situation applies and that its as if you log on for every hand. However u do get a sequential run of luck on a certain avatar, before switching that luck to others and vice verse. But who knows what happens in real terms, I am guessing.

For the Poker table, a single deck is shuffled at each hand
prolly using an implementation of the Fisher-Yates method
http://en.wikipedia.org/wiki/Fisher%E2%80%93Yates_shuffle

It prolly starts from an sorted fresh new deck at each hand too
instead of getting back the cards of the previous hand in some defined way.

i have no idea if the soft feels the need or not
to burn 3 virtual cards before flop, turn and river...

The soft has known bugs regarding shuffling and/or dealing:
there was a time the Omaha tourney was dealing two deuces to every player
and flopped two deuces for every first hand of a tourney.

As far as sorted fresh decks are concerned,
we can fairly assume that the decks are sorted according to
the encoding of the cards, each card being encoded by an integer in the range 0..51.

The encoding of a deck at poker tables differs from the encoding of a deck at blackjack tables:

-- Poker tables use the following encoding:
2c=00, 3c=01, 4c=02, ..., Qc=10, Kc=11, Ac=12 (clubs)
2d=13, 3d=14, 4d=15, ..., Qd=23, Kd=24, Ad=25 (diams)
2h=26, 3h=27, 4h=28, ..., Qh=36, Kh=37, Ah=38 (hearts)
2s=39, 3s=40, 4s=41, ..., Qs=49, Ks=50, As=51 (spades)
... that is, clubs first, then diams, then hearts, and finally spades, from deuce to ace.

-- Blackjack tables use the following (orthogonal) encoding:
2c=00, 3c=04, 4c=08, ..., Qc=40, Kc=44, Ac=48 (clubs)
2d=01, 3d=05, 4d=09, ..., Qd=41, Kd=45, Ad=49 (diams)
2h=02, 3h=06, 4h=10, ..., Qh=42, Kh=46, Ah=50 (hearts)
2s=03, 3s=07, 4s=11, ..., Qs=43, Ks=47, As=51 (spades)
... that is, deuces first, then treys, ..., then Kings, and finally Aces, from clubs to spades.

A fresh sorted deck is just the sequence of codes:
00, 01, 02, 03, ..., 48 , 49, 50, 51.

Therefore, a fresh poker deck is sorted by suits first: 2c..Ac,2d..Ad,2h..Ah,2s..As.
while a fresh blackjack deck is sorted by ranks first: 2c,2d,2h,2s,....,Ac,Ad,Ah,As.
Then, Fisher-Yates is applied to shuffle them.

Thanks batankyu!

Bat you know that I now complete understand........:-))))

Thanks Bat thats a lot clearer now. Its just like looking into my fish pond,Lol.

Way above me, but thanks for your interlectual approach your very clever.

Probe it, you might find Ron at the bottom...

Confession?
