ch (brute-force is actually my favorite first approach), generating all possible deals and then filtering duplicates using a set of "already been seen" deals. A smarter algorithm would generate only the unique deals. If someone were paying me to be that smart, maybe I'd work on it. I'm guessing this is an attempt to optimize a deck for playing a card game like Magic or Pokemon, etc. Your plan is, given a set of 'n' cards in your collection (presumbaly n>60, or there would be no problem to solve), to compute all possible decks of 60 cards. Then you have some function to evaluate this deck, or perhaps simulate playing it against another deck. You will then exhaustively run this simulation function against each deck to find which deck from your collection of 100's of cards is the "best".
