Abstract

Parrondo's paradox, due to Spanish physicist Juan Parrondo (1996), states that a player may alternate regularly or randomly between two negative-expectation games to achieve a positive- expectation game. There are a variety of games that exhibit the Parrondo paradox, including capital-dependent games, history- dependent games, multi-player games, and cooperative games. This talk will survey the subject and also discuss some work in progress concerning the asymptotic behavior of the Parrondo player's profit.
