Lunch isn't free --- but cells are: evolving FreeCell players

The application of computational intelligence techniques within the vast domain of games has been increasing at a breath-taking speed. Over the past several years our research group has produced a plethora of results in numerous games of different natures, evidencing the success and efficiency of evolutionary algorithms in general --- and genetic programming in particular --- at producing top-notch, human-competitive game strategies. Herein, we describe our study of the game of FreeCell, which produced two Gold Humie Awards. Our top evolved FreeCell player is the best published player to date, able to convincingly beat high-ranking human players.
