Computers: New Idea for Prisoner's Dilemma

Wired has a story on a new strategy for the classic game "Prisoner's Dilemma." For those of you not familiar with the game, a good summary is provided in the article. The previous winner, known as "Tit for Tat," has been described as the model for mutually assured destruction during the Cold War. However, this strategy was defeated by University of Southampton's recognition of similar programs followed by a "master/slave" relationship strategy. Programs that were not considered exactly the same automatically received hostile treatment.

I, for one, can't say I'm surprised that this new strategy is considered more effective. What is Bush's foreign policy if not "Let us take advantage of you or we'll do everything in our power to make your life miserable?"
