Expt. 2: Can nice strategies beat out nasty strategies?
Your ObjectiveConduct simulations of a population initially composed of an equal mix of cheats (ALLD), tit for tat (TFT), grudgers (GRU) and random (RND) to determine which strategies tend to be more successful in the long-term.
QuestionsBased on your results, answer the following questions:
In a mixed population where initialy TFT, Grudger, ALLD and Random are at equal frequency, which strategies are the most successful long-term?
In a population composed of TFT, Grudger, ALLD and Random, which strategies are nice and which are nasty?
What are the characteristics of a very successful strategy in in the Prisoner's Dilemma Game?
|" A nice strategy like Tit for Tat does well in a mixed population, but is it tough enough to invade and persist in a population initially dominated by nasties? Let's find out... "|
