Generous Tit for Tat is the biologically most successful strategy for playing the prisoner’s dilemma. If they both defect, each gets 1. This is a recreation of Robert Axelrod's tournament which pit many strategies against each other to find out which performed the best in a repeated Prisoner's Dilemma game. He invited a number of well-known game theorists to submit strategies to be run by computers. This is a paper to reproduce and explore Axelrod's second tournament. The inputs for it are much more complex, but it can be started, stopped, and predicted using it’s input, so it’s an algorithm. Replicating the Axelrod Tournaments. The ultimate goal of Rvision is to provide R users with all the necessary functions to read and manipulate images, videos and camera streams, with an emphasis on speed (thanks to OpenCV).
