Title:A Model of Evolution of Cooperation in Iterated Prosoner'S Dilema
Date: 1992
Abstract:Genetic Algorithms are used to develop a system to simulate the Iterated Prosoner's Dilema Game (IPD). The strategies of the players are represented as random arithmetic expressions evaluating to minus (defect) or zero or positive (cooperate). The game is played in a round robin tournament with a fixed size of population. After each tournament strategies (expressions) are evaluated based on their score. Genetic operators: Crossover and Mutation are used to give right to produce more to the better performing expressions. The study aims to create an environment to observe evolution of cooperation in IPD through learning among strategies. Keywords: Prosoner's Dilemma, Adaptive Systems, Machine Learning, Genetic Algorithms and Evolution.
