Simulation for reactive strategies in the Iterated Prisoner's Dilemma

This is a MATLAB implementation of the simulation presented in the 1992 paper "Tit for tat in heterogeneous populations" by Nowak and Sigmund. It allows reproducing the results presented in the paper or running the same experiment with different parameter values (payoff values, population size).

Start with the script "TFT_in_a_heterogeneous_population.m" which runs the simulation exactly as presented in the article and produces the same figures.
