Abstract :
The iterated prisoner´s dilemma (IPD) game has been extensively investigated to help researchers gain a better understanding of how cooperation develops in populations. One criticism of IPD is it underestimates the level of cooperation particularly in human populations. The iterated snowdrift (ISD) game has emerged as a viable alternative model, in part because it predicts higher cooperation levels. To date no numerical analysis of ISD has been done. In this paper we report the results from a numerical analysis conducted on an ISD with an N-player, well-mixed population. Our results show, with certain cost-to benefit ratios, evolved ISD strategies can maintain surprisingly high quasi-stable levels of cooperation in the population.
