However, the focus on evolution of the entire population where each and every individual s contribution is critical is new to the best of our knowledge. We define an abstract version of the Tragedy of the Commons problem as follows: a shared resource can effectively support N units of load, but ....

....thn four) rounds per gme This pper focuses on the bsic effects of using tgs under wriety of model prmeter settings, including wrying mutation pressure, the extent nd cost of tg searching, the number of other gents played per generation nd the number of rounds played per gme. A subsequent pper [Riolo, 1997] explores tg dynamics in detail, in order to better understand how they ffect population performance dynamics. The next section describes the model in detail. Section 3 compares the hvior of the model when individuals do nd dont use tgs to select prtners. Section 4 explores the effects of wrying ....
....mutual defection to reciprocity, and (2) enables more stability of reciprocity, in that (given any of a fairly broad range of parameter settings) populations that use tags have far fewer and less severe crashes into mutual defection than do populations that do not use tags. A subsequent paper [Riolo, 1997] explores in more detail exactly how tags change the dynamics of populations of IPD players. That paper also examines the dynamics of the tags themselves, showing how tags that are originally arbitrary labels come to take on meaning, and demonstrating that a kind of mimicry plays an important role ....
