On a grid, a group of agents each carry an action (strategy) and move randomly; at each step, they pair up with a neighbour, play a round of a game, receive a payoff, then update their action. The update rule is straightforward — look at the neighbours' scores, and in the next step switch to the strategy with the higher score.&lt;/p&gt;
&lt;p&gt;There is only one key variable: &lt;strong&gt;which score do you compare?&lt;/strong&gt;&lt;/p&gt;</description></item></channel></rss>
