Simulations of <b> time steps, with group size </b><b> and </b> agents per group.

<p>From <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0111022#pone.0111022.e136" target="_blank">equation 7</a>, we set , and . The noise component, has mean 0 and . Shown are proportions of the 10,000 total agents who have made one of the two possible two choices, one shown as red and one shown as blue, through time. The different plots show simulations with varying starting points for each proportion. The payoffs and are chosen from from time-varying normal distributions , and and are both chosen from time-varying normal distributions . Gray bounds show 95% quantiles for sample paths over group and red/blue curves show the mean paths for proportion over groups.
