Comparison of update mechanisms in social dilemmas for structured populations.

<p>Parameter regions for cooperation in social dilemmas: predictions for well-mixed versus structured populations. The solid blue lines indicate predictions for under different updates: (a) DB, (b) mixed BD-DB for , and (c) BD in structured populations. In well-mixed populations the condition is the same as (c). Population structure can extend the parameter region where cooperation is favored. The shaded area marks the extended parameter region, which has no biological interpretation in this framework.
