Impact of a Spatial Component on Group Selection

A set of group selection models implemented by Akendiz and Van Veelen showed that the
evolution of cooperation (altruism) is hindered when groups interact predominantly with
neighboring groups as opposed to the global population. This diverges from studies of
cooperation among populations of individuals, (Taylor, and Wilson, et al) which observes an
effect called the cancellation effect among the cooperative individuals. This paper analyzes a
more complex model of a group-structured population in which the groupsí locations change
stochastically, and aims to identify the impact on the evolution of cooperation. Overall, this paper
finds that the cancellation effect observed holds for group-structured populations.
