Consider a population of farmers who live around a lake. Each farmer engages in trade with his m adjacent neighbors, where m is termed the span of interaction. Trade is governed by a prisoner's dilemma rule of engagement. A farmer's payoff is the sum of the payoffs from the m prisoner's dilemma...

Consider a population of farmers who live around a lake. Each farmer engages in trade with his two adjacent neighbors. The trade is governed by a prisoner's dilemma 'rule of engagement'. A farmer's payoff is the sum of the payoffs from the two prisoner's dilemma games played with his two...

In a haystack-type representation of a heterogeneous population that is evolving according to a payoff structure of a prisoner's dilemma game, migration is modeled as a process of swapping" individuals between heterogeneous groups of constant size after a random allocation fills the haystacks,...
