The evolution of cooperation through imitation
Kandori, Mailath and Rob [1993] and Young [1993] showed how introducing random innovations into a model of evolutionary adjustment enables selection among Nash equilibria. Key to this result is that poorly performing strategies may be introduced in sufficient numbers that they begin to perform well. We examine imitation as an alternative propagation mechanism. If imitation is much more likely t...

15 صفحه اولCooperation through imitation
This paper characterizes long-run outcomes for broad classes of symmetric games played over time, when players select actions on the basis of average historical performance. Received wisdom is that, in those environments where agent’s interests are partially opposed, behavior is excessively competitive: “keeping up with the Jones’ ” lowers everyones’ welfare. Here, we study the long-run consequ...
متن کاملEvolution Through Imitation in a Single Population
Kandori, Mailath and Rob [1993] and Young [1993] showed how introducing random innovations into a model of evolutionary adjustment enables selection among Nash equilibria. Key to this result is that poorly performing strategies may be introduced in sufficient numbers that they begin to perform well. We examine imitation as an alternative and more plausible propagation mechanism. If imitation is...
متن کاملOn the Evolution of Behaviours Through Embodied Imitation
This paper describes research in which embodied imitation and behavioural adaptation are investigated in collective robotics. We model social learning in artificial agents with real robots. The robots are able to observe and learn each others’ movement patterns using their on-board sensors only; so that imitation is embodied. We show that the variations that arise from embodiment allow certain ...
