課程概述

Evolution is a central theme in biology. Understanding evolution is also very important in the study of agricultural, medical, computer and social sciences. This course introduces the basic mathematical principles of evolutionary game theory and how cooperation emerges among selfish individuals. The contents cover the Nash equilibrium, evolutionarily stable strategy, social dilemmas of cooperation, effects of direct and indirect reciprocity, and models involving reputation.
