Fundamentals of Game Theory

Semester 2 · 71083 · Doktoratsstudium in Informatik · 1KP · EN

Game theory is the study of strategic interaction, that is, how individuals or institutions make decisions when outcomes depend not only on their own actions but also on the actions of others. From analyzing competitive markets and political negotiations to modeling evolutionary behavior and powering modern AI systems, game theory has become a cornerstone of understanding rational decision-making in complex environments.

This course offers an introduction to the foundational principles of non-cooperative game theory, focusing on how rational agents make strategic decisions. Students will explore key concepts such as players, strategies, payoffs and equilibria, delving into classic models like the Prisoner’s Dilemma, Coordination Game, Cournot competition, and others. The course also covers advanced topics including evolutionary game theory and applications of GT to machine learning, discussing also implementative details.
