In this talk we re-examine the utility foundations of game theory. We present a simple and intuitive model of a game defined precisely by each player’s preference orders of their strategies, given the strategies of the other players. These orders define a graph called the ‘response graph’ of the game. We discuss why the response graph is a natural model. Most importantly, we find that the graph-based approach leads to new insights and predictions that improve upon our understanding of game theory, particularly evolution in game.

Previously, he had been an Associate Professor at the Department of Electrical and Electronic Engineering, the University of Melbourne from 2014 to 2020 and a Senior Lecturer and a McKenzie fellow at the same department from 2012 to 2014, and before that he was an ACCESS Postdoctoral Researcher at the ACCESS Linnaeus Centre, the KTH Royal Institute of Technology, Stockholm, Sweden. He received his B.Sc. degree in Electrical Engineering from Shiraz University in 2006, and the Ph.D. degree in engineering from the Australian National University, Canberra, Australia in 2011. His current research interests include, but are not limited to, decision making for dynamical systems under uncertainty, optimisation theory and its application in control and estimation, and mathematical systems theory of cyber–physical systems.
