Game Theory

In this elective you will be introduced to Game Theory, a branch of Mathematics concerned with strategy. There are players who can choose between certain actions, and their strategies depend on the payoffs of these actions. We’ll consider the classic example: the prisoner’s dilemma, and see how the ideas can be developed further by consideration of iterated elimination of strictly dominated strategies. We’ll then consider the mathematical analysis of zero-sum games. We will consider payoff matrices, play-safe strategies, saddle points, dominance and mixed strategy games. To illustrate the mathematical analysis, we will also play some games and discuss their strategy. To round up the course you will select from a series of topics relevant to game theory and present your findings to the class.

Teacher Profile

Mr Williams has taught Maths and Further Maths for over ten years prior to joining Highgrove Education, most recently at Harrow School Online, where in 2023 his pupils achieved 90% A*-A in Maths and 100% A*-A in Further Maths. Before this he taught at Abingdon School where he was responsible for their UKMT challenges and Sixth Form Maths Enrichment. Mr Williams graduated with a First class Masters degree in Mathematics from the University of Sussex in 2013, then went on to complete his PGCE with the University of Reading. He is a keen advocate for the power of technology to enhance and indeed transform pupils’ enjoyment and understanding of Mathematics.
