FedEx versus Djoker: Through the Lens of game Theory

Executive Summary:
Being inspired by the recent clash between Federer and Djokovic in Wimbledon 2012, we as a group decided to explore the game theory dynamics of this celebrated matchup. Both these players have faced each other quite often at crucial junctures resulting in exciting matches. There are two aspects of this game that we wish to analyze. At first, how the relative strengths of these players determine the outcome of the game. While …show more content…

For this we used primary data collected by observing matches between the two players and secondary data available in the form of serve statistics.
In total we collected data for 300 points played over 8 matches. The rationale behind these pay-offs is the success rate associated with each player’s strategy as shown below.

We begin looking for a mixed strategy by verifying that there is no pure strategy equilibrium. When we examine the above payoff table, we find that strategy M for Federer is a dominated strategy. So the payoff table is modified as below. This is an extension of the point stated above that for a mixed strategy equilibrium a player uses only two of his pure strategies. Clay Court
