Introducing John Nash, who invented "The Prisoner's Dilemma",
John Nash was educated at both Bachelor and Masters level in mathematics at Carnegie Institute of Technology. He went on to Princeton University to work towards his doctorate, which he completed in 1950 with the publication of his ‘Non-cooperative Games’ thesis in which he laid down the mathematical foundations of games theory (brought to popular culture in the film ‘A Beautiful Mind’).
In mathematics, games theory looks at situations where two (or more) participants have a range of possible choices that they can take. Each decides which choice to make in the light of others' choices, since the outcome is produced by the particular combination of their choices. The 'Nash Equilibrium' is the outcome which would be produced by each making the best choice, given their knowledge of others' choices.
One of the classic examples of games theory is the ‘Prisoner’s Dilemma’. Discover this for yourself with the Open University's interactive version of the Prisoner's Dilemma.
