difference between prisoner's dilemma and tragedy of the commons
Prisoner's dilemma Many real-life dilemmas involve multiple players.[29] Although metaphorical, Hardin's tragedy of the commons may be viewed as an example of a multi-player generalization of the PD: Each villager makes a choice for personal gain or restraint. The collective reward for unanimous (or even frequent) defection is very low payoffs (representing the destruction of the "commons"). A commons dilemma most people can relate to is washing the dishes in a shared house. By not washing dishes an individual can gain by saving his time, but if that behavior is adopted by every resident the collective cost is no clean plates for anyone.
The Prisoner of Zenda The name of the villain in The Prisoner of Zenda, Rupert of Hentzau, is the title of the sequel novel, Rupert of Hentzau (1898), published four years later, and is included in some editions of The Prisoner of Zenda. The popularity of the novels inspired the Ruritanian romance genre of literature, film, and theatre that features stories set in a fictional country, usually in Central Europe and Eastern Europe, such as Ruritania, the Central European realm that named the genre,[1] which includes the Graustark novels by George Barr McCutcheon.
