The Prisoner's Software Dilemma

The Prisoner's Dilemma is a famous model in game theory. I am far from an expert in game theory - although I did have the pleasure of meeting Prof. Israel Aumann, nobel laureate in economics and world game theory expert - but I can grasp, and sometimes explain, some of the basics. The Prisoner's Dilemma describes a situation wherein if everyone cooperated, they would have the best outcome. However, because they are prisoners and cannot coordinate with others, they make independently rational decisions.
